Question

Write fully balanced equations for the reactions of : [5]

i. Sulphur dioxide and water

ii. Sodium with water

iii. Iron with oxygen

iv. Aluminium and potassium hydroxide.

v. Iron (III) oxide and dilute sulphuric acid.​

Answer 1

Answer:

i ) Sulphur dioxide and water

SO2(g) + H2O(l) --> H2SO3(aq) .... The equation is balanced as written. ... SO2 is much like CO2

ii ) sodium with water

The question given to us is, Sodium + Water → Sodium hydroxide + Hydrogen. The balanced Chemical Equation is 2Na+2H2O→2NaOH+H2.

iii ) iron with oxygen

Therefore, the balanced equation for the reaction of iron and oxygen to produce iron (II) oxide is 2Fe(s)+O2(g)→2FeO(s) 2 F e ( s ) + O 2 ( g ) → 2 F e O ( s ) .

iv ) Aluminium and potassium hydroxide.

Al + KOH + H2O = K[Al(OH)4] + H2 | Chemical reaction and equatio

v ) Iron (III) oxide and dilute sulphuric acid

Fe2O3 + H2SO4 = Fe2(SO4)3 + H2O | Chemical reaction and equation
