Question

1. NaCl is sodium chloride
a. NaCl
2. HCl(aq) is hydrochloric acid
b. hydrochloric acid
3. P2O5 is diphosphorous pentoxide
d.diphosphorous pentoxide
4.NH4NO3 is ammonium nitate
c.NH4NO3
5.3Cu(NO3)2 + Zn3(PO4)2 -------> Cu3(PO4)2 + 3Zn(NO3)2
c.3,1,1,3
6.4NH3 + 5O2---------> 4NO + 6H2O
4 moles of NH3 react with O2 to gives 6 moles of H2O
2 moles of NH3 react with O2 to gives = 6*2/4 = 3 moles of H2O
b.3
7.b. double replacement
8. Cu + 4HNO3------------> Cu(NO3)2 + 2H2O + 2NO2
1 moles of Cu react with HNO3 to gives 2 moles of H2O
63.5g of Cu react with HNO3 to gives 2*18g of H2O
32g of Cu react with HNO3 to gives =2*18*32/63.5 = 18g of H2O
b. 18g
9. no of moles KCl = molarity * volume in L
                   = 3*0.5 = 1.5moles
a. 1.5 mol
10. b. CH3OH
11.PH = 1------3 range is strong acid
c. a strong acid
