Why are dark matter and dark energy described as "dark"? A. Because they emit blackbody radiation. B. Because they absorb light. C. Because they are only found in shadows. D. Because we cannot easily detect them.

HELP ME PLZ!!

Answers

Final answer:

Dark matter and dark energy are termed 'dark' because they do not emit, absorb, or reflect light, which makes them invisible to traditional detection methods such as telescopes; they are detectable only through their gravitational effects.

Explanation:

Dark matter and dark energy are described as "dark" not because they emit blackbody radiation, absorb light, or are merely found in shadows, but because they are difficult to detect by conventional means. The correct answer is D. Because we cannot easily detect them. Dark matter does not emit, absorb, or reflect any light, making it invisible to traditional telescopes that detect electromagnetic radiation. Astronomers infer its existence through the gravitational effects it has on visible objects, such as the rotation curves of galaxies and the gravitational lensing of light from distant objects.

The term "dark" in dark matter and dark energy refers to the fact that these components do not interact with electromagnetic radiation in a way that allows us to detect them directly. Dark matter makes up approximately 80% of the matter in the Universe, and its presence is known primarily through its gravitational influence. Similarly, dark energy is hypothesized to be responsible for the observed acceleration of the expansion of the Universe. However, its nature remains a profound mystery in physics.

correctly.
C + O2 →?

Answers

Answer:

CO₂

Explanation:

The equation that you have to complete is:

C + O₂ → ?

This is, you have to find the products formed and the coefficients in front of each substance to balance the chemical equation.

Carbon may react with oxygen using oxidation number 2 or 4.

If carbon uses oxidation number 2, the chemical equation is:

2C + O₂ → 2CO

If carbon uses oxidation number 4, the chemical equation is:

C + O₂ → CO₂

Normally, an incomplete combustion yields to a mixture of products: both CO and CO₂, and it only happens when the amount of oxygen is limitied.

When there is plenty of oxygen available, the combustion is complete and the only product of the reaction is CO₂.

With that information, and the fact that the list of choices do not include CO as product, you conclude that this is a complete combustion, and the chemical equation is:

C + O₂ → CO₂

So, the choice that completes the chemical equation is CO₂.

Answers

Answer:

evaporation

faster

weeker

Final answer:

Liquid water changes to a gas through boiling; gas particles move faster and have weaker attractions than in the liquid state. This is due to higher kinetic energy overcoming hydrogen bond attractions. Water's unique properties, including ice being less dense than liquid water, are a result of hydrogen bonding.

Explanation:

When liquid water is heated, it will eventually change to a gas through boiling. Gas particles move faster and have weaker attractions between particles than liquid particles. The transition from the liquid phase to the gas phase happens at a substance's boiling point, which is a physical property of the liquid. The process whereby water transforms into gas is closely linked to the kinetic energy of its molecules and the breaking of hydrogen bonds. As water reaches its boiling point and is further heated, the water molecules gain enough energy to break free from the attraction that holds them together in the liquid state, allowing them to escape and spread out as a gas.

The unique properties of water, including its ability to exist as a gas, liquid, and solid, stem from its capacity to form hydrogen bonds. These bonds cause water to behave differently than other substances. For example, unlike most substances, ice (solid water) is less dense than liquid water because the hydrogen bonds cause the molecules to be structured in a way that takes up more space.

Why can people on one side of a room smell the scent of an air freshener sprayed on the opposite side?

Answers

People on one side of a room can smell air freshener sprayed on the opposite side due to the diffusion of molecules and the increase in entropy. Olfactory receptors in our noses detect these molecules, which allows us to perceive the scent as it spreads throughout the room.

The reason people on one side of a room can smell an air freshener sprayed on the opposite side is due to the diffusion of air freshener molecules from an area of higher concentration to an area of lower concentration. This happens because the entropy of the molecules increases, meaning they spread out to evenly fill the available space, which is why the scent diffuses throughout the room. Since molecules are always in motion, the ones released from the air freshener bottle will move around and mix with air molecules until they are distributed throughout the entire room.

Olfaction, or the sense of smell, allows us to detect these molecules. Humans have many olfactory receptors that can sense a wide range of odors. When molecules from the air freshener reach the receptors in our noses, they bind to them and trigger a signal to the brain, allowing us to perceive the scent. Therefore, although the air freshener is sprayed on one side of the room, the molecules eventually reach and are detected by people on the other side as well.

Given SiO2 + 4HF --> SiF4 +2H2O
in this chemical equation how many grams of HF are needed for 182 grams of SiO2 to react completely?

Answers

Answer:

=242.47 g of HF

Explanation:

From the equation One mole of SiO₂ (Silicon (IV) Oxide) react with 4 moles of HF (Hydrogen fluoride).

This is because the reaction ratio is 1:4

The number of moles in182 grams of SiO₂ is:

Number of moles= Mass/RMM

RMM of SiO₂ is 60.08 g/mol

No. of moles=182g/60.08g/mol

=3.0293 moles.

The reaction ratio of SiO₂ to HF is 1:4

Thus the number of moles of HF required to react with  3.0293 moles of SiO₂ is:

(4×3.0293)/1= 12.1172 moles

The mass of 12.1172 moles of HF is.

12.1172 moles× RMM of HF

=12.1172 moles×20.01 g/mol

=242.47 g of HF

how many grams of sodium chloride can be produced from 46.3 g of sodium hydroxide?

Answers

Answer:

=67.65 grams of sodium chloride.

Explanation:

In this explanation, we shall assume that the limiting reagent was NaOH only and the amount of HCl used was sufficient.

NaOH + HCl → NaCl + H₂O

In the equation, the ratio of NaOH used to the NaCl produced will be 1:1

The number of moles of NaOH in 46.3 g.

Number of moles = mass/RMM

=46.3g/40g/mol

=1.1575 moles.

Since the reaction ratio is 1:1, the Number of moles of NaCl produced is also 1.1575 moles.

The mass of 1.1575 moles of NaCl is: 1.1575 moles ×  58.443g/mol

=67.65 grams of sodium chloride.

46.3 grams of sodium hydroxide can theoretically produce 67.64 grams of sodium chloride, based on a 1:1 mole ratio and molar masses from the balanced chemical reaction NaOH + HCl → NaCl + H₂O.

To determine how many grams of sodium chloride can be produced from 46.3 grams of sodium hydroxide, we must first write a balanced chemical equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl), which typically produces sodium chloride (NaCl) and water (H₂O):

NaOH + HCl → NaCl + H₂O

This equation shows that one mole of sodium hydroxide reacts with one mole of hydrochloric acid to produce one mole of sodium chloride and one mole of water. The molar masses of these compounds are approximately:

Sodium hydroxide (NaOH): 40.00 g/mol

Sodium chloride (NaCl): 58.44 g/mol

To find the amount of sodium chloride produced from 46.3 g of sodium hydroxide, use the mole ratio from the balanced equation and the molar masses:

Calculate the moles of NaOH: (46.3 g NaOH) / (40.00 g/mol) = 1.1575 mol NaOH

Use the 1:1 mole ratio between NaOH and NaCl to find moles of NaCl: 1.1575 mol NaOH ⇒ 1.1575 mol NaCl

Convert moles of NaCl to grams: (1.1575 mol NaCl) ⇒ (1.1575 mol) ⇒ (58.44 g/mol) = 67.64 g NaCl

Therefore, 46.3 grams of sodium hydroxide can theoretically produce 67.64 grams of sodium chloride.

4. You have a very concentrated solution (12 M) of potassium chloride (KCI). You need it to be at the least concentration possible for the experiment you are
about to conduct. The problem is you forgot to order lab supplies, so you only have 2 L of distilled water left. What would be the final concentration if you
added the two 2 L of distilled water to the 0.5 L of 12 M KCI?
a 3.0 M
b 24 M
C 2.4M
d 48 M

Answers

Answer:

C. 2.4 M

Explanation:

Because you started with 12M solution of KCl, that means that there was a concentration of 12 mols of KCl per Liter of solution. (12mol/1L =12 M). Since there was only 0.5L of solution, there was only 6 mols of KCl because there is only 12 mols per 1 Liter, so half of that volume would have half the amount of solute to keep that true. (6mol/.5L = 12 M). With the new water added, the formula becomes (6mols KCl/ 2.5L of water =2.4 M)

After diluting 0.5 L of a 12 M potassium chloride (KCl) solution with 2 L of distilled water, the final concentration will be 2.4 M.So,option C is correct.

The final concentration of potassium chloride (KCl) after dilution, we can use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.

Starting with 0.5 L of a 12 M KCl solution and adding 2 L of distilled water, the final volume (V2) is 0.5 L + 2 L = 2.5 L.

Using the formula, we get:

12 M times 0.5 L = M2 times 2.5 L

So, the final concentration (M2) is:

M2 = (12 M times 0.5 L) / 2.5 L = 2.4 M

Therefore, the final concentration of the KCl solution would be 2.4 M.

Answers

F2 because it’s the strongest

From the provided options, Na (sodium) is the strong reducing agent because it more readily donates its valence electron to reduce other substances.

The element that would be a strong reducing agent from the list provided is Na (sodium). A reducing agent is a substance that donates electrons to another substance in a chemical reaction, thereby reducing the oxidation state of that substance.

The four options given are two halogens, F2 and Cl2, which are strong oxidizing agents rather than reducing agents, and two metals, Ba (barium) and Na.

Between the metals, sodium is more active and thus a stronger reducing agent. This is because sodium is more willing to lose its single valence electron to form the Na+ ion, facilitating the reduction of other substances.

how is mass conserved when cooking an egg?


Guys I need help urgent​

Answers

Answer:

The egg is changed from liquid to solid

Explanation:

The law of conservation of mass states that "Matter/mass can neither be created nor destroyed but can be converted from one form to another".

Inside of the Egg is liquid in nature and during the process of cooking the egg the liquid changes to solid.

THAT IS HOW MATTER IS CONSERVED WHILE COOKING AN EGG

Final answer:

The mass is conserved when cooking an egg because no mass is lost or gained during the process.

Explanation:

When cooking an egg, the mass is conserved because no mass is lost or gained during the process. The egg goes through a physical and chemical change, but the total mass remains the same. For example, when boiling an egg, the water in the pot evaporates but becomes part of the surrounding gas in the air, so no mass is lost. Additionally, the proteins in the egg denature and solidify, but their mass remains the same.

The conservation of mass principle, also known as the law of conservation of mass, is a cornerstone of chemistry. It is derived from the understanding that atoms are neither created nor destroyed in chemical reactions; they are merely rearranged into different combinations. This means that the total mass of substances involved in a chemical reaction remains constant before and after the reaction.

In the context of cooking an egg, this principle holds true. While physical and chemical changes occur during the cooking process, the total mass of the egg, including its components such as water, proteins, fats, and minerals, remains unchanged. Even though water evaporates from the egg during cooking, the total mass of the system (egg + surroundings) remains constant.

Balance the equation (NH4)3 PO4 +NA0H arrow Na3P04 +3NH3 +3H20.

Answers

Answer:

Explanation:

(NH4)3 PO4 +NaOH arrow Na3PO4 +3NH3 +3H2O

Start by seeing what happens with the Na. You need 3 on the left, so put a 3 in front of NaOH

(NH4)3 PO4 +3NaOH arrow Na3PO4 +3NH3 +3H2O  Next work with the nitrogens. YOu have 3 on the left and 3 on the right, so they are OK. Next Go to the stray oxygens.

You have 3 on left in (NaOH) and three on the right in 3H2O so they are fine as well. The last thing you should look at are hydrogens.

There are 12 + 3 on the left which is 15. There are 9 (in 3NH3) and 6 more in the water. They seem fine.

Why didn't I do something with the PO4^(-3)? The reason is a deliberately stayed away from them and balanced everything else. Since they were untouched with 1 on the left and 1 on the right, they are balanced.

Species      Na        H        O         N       PO4

Left             3          15        3         3          1

Right           3         15         3         3          1

Answer:

(NH₄)₃PO₄ + 3NaOH ⟶ Na₃PO₄ + 3NH₃ + 3H₂O

Explanation:

Your unbalanced equation is

(NH₄)₃PO₄ + NaOH ⟶ Na₃PO₄ + NH₃ + H₂O

A method that usually works for balancing by inspection is

Balance all atoms other than O and H Balance O Balance H

1. Pick the most complicated-looking formula [(NH₄)₃PO₄].

Put a 1 in front of it.

1(NH₄)₃PO₄ + NaOH ⟶ Na₃PO₄ + NH₃ + H₂O

2. Balance N.

We have fixed 3N on the left. We need 3N on the right.

Put a 3 in front of NH₃.

1(NH₄)₃PO₄ + NaOH ⟶ Na₃PO₄ + 3NH₃ + H₂O

3. Balance P.

We have fixed 1P on the left. We need 1P on the right.

Put a 1 in front of Na₃PO₄.

1(NH₄)₃PO₄ + NaOH ⟶ 1Na₃PO₄ + 3NH₃ + H₂O

4. Balance Na

We have fixed 3Na on the right. we need 3Na on the left.

Put a 3 in front of NaOH.

1(NH₄)₃PO₄ + 3NaOH ⟶ 1Na₃PO₄ + 3NH₃ + H₂O

5. Balance O.

We have fixed 7O on the left and 4O on the right. We need three more O atoms on the right.

Put a 3 in front of H₂O.

1(NH₄)₃PO₄ + 3NaOH ⟶ 1Na₃PO₄ + 3NH₃ + 3H₂O

All species have a coefficient. The equation should now be balanced.

6. Check that all atoms are balanced

[tex]\begin{array}{ccc}\textbf{Atom} & \textbf{On the left} & \textbf{On the right}\\\text{N} & 3 & 3\\\text{H} & 15 & 15\\\text{P} & 1 & 1\\\text{O} & 7 & 7\\\text{Na} & 3 & 3\\\end{array}[/tex]

The balanced equation is

(NH₄)₃PO₄ + 3NaOH ⟶ Na₃PO₄ + 3NH₃ + 3H₂O

What is the empirical formula of C6H12O6?

Answers

Answer:

The correct answer would be CH2O,

Explanation:

Empirical Formula of any chemical compound gives us the information about the proportion of the element present in the compound but doesn't tell us about the actual numbers or arrangement of atoms.

C6H12O6 is the formula of Glucose. The empirical formula of Glucose is CH2O. This means that there is one atom of Carbon, 2 atoms of Hydrogen and 1 atom of oxygen is present. It tells us about the ratio of the atoms present in the molecules, like empirical formula of CH2O tells us that the ratio of carbon, hydrogen and oxygen is 1:2:1
