Give the balanced equation for each of the following. The combustion of ethanol

Question

Give the balanced equation for each of the following. The combustion of ethanol (C_2H_5OH) forms carbon dioxide and water vapor. A combustion reaction refers to a reaction of a substance with oxygen gas. Aqueous solutions of lead(ll) nitrate and sodium phosphate are mixed, resulting in the precipitate formation of lead(II) phosphate with aqueous sodium nitrate as the other product. Solid zinc reacts with aqueous HCl to form aqueous zinc chloride and hydrogen gas. Aqueous strontium hydroxide reacts with aqueous hydrobromic acid to produce water and aqueous strontium bromide

Explanation / Answer

a ) balanced equation :

C2H5OH (l) + 3O2 (g) --------------------> 2CO2 (g) + 3H2O (g)

b) balanced equation :

3 Pb(NO3)2 (aq) + 2 Na3 PO4 (aq) --------------------> Pb3(PO4)2 (s) + 6 NaNO3 (aq)

c) balanced equation :

Zn (s) + 2 HCl (aq) -------------------> ZnCl2 (aq) + H2 (g)

d) balanced equation :

Sn(OH)2 (aq) + 2HBr (aq) ----------------------> SrBr2 (aq) + 2H2O (l)
