The mass of H₂O in the oceans is only about 0.02% of the mass of the Earth.

Given that seawater has a density of 1.025 gm/cm³ and that seawater is 96.5% H₂O. We want to calculate the mass of H₂O in the oceans. To calculate this, we first need to calculate the mass of seawater present in the oceans.

The mass of seawater present in the oceans is calculated as follows:Mass of seawater = volume of seawater × density of seawater Volume of the ocean is approximately 1.3 billion km³.Therefore, mass of seawater = volume of seawater × density of seawater= 1.3 × 10⁹ km³ × 1 × 10³ m³/km³ × 1.025 × 10³ kg/m³= 1.33 × 10²¹ kgNext, we want to find the mass of H₂O in the oceans.

To calculate this, we need to find 96.5% of the mass of seawater present in the oceans.

Therefore, the mass of H₂O in the oceans is:Mass of H₂O = 96.5% × mass of seawater= 96.5/100 × 1.33 × 10²¹= 1.28 × 10²¹ gTherefore, the mass of H₂O in the oceans is 1.28 × 10²¹ g.Finally, let us compare the mass of H₂O in the oceans to the total mass of the Earth. The mass of the Earth is approximately 5.97 × 10²⁴ kg, which is equal to 5.97 × 10²⁷ g. Therefore, the mass of H₂O in the oceans is only about 0.02% of the mass of the Earth.

The total energy absorbed by the sample is 34276m + 30075.2 J.

The heat of fusion is the amount of heat required to melt one unit of mass of a substance at its melting point without a change in temperature.

The heat of vaporization is the amount of heat required to vaporize one unit of mass of a substance at its boiling point without a change in temperature.

To calculate the energy absorbed by the sample, we need to know the mass of the sample and the temperature changes it undergoes. Assuming the sample starts as a solid at a temperature of -20°C, is heated to its melting point, melted, then heated to its boiling point, and finally vaporized, the calculations are as follows:

Energy absorbed to heat the sample from -20°C to 0°C:

Q = m * C * ΔT

Q = m * 1.56 J/g°C * (0°C - (-20°C))

Q = 31.2 * m J

Energy absorbed to melt the sample at 0°C:

Q = m * Hfus

Q = 107 J/g * 31.2 g

Q = 3338.4 J

Energy absorbed to heat the sample from 0°C to 100°C:

Q = m * C * ΔT

Q = m * 3.11 J/g°C * (100°C - 0°C)

Q = 311 * m J

Energy absorbed to vaporize the sample at 100°C:

Q = m * Hvap

Q = 854 J/g * 31.2 g

Q = 26636.8 J

Energy absorbed to heat the sample from 100°C to 200°C:

Q = m * C * ΔT

Q = m * 0.988 J/g°C * (200°C - 100°C)

Q = 98.8 * m J

Total energy absorbed:

Qtotal = 31.2m + 3338.4 + 311m + 26636.8 + 98.8m

Qtotal = 34276m + 30075.2 J

Answer:

The pH of the solution is approximately 1.093.

To solve this problem, we need to use the equation for the neutralization of an acid and a base:

acid + base → salt + water

In this case, the acid is HCl and the base is NaOH, so the balanced equation is:

HCl + NaOH → NaCl + H2O

According to the equation, 1 mole of HCl reacts with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of water. We can use this fact to determine how much of each reactant is used up in the reaction.

First, we need to calculate the number of moles of HCl and NaOH in the solution:

moles of HCl = concentration × volume = 0.249 M × 0.0407 L = 0.01015 moles

moles of NaOH = concentration × volume = 0.108 M × 0.0364 L = 0.00394 moles

Next, we need to determine which reactant is limiting. The limiting reactant is the one that is completely used up in the reaction, and determines how much product can be formed. To do this, we compare the number of moles of each reactant:

HCl:NaOH = 0.01015:0.00394 = 2.58:1

Since the ratio is greater than 1:1, we can see that HCl is in excess and NaOH is limiting.

Therefore, all the NaOH will react with the HCl to form NaCl and water:

NaOH + HCl → NaCl + H2O

The number of moles of NaOH used up is equal to the number of moles of HCl that reacts:

moles of NaOH used up = 0.00394 moles

The remaining moles of HCl that did not react is:

moles of HCl remaining = 0.01015 - 0.00394 = 0.00621 moles

To calculate the concentration of the NaCl solution formed, we divide the number of moles of NaCl by the total volume of the solution:

total volume = 40.7 mL + 36.4 mL = 77.1 mL = 0.0771 L

moles of NaCl = moles of NaOH used up = 0.00394 moles

concentration of NaCl = moles of NaCl / total volume = 0.00394 moles / 0.0771 L = 0.0511 M

Finally, we can calculate the pH of the solution using the formula:

pH = -log[H+]

Since NaCl is a salt of a strong acid (HCl) and a strong base (NaOH), it will not contribute to the pH of the solution. Therefore, the pH is determined by the excess H+ ions from the HCl. To calculate the concentration of H+ ions in the solution, we can use the following formula:

[H+] = moles of HCl remaining / total volume

[H+] = 0.00621 moles / 0.0771 L = 0.0804 M

pH = -log[H+] = -log(0.0804) = 1.093

The following could you add to increase the solubility of CaBr2 are NaNO3 and KOH. Option D and Option E are correct.

Solubility refers to the degree to which a substance is dissolved in a solvent to create a homogeneous solution. The solubility of a solute can be influenced by several variables, including temperature, pressure, and the chemical properties of the solute and solvent.

When an ionic compound, such as calcium bromide (CaBr2), is added to water, the solubility of the compound determines the degree to which it will dissolve.The solubility of calcium bromide (CaBr2) in water is determined by the type and amount of other substances that are present in the water. If you want to increase the solubility of calcium bromide, you can add a substance that is soluble in water and that can be ionized.

When the added substance dissolves in water, it ionizes and generates ions that can interact with the calcium and bromide ions in CaBr2 and increase the solubility. Sodium nitrate (NaNO3) and potassium hydroxide (KOH) are two substances that can increase the solubility of calcium bromide.

Therefore, the correct answer is D. NaNO3. and E. KOH.

Yes, More heat speeds up the dissolving reaction by supplying energy to break bonds in the solid. This is the most prevalent case in which an increase in temperature causes an increase in solid solubility.

As the temperature of the solution rises, so does the average kinetic energy of the solute molecules. As a result, the molecules are less able to stick together and disintegrate more easily. As a result, increasing the temperature increases the solubility of solid states.

Solute and solvent crystal structures must be identical. When the solvent and solute have the same valency, complete solubility occurs. A metal with a higher valency is more likely to dissolve a metal with a lower valency. The electronegativity of the solute and solvent should be comparable.

The no. of moles of \(CH_4\) remaining after the reaction is found to be 11.5 moles.

The no. of moles of a material equals the ratio of its given mass to the mass of one mole of that molecule in a chemical reaction.

The coefficients reflect the number of moles, not simply molecules, that react.

Stoichiometric coefficients are the numbers that come before the chemical formula of a molecule participating in a reaction. They assist us in determining the relative amounts or no. of moles of each reactant consumed and product created during a reaction.

\(CH_4 (g) + 2O_2 (g) \rightarrow CO_2 (g) + 2H_2O (g)\)

No. of moles of \(CH_4\) = 13.0 mol

No. of moles of \(O_2\) = 3.0 mol

Here \(O_2\) is limiting reagent because moles of \(O_2\) is less.

Thus, \(CH_4\) is in excess

1 mol \(CH_4\) = 2 mol \(O_2\)

x mol \(CH_4\) = 3 mol \(O_2\)

Moles of \(CH_4\) used = 3 x 1 / 2 = 1.5 mol

Here we have 13 moles of \(CH_4\),

Therefore,

No. of moles of \(CH_4\) left = 13 - 1.5 = 11.5

Result:

11.5 moles of \(CH_4\) will remain after the reaction.
