Answer:
C2H4
Explanation:
cause the compound of ethylene is C2H4
Answer:
This is apparent charge, like water molecule is neutral having zero net charge
Explanation:
Simple and understood
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.
The percentage by mass of oxygen in the compound
find the total mass=( 1.900+ 0250 +0.850) = 3
the percentage mass mass of oxgyen/total mass x100
that is (0.850/3) x100=28.33%
