pls help me with this as fast as possible

Answer 1

Answer:

a) $Mg + O_{2} = Mg0$

b) $H_{2}SO_{4}$ + $Na$ = $HCO_{3} + Na_{2}SO_{4}$ $+ CO_{2} + H_{2}O$

c) $KOH + H_{2}SO_{4} = K_{2}SO_{4} + H_{2}O$

d) $PbO + O_{2} = PbO + O_{2}$

e) $CO_{2} + H_{2}O + light energy = C_{6}H_{12}O_{6} + O_{2}$

Hope this helps you.
