Help Chemistry!!!!!!!!!!! ( 10 points best answer)

The problem that I am having is the following:

Balance the equations below by writing coefficients greater than one in front of the formulas where needed. Identify the reaction type in the answer space to the left of the equation (synthesis (s), (decomposition (D), Single Replacement (SR) , or (Double Replacement DR)

_____ 1.) Al + HCl --> AlCl3 + H2 and an arrow going up

______2.) Fe2O3+ C --> Fe+ CO2 and arrow going up

______3.) S(s) + O2(g) --> SO3 (g)

______4.) N2+ H2-->NH3

______5.) H2O+ P2O5--> H3PO4

______6.)NH4NO2----> (there was a triangle below the arrow ) H2O + N2 and an arrow going up

______ 7.) Ba(NO3)2 + Fe2(SO4)3---> BaSO4 arrow going down + Fe(NO3)3

______ 8.) ZnCl2 + AgNO3 -->Zn(NO3)2 + AgCl arrow going down

______ 9.) Na2O + H2O--> NaOH

_______10.) NiCO3 + Al(OH)3--> Ni(OH)2+ Al2(CO)3

_______11.) Ca(ClO3)2--> (triangle below the arrow) CaCl2 +O2 an arow going up

_______ 12.) Mg+ H2O--> Mg(OH)2 + H2 and an arrow going up

Here are my some ogf my answers:


_____ 1.) Al + 3HCl --> AlCl3 + H2 and an arrow going up

______2.) Fe2O3+ C --> 2Fe+ CO2 and arrow going up

______3.) S(s) + O2(g) --> SO3 (g) synthesis

______4.) N2+ 3H2-->2NH3

______5.) H2O+ P2O5--> H3PO4

______6.)NH4NO2----> (there was a triangle below the arrow ) H2O + N2 and an arrow going up decomposition

______ 7.) Ba(NO3)2 + Fe2(SO4)3---> BaSO4 arrow going down + Fe(NO3)3 single replacement

______ 8.) ZnCl2 + AgNO3 -->Zn(NO3)2 + AgCl arrow going down

______ 9.) Na2O + H2O--> NaOH

_______10.) NiCO3 + Al(OH)3--> Ni(OH)2+ Al2(CO)3

_______11.) Ca(ClO3)2--> (triangle below the arrow) CaCl2 +O2 an arow going up

_______ 12.) Mg+ H2O--> Mg(OH)2 + H2 and an arrow going up synthesis

i hope that some of the answers are correct, the answers are in equations and some are next to

Please help me, and tell if some of the answers are correct and please tell the answers, I have more on my paper, but it would take me a long time to type all of them out., it;s because I have a test in chemistry to tommorow and I would like to practice and have the correct answers in front of me.
