1. How much heat is required to heat 22 grams of Aluminum from 15 °C to 49° C

Which statement is true about ionic compounds?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

How does the motion of particles in a gas change as the gas cools
