Equations

Question 1

Metal + water →

Answer 1

Metal + water → Metal hydroxide + hydrogen

Question 2

Give the symbol equation for the reaction of :

Lithium and water

(-Then balance it)

Answer 2

Li + H₂O → LiOH + H₂

(note : it is always OH not HO)

balanced:

2Li + 2H₂O → 2LiOH + H₂

Question 3

Metal + Oxygen →

Answer 3

Metal + Oxygen → Metal oxide

Question 4

E.G.

Give the symbol equation for the reaction of :

Lithium and Oxygen

Then balance it

Answer 4

Li + O₂ → Li₂O

BALANCED:

4Li + O₂ → 2 Li₂O

note: remember equation (not necessarily balance ) so you can use for others as well

Question 5

Metal + Halogen →

Answer 5

Metal + Halogen → Metal halide
