Heyy guys, so basically i need help with stoichiometric calculation I will give you 46 points just to answer all of these answers accurately with working out (ps ill mark you brainliest x), thanks. PLEASE HELPPP. I'm desperate x 3. What masses of ethanol and ethanoic acid would need to be reacted together to give 1 g of ethyl ethanoate?

C^2H^5OH + CH^3CO^2 H → CH^3CO^2C^2H^5 + H^2O

4. What mass of iron(III) oxide would need to be reduced to produce 100 tonnes of iron in a blast furnace?

Fe^2^O^3 + CO → Fe + CO^2

5. What mass of silver nitrate as a solution in water would need to be added to 5 g of sodium chloride to
ensure complete precipitation of the chloride?

AgNO^3(aq) + NaCl (aq) → AgCl (s) + NaNO^3(aq)

6. Copper(II) oxide reacts with sulphuric acid to produce copper(II) sulphate. If this is allowed to crystallise the formula of the crystals is CuSO 4 .5H 2 O. What mass of copper oxide would be needed to produce 100 g of crystals?

CuO + H^2O + H^2SO^4 = CuSO^4 .5H^2O

7. In the following reactions calculate the mass of precipitate formed from 20 g of the metal salt in each case.
a. ZnSO^4 (aq) + 2NaOH → Zn(OH)^2(s) + Na^2SO^4(aq)
b. Al^2 (SO^4 ) 3(aq) + 6NaOH → 2Al(OH)^3(s) + 3Na^2SO^4(aq)
c. MgSO^4(aq) + 2NaOH → Mg(OH)^2(s) + Na^2^SO^4(aq)
