Question

Nitrogen plus Hydrogen produce Nitrogen Trihydride. sodium oxide combines with water to form sodium hydroxide. Sodium sulfate reacts with calcium nitrate to produce sodium nitrate and calcium sulfate. Zinc reacts with iron (III) chloride yielding zinc chloride plus iron. Hydrogen plus oxygen produce water. Sodium reacts with magnesium chloride yielding sodium chloride plus magnesium. Aluminum bromide plus chlorine yield aluminum chloride and bromine. Aluminum nitrate and sodium sulfide react to form aluminum sulfide and sodium nitrate

Explanation / Answer

Start writing the skeleton equations first .

Then start balancing the reactants with products , carefully identifying each element.

The balanced reactions are :

Ans 7.

Nitogen + Hydrogen = ammonia

N2 + 3H2 = 2NH3

ans 8 .

Sodium oxide + water = sodium hydroxide

Na2O + H2O = 2NaOH

Ans 9.

Sodium sulfate + aclcium nitrate = sodium nitrate + calcium sulfate

Na2SO4 + Ca(NO3)2 = 2NaNO3 + CaSO4

Ans 10.

Zinc + Iron (III) chloride = Zinc chloride + iron

3Zn + 2FeCl3 = 3ZnCl2 + 2Fe
