The theoretical yield of acetate is 2607 g. The actual yield of acetate is 1066.8 g. The percentage yield of acetate is 41%.
If 1 mole of vinegar contains 6.02 x 10^23 particles
x moles of vinegar contains 9.02 x 10^24 particles
x = 1 mole x 9.02 x 10^24 /6.02 x 10^23
x = 15 moles of vinegar
The reaction is as follows;
2HC2H3O2 + CaCO3 -----> Ca(C2H3O2)2 + H2O + CO2
Since 2 moles of vinegar reacts with 1 mole of carbonate
x moles of vinegar reacts with 16.5 moles of carbonate
x = 2 moles x 16.5 moles/ 1 mole
x = 33 moles of vinegar
We can see that the vinegar is the reactant in excess hence the carbonate is the limiting reactant.
Theoretical yield = 16.5 moles x 158 g/mol = 2607 g
Actual yield = 6.35 moles x 158 g/mol = 1066.8 g
Percent yield = 1066.8 g/2607 g × 100/1
= 41%

Answer:
Substance X has the highest temperature because its particles have more kinetic energy.
Explanation:
The temperature of a substance is an indicator of the average kinetic energy of the molecules of the substance.
In particular, the two quantities are directly proportional to each other, as shown in the equation:

where
KE is the average kinetic energy of the molecules
k is the Boltzmann's constant
T is the temperature of the substance
In this problem, we have a figure showing the movement of particles for 2 substances.
For substance X, the particles have long movement lines behind them: this means that they move faster, so their average kinetic energy is larger, and so the temperature of substance X is higher.
For substance Y, the particles have short movement lines behind them: this means that they move slower, so their average kinetic energy is smaller, and so the temperature of substance Y is lower.
Therefore, the correct option is
Substance X has the highest temperature because its particles have more kinetic energy.
