True. This is because specific heat depends on the heat capacity and the unit of mass. Mass, as we know is measured by grams, so this is a correct statement. 

Answer: True
shutvik [7]3 years ago

True, because molar heat capacity is the amount of heat required to raise 1 mol of a compound by 1 Kelvin. 1 mol of a compound has an equal number of grams to his molar molecular mass. Therefore, dividing it by the mass of 1 mol (aka molecular mass) is equal to amount of heat required to raise 1 gram of the substance by 1 degree Kelvin.

Please help 50 points A balanced chemical equation has _________ number of atoms for each element on both sides of the equation.
labwork [276]

Answer: must have THE SAME number of atoms for each element

Explanation:  Chemical equations must be balanced -- they must have the same number of atoms of each element on both sides of the equation. As a result, the mass of the reactants must be equal to the mass of the products of the reaction.

A gas is heated from 263.0 K to 298.0 K and the volume is increased from 24.0 liters to 35.0 liters by moving a large piston wit
Evgesh-ka [11]

Answer:

The answer to your question is   P2 = 0.78 atm

Explanation:

Data

Temperature 1 = T1 = 263°K                 Temperature 2 = T2 = 298°K

Volume 1 = V1 = 24 L                             Volume 2 = V2 = 35 L

Pressure 1 = P1 = 1                                  Pressure 2 = P2 = ?

Process

1.- To solve this problem use the Combined gas law

                          P1V1/T1 = P2V2/T2

-Solve for P2

                           P2 = P1V1T2 / T1V2

-Substitution

                          P2 = (1)(24)(298) / (263)(35)

-Simplification

                          P2 = 7152 / 9205

-Result

                          P2 = 0.777

   or                    P2 = 0.78 atm
