Equation problems?
« on: November 06, 2016, 10:38:06 PM »
I am trying to do these review problems for a test tomorrow and I CANNOT figure them out.  ???

How many atoms of chlorine are in a 3.29g sample of iron (II) chloride?

What is the mass of sodium phosphate (in grams) if there are 8.71x1023 atoms of sodium present?

How many grams of hydrogen sulfide gas are required to burn 4.32g of iron (III) chloride? 3H2S + 2FeCl3 = Fe2S3 + 6HCl

How much hydrogen chloride will be produced in the exothermic reaction with 1.55g of hydrogen gas and 7.36g of chlorine gas?
