A nonaqueous solution has a solvent that is not water. Which is an example of a nonaqueous solution?

Kay [80]

<span>The answer is paint. A dissoluble is a substance that breaks up a solute in the arrangement of an answer, and any dissoluble other than water is viewed as a non-fluid dissoluble. Some basic illustrations incorporate either, liquor, benzene, disulfide, carbon tetrachloride and CH3)2CO.</span><span />

For each of the following pairs of substances, determine which has the larger molar entropy at 298 K: (A) Br₂(l) or (B) Cl₂(g) (

irakobra [83]

Explanation:

Entropy is defined as the degree of randomness present in a substance. Therefore, more is the irregularity present in a compound more will be its molar entropy.

Hence, decreasing order to molar entropy in state of matter is as follows.

Gases > Liquids > Solids

In the first pair, we are given $Br_{2}(l)$ or $Cl_{2}(g)$ . Since, molar entropy of liquids is less than the molar entropy of gases.

Hence, $Cl_{2}(g)$ will have larger molar entropy as compared to $Br_{2}(l)$ .

In the second pair, we are given Fe(s) or Ni(s). More is the molar mass of a compound more will its molar entropy. Molar mass of Fe is 55.84 g/mol and molar mass of Ni is 58.69 g/mol.

Hence, molar entropy of Ni(s) is more than the molar entropy of Fe(s).

In the third pair, we are given $C_{2}H_{6}(g)$ or $C_{2}H_{4}(g)$ . As both the given species are gaseous in nature. So, more is the molar mass of specie more will be its molar entropy.

Molar mass of $C_{2}H_{6}(g)$ is 30.07 g/mol and molar mass of $C_{2}H_{4}(g)$ is 28.05 g/mol. Therefore, molar entropy of $C_{2}H_{6}(g)$ is more than the molar entropy of $C_{2}H_{4}(g)$ .

In the fourth pair, we are given $CCl_{4}(g)$ or $CH_{4}(g)$ . Molar mass of $CCl_{4}(g)$ is 153.82 g/mol and molar mass of $CH_{4}(g)$ is 16.04 g/mol.

Therefore, molar entropy of $CCl_{4}(g)$ is more than the molar entropy of $CH_{4}(g)$ .

In the fifth pair, we are given HgO(s) or MgO(s). Molar mass of HgO is 216.59 g/mol and molar mass of MgO is 40.30 g/mol.

Hence, molar entropy of HgO(s) is more than the molar entropy of MgO.

In the fifth pair, we are given NaCl(aq) or $MgCl_{2}(aq)$ . Molar mass of NaCl 58.44 g/mol and molar mass of $MgCl_{2}(aq)$ is 95.21 g/mol.

Hence, the molar entropy of $MgCl_{2}(aq)$ is more than the molar entropy of NaCl(aq).

What volume of hydrogen will be produced at STP by the reaction of 78.33 g of aluminum with excess water

nydimaria [60]

The balanced equation for the above reaction is
2Al + 6H₂O ---> 2Al(OH)₃ + 3H₂
stoichiometry of Al to H₂ is 2:3
number of Al moles reacted - 78.33 g / 27 g/mol = 2.901 mol
according to molar ratio
2 mol of Al forms - 3 mol of H₂
therefore 2.901 mol of Al - forms 3/2 x 2.901 = 4.352 mol

molar volume states that 1 mol of any gas occupies a volume of 22.4 L at STP
if 1 mol occupies 22.4 L
then 4.352 mol occupies - 22.4 L/mol x 4.352 mol = 97.48 L
volume occupied by H₂ is 97.48 L

What substance is not soluble in water, is derived from animal-based foods and synthesized by the body, and while circulating in

erma4kov [3.2K]

Answer:

D) saturated fat

Explanation:

Saturated fat -

It is a form of fat , where saturation is present , i.e. , presence of single bonds , it is a type of very unhealthy fat .

Butter , red meat , coconut oils and palm are rich in saturated fat , and are mostly in solid state at room temperature .

These fats often tends to be collected in the walls of arteries , and , can act as a restriction to the flow of blood .

Hence , the correct option for the given information of the question is saturated fat .
