Which of the following best defines molar heat capacity? group of answer choices the quantity of heat required to raise the temperature of 1 gram of a substance by 1°c the quantity of heat required to lower the temperature of 1 liter of a substance by 1°c the quantity of heat required to raise the temperature of 1 mole of a substance by 1k the quantity of heat required to raise the temperature of 1 gram of a substance by 1°f

The quantity of heat required to raise the temperature of 1 mole of a substance by 1K

Explanation:

As the temperature change is same in all scales of temperature.

The quantity of heat required to raise the temperature of a substance by one degree Celsius or one degree Kelvin or one degree Fahrenheit is called the heat capacity.

The quantity of heat required to raise the temperature of 1 gram of substance by one degree Celsius one degree Kelvin or one degree Fahrenheit is called as specific heat capacity.

The quantity of heat required to raise the temperature of 1 mole of substance by one degree Celsius or one degree Kelvin or one degree Fahrenheit is called as molar heat capacity.

Which reagent will be used up first? Thee answer is HCl.
We need to convert the amounts of the reactants into moles to see the limiting reactant.

48.2 g HCl ( 1 mol / 36.46 g) = 1.32 mol HCl

Since the ration is 1:4 then the limiting reactant is HCl. To react all of the MnO2 we need 3.44 mol HCl.

How many grams of Cl2 will be produced? 
We use the amount of limiting reactant since it will be used up first.

1.32 mol HCl (1 mol Cl2 / 4 mol HCl) ( 70.9 g Cl2 / 1 mol Cl2) =23.4 g CL2
