a) Sodium + oxygen = ?

When sodium reacts oxygen its forms sodium oxide as a product.

4Na(s)+O_2(g)\rightarrow 2Na_2O(s)

b) magnesium + fluorine = ?

When magnesium reacts with fluorine its forms magnesium fluoride as a product.

Mg(s)+F_2(g)\rightarrow MgF_2(s)

13)

a) 2HgO(s)\overset{\Delta }\rightarrow 2Hg(l)+O_2(g)

Decomposition of mercury(II) oxide on heating gives out mercury and oxygen gas.

b)2H_2O(l)\overset{Electricity}\rightarrow 2H_2(g)+O_2(g)

Nesterboy [21]

Answer:0.45L

Explanation:

molarity=0.15M

Mass=5g

No of moles=mass ➗ molecular mass

Molecular mass of KCL=39.0983x1+35.453x1

Molecular mass of KCL=74.5513

No of moles=5 ➗ 74.5513

No of moles=0.067

Volume in liters=No of moles ➗ molarity

Volume in liters=0.067 ➗ 0.15

Volume in liters=0.45L
