Answer:
I think it's nitrogen I'm not really sure..
When a compound containing C, H and O is completely combusted in air what reactant besides the hydrocarbon is involved in the reaction is Oxygen.
<h3>What is hydrocarbon?</h3>
A hydrocarbon is an organic molecule composed completely of hydrogen and carbon in organic chemistry. Group 14 hydrides include hydrocarbons. Hydrocarbons are often colourless and hydrophobic, with scents that are weak or exemplified by gasoline and lighter fluid. They exist in a wide range of molecular forms and phases, including gases (like methane and propane), liquids (like hexane and benzene), low melting solids (like paraffin wax and naphthalene), and polymers (such as polyethylene and polystyrene). Hydrocarbon refers to naturally occurring petroleum, natural gas, and coal, as well as their hydrocarbon derivatives and refined forms, in the fossil fuel industry. The primary source of energy on the planet is the combustion of hydrocarbons.

Electrons are shared in compound X and transferred in compound Y.
<h3>Further explanation </h3>
1. ionic bonding
Bonding that occurs due to electron transfer. Can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases
2. covalent bonding
Bonding that occurs due to shared use of electron pairs
The two bound atoms contribute their electrons to produce bonds
Generally occurs in non-metallic elements
So compound X = covalent bond (metal with metal) and compound Y= ionic bond(metal with non metal)
- Compound X : shared electron
- Compund Y : transferred electron
Answer:
6. this is because atomic mass 11 - atomic number 5 is equal to 6 neutrons.
