i have this huge chemistry packet with tons of problems and these six i just cant do please help!!!!!!!!!!!!!
quotes around # means the # is a subscript
1-Which is the correct mole ratio of K"3"PO"4" to KNO"3" in the chemical reation
Mg(No"3")"2"+K"3"PO"4" --> Mg"3"(PO"4")"2"+KNO"3"? (balance equation)
2-according to this chemical reation, which is the # of grams of Fe produced from 14 moles of H"2"?
Fe"3"O"4" (cr) + 4 H"2" (g) --> 3 Fe (cr) + 4 H"2"O (l)
3-how many grams of H"2"O will be produced if 750 grams of Fe are produced?
Fe"3"O"4" + H"2" --> Fe + H"2"O
4-How many grams of chlorine should be produced if 84.2 grams of aluminum chloride and 68.4 grams bromine are combined?
AlCl"3" + Br"2" --> AlBr"3" + Cl"2"
5-In a reation, 82.00 g of sodium reacts with 74.00 g of ferric oxide to form sodium oxide and iron metal. Calculate the mass of solid iron produced.
6-a 45.00-g sample of silver nitrate is mixed with 55.00 g of hydrochloric acid to form a white precipitate of silver chloride. after the solution is filtered and dried, a white precipitate of mass 33.50 g is collected.
a-determine the lomiting reactant
b-determine the theoretical yield of silver chloride
c-determine the percent yield of silver chloride
