What is the total amount of energy (in Joules) that it takes to melt and then heat 70.5 grams of water starting as ice at 0.00 degrees C and ending as liquid water at 55.60 degrees C? *

The first element on the periodic table of elements is carbon. a. true b. false

Which actions would increase the rate at salt dissolves in water? stir the water? crush the salt? use less water? heat the water? cool the salt

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.
