Describe the effect of water temperature on the amount of dissolved gases in water.

Answers

Answer 1

Polar solute dissolve in polar solvent and non polar solute dissolve in non polar solvent. Solubility is directly proportional o temperature. The solubility increases with temperature.

What is solubility?

Solubility shows the extent of solubility of a solute in solvent to make a solution. Solute is substances that is present in small amount. solvent is a substance that is present in large amount. Its SI unit is gram per litre or g/L.

Bond strength affect the solubility of a solute in solvent. weaker the bond strength is, more the solubility is. The weaker bond can be easily broken by water molecule.

The solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Therefore, solubility increases with temperature.

Answer 2

The solubility of gases in water decreases as the temperature increases, a phenomenon explained by the disruption of attractive forces between gas molecules and water due to added thermal energy. This inverse relationship has significant implications, including the effects of thermal pollution on dissolved oxygen levels in natural water bodies and the principles underlying decompression sickness in divers.

The relationship between water temperature and the amount of dissolved gases follows an inverse pattern. As the temperature of water increases, the solubility of gases decreases. This phenomenon can be explained by examining the nature of molecular interactions and the process of dissolution. When gases dissolve in water, they form attractive interactions with water molecules. Dissolving is generally an exothermic process for gases, meaning it releases heat. However, with the addition of heat to the system—which is what happens when water temperature rises—this thermal energy disrupts the attractive forces between gas molecules and water, leading to a decrease in the gas's solubility.

Temperature, solubility, and dissolved gases are intricately linked. For instance, in natural water bodies, an increase in temperature due to thermal pollution can lead to lower dissolved oxygen levels, impacting aquatic life. Moreover, the principles governing this relationship also explain phenomena such as the release of gases from a carbonated beverage upon opening. This scenario is a direct application of Henry's Law, which states that the solubility of a gas in a liquid at a specific temperature decreases as the partial pressure of that gas above the liquid decreases.

The practical implications of this phenomenon extend to various scenarios, including environmental impacts like thermal pollution and human activities such as diving, where understanding the solubility of gases is crucial to avoiding decompression sickness.

Chemical formula for beryllium oxide

Answers

Answer:

BeO

Explanation:

The chemical formula for beryllium oxide is BeO, following the combination of beryllium (Be2+) cations with oxide (O2-) anions in a 1:1 ratio, reflecting the stoichiometry of the compound and its ionic character.

The chemical formula for beryllium oxide is BeO. Beryllium oxide forms when beryllium, an alkaline earth metal with an atomic number of 4, combines with oxygen. Each beryllium atom releases two electrons, forming a Be2+ cation to Oxide2-. The resultant ionic compound, BeO, is a reflection of this 1:1 charge balance between beryllium and oxygen.

Beryllium compounds generally exhibit a significant degree of covalency. In particular, beryllium forms covalent bonds in different environments, as seen in compounds like beryllium hydride (BeH2) and basic beryllium acetate [tex](Be_{4} O(CH_{3}CO_{2} )_6)[/tex].

Although beryllium's tendency to form covalent bonds might suggest a preference for complex molecular structures, BeO is a simple, stable compound with each beryllium atom adopting an electron configuration similar to that of helium, the noble gas that precedes it in the periodic table.

5C + 6O2 = ? What will be the product of molecules formed from this equation?

Answers

Answer:

5C + 6O₂ → 5CO + 7/2 O₂

Explanation:

According to the question the reaction is between carbon and oxygen molecule . The reactant side was given as 5 moles of carbon reacting with 6 moles of oxygen molecules.   The chemical reaction between carbon and excess oxygen will form carbon dioxide but with limited oxygen it will form carbon monoxide.  

Now let us write and balance the actual chemical equation as required from the question. In limited oxygen the reaction will be

The reactant said 5 moles of carbon which is 5 atoms of carbon reacting with 12 atoms of oxygen.  The number of atoms of element on both sides of the chemical equation need to be balance . The balanced equation when oxygen is limited is written as

5C + 6O₂ → 5CO + 7/2 O₂

The product will be 5 moles of carbon monoxide and 3.5 moles of oxygen molecules(7 atoms) since the oxygen is limited . The carbon monoxide later reacts with more oxygen to form carbon dioxide.

Limiting reactant is the reactant that stops the reaction when it is completely consumed.  The product of the given reaction is Carbon dioxide.

Balanced Reaction:

A reaction in which the number of moles of atoms in reactants is equal to the number of moles of the atoms in the product.

The given reaction,

[tex]\bold{5C + 6O_2 \rightarrow 5CO_2 \\\\}[/tex]

Carbon is a limiting reactant that reacts with 5 oxygen molecules. Oxygen is the excess reactant present in a large amount in the atmosphere. Hence only 5 molecules of Carbon dioxide will be produced.

Therefore, the product of the given reaction is Carbon dioxide.

If you react 2.00 g of hydrogen completely using 15.87 g of oxygen to produce water, how much water (in grams) will you have?

WILL GIVE BRAINLIEST

Answers

Answer:

The amount (mass) of water we will have is 17.869 grams

Explanation:

The molar mass of hydrogen gas H₂ = 2.016 grams/mole

The molar mass of oxygen gas = 31.999 g/mol

Therefore, 2.00 g of hydrogen will give;

2.00/2.016 = 0.9921 moles of H₂ gas and

15.87 g of O₂ will give;

15.87/31.999 = 0.49595 moles

The reaction is as follows;

2H₂ (g) + O₂ (g) → 2H₂O (l)

Two moles of H₂ react with one mole of O₂ to produce two moles of H₂O

Therefore 0.9921 moles of H₂ will react with 0.9921/2 or 0.49595 moles of O₂ to produce 0.9921 moles of H₂O

From the above we note that all the H₂ and O₂ are completely consumed to form 0.9921 moles of H₂O

Molar mass of H₂O = 18.01528 g/mol

Number of moles = Mass/(Molar mass)

∴ Mass of H₂O = (Molar mass) × (Number of moles)

= 18.01528 g/mol × 0.9921 moles = 17.869 grams

Therefore the amount (mass) of water we will have = 17.869 grams.

What volume will 454.5 grams of Hydrogen gas occupy at 1.050 atm and 25.00 ℃? (Don’t forget Hydrogen gas is diatomic - H2.

Answers

Answer:

Explanation:

Considering the volume occupied by 454.5g of H2 at 1.050 atm and 25°C.

Likewise, using ideal gas equation.

pV = nRT

Answer: The volume occupied by the gas is 5295.1 L

Explanation:

To calculate the number of moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]

Given mass of hydrogen gas = 454.5 g

Molar mass of hydrogen gas = 2 g/mol

Putting values in above equation, we get:

[tex]\text{Moles of hydrogen gas}=\frac{454.5g}{2g/mol}=227.25mol[/tex]

To calculate the volume, we use the equation given by ideal gas equation:

PV=nRT

where,

P = pressure of the gas = 1.050 at m

V = Volume of gas = ?

n = number of moles of gas = 227.25 moles

R = Gas constant = [tex]0.0821\text{ L atm }mol^{-1}K^{-1}[/tex]

T = temperature of the gas = [tex]25^oC=[25+273]K=298K[/tex ]

Putting values in above equation, we get:

[tex]1.050atm\times V=227.25mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 298K\\\\V=\frac{227.25\times 0.0821\times 298}{1.050}=5295.1L[/tex]

Hence, the volume occupied by the gas is 5295.1 L

what kelvin temperature is equivalent to 35 degrees Celsius?

Answers

Answer:

308.15

Explanation:

To convert 35 degrees Celsius to Kelvin, you add 273.15, resulting in 308.15 Kelvin.

This conversion is straightforward because the size of one Kelvin is the same as one degree Celsius.

Hence, 35 degrees Celsius is equivalent to 308.15 Kelvin.To convert a temperature from degrees Celsius to Kelvin, you can use a simple formula: K = °C + 273.15. This formula takes advantage of the fact that the size of one Kelvin is identical to one degree Celsius; the only difference is their starting points.

For instance, to find the Kelvin equivalent of 35 degrees Celsius, you would calculate as follows:

Add 273.15 to the Celsius temperature: 35°C + 273.15 = 308.15 K.Therefore, the temperature of 35 degrees Celsius is equivalent to 308.15 Kelvin.

A solution with a ph of 2 has how many more protons in it than a solution with a ph of 4?

Answers

The solution with a pH of 2 has 100 times more protons in it than the solution with a pH of 4.

The pH scale is a logarithmic scale that quantifies a solution's acidity or alkalinity based on the concentration of hydrogen ions (protons) in it. Each unit on the pH scale reflects a tenfold change in hydrogen ion concentration. When compared to a solution with a pH of 4, a solution with a pH of 2 has a larger concentration of hydrogen ions. In particular, for every pH unit reduction, the concentration of hydrogen ions increases by a factor of ten. As a result, a pH 2 solution contains 102 (100) times more hydrogen ions than a pH 4 solution.

However, the potassium ion (K+) and the nitrate ion (NO3-) do not partake in the formation of the solid lead iodide, so they are omitted from the net ionic equation.

Explanation:

The question is asking about a precipitation reaction, which is when an insoluble compound forms in an aqueous solution. For the reaction given (2KI(aq) + Pb(NO3)2(aq) → PbI₂ (s) + 2KNO3(aq)), the insoluble compound that forms is lead iodide (PbI₂), which is why it is denoted with an (s) for solid. Soluble compounds break down into ions in aqueous solutions, meaning Pb(NO3)2(aq) becomes Pb²⁺ + 2NO3⁻, and 2KI(aq)  becomes 2K⁺ + 2I⁻. The products would then be K⁺ + NO3⁻ from KNO3(aq) and PbI₂(s), which stays unbroken because it is insoluble. Therefore, the complete ionic equation would be Pb²⁺(aq) + 2NO3⁻(aq) + 2K⁺(aq) + 2I⁻(aq) → PbI₂(s) + 2K⁺(aq) + 2NO3⁻(aq).

In such an equation, the ions that are on both sides of the equation (i.e., do not participate in generating the solid) are spectator ions and can be omitted to achieve the net ionic equation. For our reaction, the spectator ions are K⁺ and NO3⁻. Thus, they would NOT be present in the net ionic equation, but they would still be present in the complete ionic equation.
