Zinc does react with cold water - it just does so very slowly. Steam is water that is very hot and thus as with any chemical reaction, the heat gives the molecules more energy and so they react faster.
Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
Gold does not react with water or steam. i wouldn't totally agree with the above statment. There are 5 metals which don't not just 1...these are: .lead .copper .mercury .silver .gold
Zinc oxide ZnO
Yes zinc will react to form zinc nitrate and silver.
Zinc is unreactive to cold water, but will react with steam to give zinc oxide and hydrogen.

The react to form zinc sterate and water
Zinc oxide ZnO
2Al (s) + 3H2O(g) ---------> Al2O3 (s) + 3H2(g)
Yes zinc will react to form zinc nitrate and silver.
The products are zinc chloride and hydrogen.
Zinc does not react with titanium but it could be alloyed with titanium.
