Question

When lithium metal is added to oxygen gas, lithium oxide is produced. Write the balanced equation and classify it

A Decomposition

B Single replacement

C synthesis

D Double replacement

Answer 1

Synthesis

Step-by-step explanation:

It cannot be decomposition because lithium oxide is being PRODUCED from the two reactants

It cannot be single replacement since there is only single elements there's nothing to replace each, you would end up with the same two elements.

It can't be double replacement since there is only single elements for each Li and O2

Synthesis works since together they form, or synthesize lithium oxide.

Answer 2

L + O2 —> LO. Therefore, since it’s 2 elements it will be a synthesis reaction. it’s C
