How do I write the chemical equations to the following descriptions (the answers are already known, I just need instructions on how to reach them):
a) 3 atoms of carbon combine with 4 molecules of hydrogen to produce methane (CH4) b) 7 molecules of hydrogen and 2 molecules of nitrogen gases react to produce ammoniac) 4 molecules of hydrogen and 5 molecules of chlorine react [ans: H2 +Cl2---> 2HCl]
What masses of calcium sulfate and phosphoric acid can be produced from the reaction of 1.0kg calcium phosphate with 1.0kg concentrated sulfuric acid (98% H2SO4 by mass)?
