If i'm correct it is carbon dioxide. If i'm not correct sorry!

Explanation:

To solve this we must be knowing each and every concept behind respiration. Therefore, oxygen is the substance which is removed from the air by living things for respiration.

Respiration is a mechanism that happens within cells to produce energy by breaking down glucose molecules. The process may be neatly separated into two groups based on the usage of oxygen: anaerobic and aerobic respiration.

Many people believe that humans as well as other multicellular creatures solely employ aerobic respiration. This is countered by the fact that human muscles perform anaerobic respiration during strenuous activity, creating lactic as a waste byproduct instead of carbon dioxide. Oxygen is the substance which is removed from the air by living things for respiration.

Therefore, oxygen is the substance which is removed from the air by living things for respiration.

The statement for flat iron temperature is "450°F (i.e., 230°C)."

Temperature is the measurement of a body's level of hotness or coolness.

The average kinetic energy of the system is measured by temperature. The kinetic energy of particles in a matter raises as they move faster, which boosts the temperature of the system. When two bodies of differing temperatures come into touch, heat is the energy exchanged between them.

Fine hair strands should be kept at 350–375 degrees Fahrenheit , whereas coarse or thick hair should be at 400–450 degrees Fahrenheit.

Wavy hair can become flat due to heat damage, losing the texture. For some context, 450 degrees Fahrenheit is the temperature at which semi-permanent keratin straightening procedures are performed.

Chelsea should set her flat iron to 450 degrees Fahrenheit, that is 230 degrees Celsius after applying the keratin treatment on Kimi's hair and blow drying it.

Hence, the correct answer is 450°F (i.e., 230°C).

1.00 mole of chlorine gas contains 1.20442815×10²⁴ atoms of chlorine.

The subject of this question is chemistry, specifically moles and atoms. In chemistry, a mole is a unit used to talk about a very large number of things — approximately 6.02214076×10²³, which is known as Avogadro's Number. When you have 1.00 mole of something, you have 6.02214076×10²³ of it. This means that 1.00 mol of chlorine gas (Cl₂) contains 2.00 moles of chlorine atoms. Therefore, 1.00 mol of chlorine gas contains 2.00 x 6.02214076×10²³ = 1.20442815×10²⁴ atoms of chlorine.

Final answer:

In 1.00 mol of chlorine gas, which is diatomic (Cl₂), there are 1.2044 × 10²´ atoms of chlorine, as one mole of Cl₂ contains 6.022 × 10²³ molecules, and each molecule has two chlorine atoms.

Explanation:

To determine how many atoms of chlorine are in 1.00 mol of chlorine gas (Cl₂), we must understand the molecular composition of chlorine gas. Chlorine gas is diatomic, which means each molecule consists of two chlorine atoms. According to Avogadro's number, one mole of any substance contains 6.022 × 10²³ entities (atoms, molecules, etc.). Thus, in 1 mole of Cl₂, there are 6.022 × 10²³ molecules of Cl₂.

Since each Cl₂ molecule contains two chlorine atoms, to find the total number of chlorine atoms in one mole of Cl₂, we simply multiply Avogadro's number by two:

6.022 × 10²³ molecules/mol × 2 atoms/molecule = 1.2044 × 10²´ atoms of chlorine.

Therefore, 1.00 mol of chlorine gas contains 1.2044 × 10²´ atoms of chlorine.

Answer: 0.075

Explanation:

(concentration in molarity)(volume in liter) = answer

0.15 mol/L *0.500L = 0.075 mol

The number of moles of H2SO4 in the given solution is 0.075 moles.

The question is asking how many moles of H2SO4 are present in 0.500 L of a 0.150 M H2SO4 solution.

To answer this question, we can use the equation:

Moles of solute = concentration (M) x volume (L)

In this case, the concentration is 0.150 M and the volume is 0.500 L. Plugging these values into the equation, we get:

Moles of H2SO4 = 0.150 M x 0.500 L = 0.075 mol

Therefore, there are 0.075 moles of H2SO4 present in 0.500 L of the solution.

Answer:

The coronavirus has RNA?

Explanation:

Coronaviruses are important human and animal pathogens and contain an extraordinarily long (27-31 kb) RNA genome. Its RNA synthesis involves complex mechanisms of regulation, similar to those of DNA viruses. In this treatise, mouse hepatitis virus (MHV) is used as a model for the discussion of the mechanism of viral RNA synthesis. We show that MHV RNA synthesis requires interactions of multiple RNA components, which are likely mediated by protein-RNA and protein-protein, as well as RNA-RNA, interactions. This virus also provides a unique example of a discontinuous transcription mechanism, which involves a trans-acting RNA component. Finally, study of the cis-acting signals for the various steps of RNA synthesis revealed an insight into the regulation of viral RNA synthesis. This discussion suggests that the regulation of RNA synthesis in coronavirus is more complex than previously thought possible for RNA viruses. Coronavirus RNA transcription and replication may serve as a paradigm of RNA synthesis for RNA viruses in general.

Answer:

glucose

Explanation:

Glucose is the product of photosynthesis that is required for cellular respiration, serving as an energy source converted into ATP. Option C is correct.

The product of photosynthesis that is also a requirement for cellular respiration is glucose. Photosynthesis uses sunlight, carbon dioxide (CO₂), and water (H₂O) to produce glucose (C₆H₁₂O₆) and oxygen (O₂). While glucose is utilized as a source of energy during cellular respiration, oxygen is also involved in this process but is not considered a product of photosynthesis that is used in cellular respiration.

Glucose is the crucial link between these two processes, serving as the energy source that cellular respiration converts into ATP (adenosine triphosphate), the energy currency of the cell.

Hence, C. is the correct option.

Final answer:

Proteins in food are broken down into amino acids through chemical digestion, a process that takes place mainly in the small intestine with the help of enzymes. This is different from mechanical digestion, which physically breaks down food without changing its chemical composition. The resulting amino acids are then absorbed in the small intestine.

Explanation:

Proteins in foods are broken down into amino acids through the process of chemical digestion. This process involves the reduction of complex proteins into their chemical building blocks, amino acids, which can then be absorbed into the bloodstream to nourish the cells of the body. Most of chemical digestion occurs in the small intestine, particularly in the duodenum, where enzymes break down proteins. It is important to differentiate this process from mechanical digestion, which refers to the physical breakdown of food into smaller pieces through actions such as chewing, without altering the chemical composition of the food.

The absorption of nutrients, primarily in the small intestines, follows digestion. The amino acids, once liberated from the proteins by chemical digestion, are absorbed through the walls of the small intestine and enter the bloodstream for distribution to the body's cells. This process is fundamental because proteins in the diet are not directly absorbed but must first be broken down into their constituent amino acids.

Enzymes blind

Emzymes increase

Explanation:

Enzymes are biological catalysts that are essential to the functioning of living things. They are able to adapt their structure in response to various circumstances, which allows them to perform catalytic tasks with flexibility.

One enzyme can catalyse a wide variety of processes, which adds to the metabolic flexibility. Through feedback mechanisms, enzymes give organisms the ability to control physiological circumstances and maintain homeostasis.

Enzymes increase reaction speeds by lowering activation energy barriers by precisely binding to particular substrates. Cells can function well thanks to this catalytic process.

Thus, on the contrary, enzymes reduce the activation energy, speeding up processes. Enzymes are dynamic organisms at the centre of biological processes that expertly direct molecular changes.

Answer:

81.3%

Explanation:

Step 1:

The balanced equation for the reaction:

This is shown below:

C3H8 + 5O2 —> 3CO2 + 4H2O

Step 2:

Data obtained from the question. This includes:

Mass of propane (C3H8) = 470 g

Actual yield of water (H2O) = 625 g

Percentage yield of water (H2O) =?

Step 3:

Determination of the mass of propane (C3H8) burned and the mass of water (H2O) produce from the balanced equation. This is illustrated below:

C3H8 + 5O2 —> 3CO2 + 4H2O

Molar Mass of C3H8 = (3x12) + (8x1) = 36 + 8 = 44g/mol

Molar Mass of H2O = (2x1) + 16 = 2 + 16 = 18g/mol

Mass of H2O from the balanced equation = 4 x 18 = 72g

From the balanced equation above,

44g of C3H8 was burned and 72g of H2O was produced.

Step 4:

Determination of the theoretical yield of H2O. This is illustrated below:

From the balanced equation above,

44g of C3H8 produced 72g of H2O.

Therefore, 470g of C3H8 will produce = (470x72)/44 = 769.09g of H2O.

Therefore, the theoretical yield of H2O is 769.09g

Step 5:

Determination of the percentage yield of water (H2O). This is illustrated below:

Actual yield of water (H2O) = 625g

theoretical yield of H2O = 769.09g

Percentage yield of water (H2O) =?

Percentage yield = Actual yield/Theoretical yield x100

Percentage yield = 625/769.09 x100

Percentage yield = 81.3%

Therefore, the percentage yield of water (H2O) is 81.3%

Final answer:

The percent yield of water produced during the combustion of propane is calculated as the actual yield divided by the theoretical yield, multiplied by 100. Using stoichiometry, it is determined to be 81.35%.

Explanation:

The question is about the percent yield of water produced during the combustion of propane. The formula to calculate percent yield is actual yield divided by theoretical yield, multiplied by 100. First, we must establish the theoretical yield of water in moles. Propane has a molar mass of approximately 44.1 g/mol, so 470 grams of propane is equivalent to approximately 10.657 moles (470g / 44.1g/mol). The balanced equation states there are 4 moles of water produced per mole of propane, which would yield 42.628 moles of water (10.657 moles C3H8 x 4 moles H2O). Since the molar mass of water is about 18.015 g/mol, we multiply the moles of water by its molar mass to find the theoretical yield in grams: 768.311 g (42.628 moles x 18.015 g/mol). With an actual yield of 625 grams, we can now determine the percent yield: (625g / 768.311g) x 100% = 81.35%. Therefore, the percent yield of water for the stove is 81.35%.

Answer:

A) Index Fossils

Explanation:

Index fossils are fossils used to define and identify geologic periods. Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.

Answer:

P = 995.6 atm

Explanation:

assuming ideal gas:

∴ Tst = 25°C ≅ 298 K

∴ V = 35.00 mL = 0.035 L

∴ molar mass CO2 = 44.01 g/mol

∴ mass CO2(g) = 62.76 g

⇒ mol CO2(g) = (62.76 g)*(mol/44.01 g) = 1.426 mol

∴ R = 0.082 atm.L/K.mol

⇒ P = RTn/V

⇒ P = ((0.082 atm.L/K.mol)*(298 K)*(1.426 mol)) / (0.035 L)

⇒ P = 995.6 atm

Answer:

The pressure of the carbon dioxide (CO2) gas is 0.913 atm

Explanation:

Step 1: Data given

Mass of carbon dioxide (CO2) = 62.76 grams

Molar mass of carbon dioxide (CO2) = 44.01 g/mol

Volume = 35000 mL = 35 L

Standard temperature = 273 K

Step 2: Calculate moles CO2

Moles CO2 = mass CO2 / molar mass

Moles CO2 = 62.76 grams / 44.01 g/mol

Moles CO2 = 1.426 moles

Step 3: Calculate the pressure

p*V = n*R*T

⇒with p = the pressure of the gas

⇒with V = the volume of the gas = 35 L

⇒with n = the moles of the gas = 1.426 moles

⇒with R = the gas constant = 0.08206 L*atm/mol *K

⇒with T = the temperature = 273 K

p = (n*R*T) / V

p = (1.426 * 0.08206 * 273) / 35

p = 0.913 atm

The pressure of the carbon dioxide (CO2) gas is 0.913 atm

The volume of the balloon after adding the extra argon gas is approximately 11.89 liters.

To determine the volume of the balloon after adding the extra argon gas, we can use the concept of the ideal gas law, which states:

PV = nRT

where:

-  P  is the pressure

-  V  is the volume

-  n  is the number of moles

-  R  is the ideal gas constant

-  T  is the temperature

Since the problem doesn't specify changes in pressure or temperature, we'll assume they remain constant. Therefore, the volume is directly proportional to the number of moles of gas ( [tex]V \propto n[/tex] ).

Initially, the balloon contains 2.51 moles of argon in 5.29 liters.

We can set up the proportional relationship:

[tex]\frac{V_1}{n_1} = \frac{V_2}{n_2}[/tex]

Given:

-  V₁ = 5.29  liters

-  n₁ = 2.51  moles

-  n₂ = 2.51 + 3.13 = 5.64  moles

We need to find  V₂ :

[tex]\frac{5.29 \, \text{L}}{2.51 \, \text{moles}} = \frac{V_2}{5.64 \, \text{moles}}[/tex]

Solving for  V₂ :

[tex]V_2 = \frac{5.29 \, \text{L} \times 5.64 \, \text{moles}}{2.51 \, \text{moles}} \\\\V_2 = \frac{29.8356 \, \text{L} \cdot \text{moles}}{2.51 \, \text{moles}} \\\\V_2 \approx 11.89 \, \text{L}[/tex]

Therefore, the volume of the balloon after adding the extra argon gas is approximately 11.89 liters.

Answer:

rolling a 7

Explanation:

Because to roll a 2 you'd need double one's and to roll a 7 you'd need 2 different numbers so you'd have a better chance of rolling 2 different numbers than rolling the same numbers.

If This Helped Please Mark Brainliest!!!

Rolling a total of 7 is more likely than a total of 2 when two dice are rolled because there are more combinations (six) that add up to 7 compared to only one combination that adds up to 2.

Rolling a total of 7 is more likely than rolling a total of 2 when two six-sided dice are rolled. To determine the probability of these outcomes, we must consider all possible combinations that each die can produce. The sum of 7 can be achieved with six different combinations: (1,6), (2,5), (3,4), (4,3), (5,2), and (6,1). On the contrary, the sum of 2 can only be achieved with one combination: (1,1).

Since a fair six-sided die has an equal chance of landing on any one of its faces, each combination above has an equal chance of occurrence. Therefore, the probability of rolling a sum of 7 with two dice is 6/36 (since there are 6 favorable combinations out of a total of 36 possible combinations when two dice are rolled), which simplifies to 1/6. Meanwhile, the probability of rolling a sum of 2 is only 1/36, because there is only one favorable combination.

Hence, rolling a total of 7 has a higher probability than rolling a total of 2, since 1/6 is greater than 1/36.
