Answer:

When a saturated solution at a high temperature is cooled, why is the solution separated as a solid? When a saturated solution at a high temperature is cooled, inter molecular space between the molecules of the solution decreases. As a result, no more solute can remain in a solution separating out as a solid crystal.

The balanced chemical equation for the formation of water from hydrogen and oxygen is given below:

2H2(g) + O2(g) → 2H2O(l)

The equation shows that 2 moles of hydrogen react with 1 mole of oxygen to form 2 moles of water.

The molar mass of hydrogen is 2.016 g/mol, while that of oxygen is 32.00 g/mol.

Therefore, the number of moles of hydrogen that reacts can be determined as follows:

n(H2) = mass/Mr(H2)n(H2) = 10.54 g/2.016 g/moln(H2) = 5.23 mol

Similarly, the number of moles of oxygen can be calculated as follows:

n(O2) = mass/Mr(O2)n(O2) = 95.10 g/32.00 g/moln(O2) = 2.97 mol

From the balanced chemical equation, it can be seen that 2 moles of water is produced for every 2 moles of hydrogen and 1 mole of oxygen that react.

Therefore, the number of moles of water that is produced can be calculated as follows:

n(H2O) = 2 x n(O2)n(H2O) = 2 x 2.97n(H2O) = 5.94 mol

The mass of water produced can be determined using the following formula:

mass = n(H2O) x Mr(H2O)

mass = 5.94 mol x 18.015 g/mol

mass = 106.97 g

Thus, 106.97 g of water will be formed if 10.54 g H2 reacts with 95.10 g O2.

Explanation:

disolvin rate is The rate at which a solute dissovles depends upon the size of the solute particles. Dissolving is a surface phenomenon since it depends on solvent molecules colliding with the outer surface of the solute.

saturation the degree or extent to which something is dissolved or absorbed compared with the maximum possible, usually expressed as a percentage.

changes in solubility  For many solids dissolved in liquid water, 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.

The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.

dilution is the making something weaker in force, content, or value.

Colligative properties of solutions are properties that depend upon the concentration of solute molecules or ions, but not upon the identity of the solute. Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.

To prepare a buffer solution with a pH of 5.59, 190.56ml of 0.1M NaOH should be added to 24.0ml of 0.1M Hb.

First, we can use the formula

ph = pka + log([base]/[acid])

to find the ratio of base to acid needed in the buffer. We know that the desired pH is 5.59 and the pKa of the acid (HB) is 4.54.

so,

5.59 = 4.54 + log(x)

where x is the ratio of base to acid

then we can solve for x,

x = \(10^{(5.59-4.54)\)

x = \(10^{(1.05)\)

x = 7.94

Now we know that we need 7.94 times more base than acid in the buffer solution. Since we have 0.1M of Hb and want to add 0.1M of NaOH, we can convert that ratio to volumes using the fact that the initial volume of Hb is 24.0 ml. So,

24.0ml x 7.94 = 190.56ml

So, we would need to add 190.56ml of 0.1M NaOH to 24.0ml of 0.1M Hb to prepare a buffer with a pH of 5.59.

Here, 3x10^23 molecules of water are equal to 0.5 moles of water.

There are many ways to find the number of moles of a compound, but to convert the number of molecules of water to moles of water, Avogadro's number needs to be known.

The formula used to find the number of moles is:

moles = (Number of molecules) / (Avogadro's number)

As Avogadro's number = 6.022 x 10^23 molecules/mole.

The given number of molecules is 3x10^23.

Putting the values in the above equation;

(3 x 10^23 molecules of water) / (6.022 x 10^23 molecules/mole) = 0.498 moles of water

Rounding off the value gives 0.5 moles of water.

Explanation:

To calculate the percent composition by mass of carbon in \(C_6H_{100}\), we need to determine the molar mass of carbon in the compound and divide it by the molar mass of the entire compound.

The balanced equation given indicates that for every 1 mole of \(C_6H_{100}\) burned, 6 moles of \(CO_2\) are produced. Using the molar masses of carbon and  \(C_6H_{100}\) , we can calculate the percent composition by mass of carbon.

The molar mass of carbon (C) is 12.01 g/mol. The molar mass of  \(C_6H_{100}\) can be calculated as follows:

(6 × 12.01 g/mol) + (1 × 1.01 g/mol) + (10 × 16.00 g/mol) = 162.10 g/mol.

To determine the percent composition by mass of carbon in  \(C_6H_{100}\) , we need to find the mass of carbon in 1 mole of  \(C_6H_{100}\) . Since there are 6 carbon atoms in the compound, the mass of carbon is:

(6 × 12.01 g/mol) = 72.06 g.

Now we can calculate the percent composition by mass of carbon:

(72.06 g / 162.10 g) × 100% ≈ 44.5%.

Therefore, the percent composition by mass of carbon in  \(C_6H_{100}\) is approximately 44.5%.

The correct statement is: An acyl halide reacts with an aromatic substrate in the presence of a Lewis acid catalyst to generate a cation that then loses a proton to a mild base to give the final product.

In a Friedel-Crafts reaction, the acyl halide acts as an electrophile, which reacts with an aromatic substrate in the presence of a Lewis acid catalyst. This generates a cationic intermediate known as a sigma complex. The sigma complex then undergoes deprotonation by a mild base (such as an acid-neutralizing agent like water or alcohol) to regenerate aromaticity and give the final product.

It is important to note that the reaction typically proceeds via electrophilic aromatic substitution, where the electrophilic acyl cation replaces a hydrogen atom on the aromatic ring, resulting in the formation of a substituted aromatic compound.

The true statement is that lambda O max increases as the number of conjugated bonds in a molecule increases. This is due to the “conjugated effect”, which explains why molecules with more conjugated bonds are better absorbers of light.

Conjugated systems absorb ultraviolet (UV) light. The wavelength at which light is absorbed, known as the lambda O max, is dependent on the number of conjugated bonds in a molecule. In general, the more conjugated bonds a molecule has, the higher its lambda O max.

When considering the true statement, it is clear that lambda O max increases as the number of conjugated bonds in a molecule increases. As the number of conjugated bonds increases, the molecule can absorb a higher energy of light, thus increasing the lambda O max. This phenomenon is known as the “conjugated effect”, which explains why molecules with more conjugated bonds are better absorbers of light.

In contrast, the statement that lambda O max increases as the number of conjugated bonds in a molecule decreases is false. As the number of conjugated bonds decreases, the molecule will be unable to absorb higher energy light and thus the lambda O max will decrease.

Finally, the statement that lambda O max is not affected by the number of conjugated bonds in a molecule is false. As discussed above, the lambda O max is directly related to the number of conjugated bonds in a molecule. A higher number of conjugated bonds results in a higher lambda O max, while a lower number of conjugated bonds results in a lower lambda O max.
