Which of the following statements is true about the role of oxygen in cellular respiration? it reacts with water. it is one of the ending compounds. it is one of the beginning compounds. it reacts with carbon dioxide.

cellular respiration the starting compounds are glucose and oxygen and the ending compounds are carbon dioxide, water, and energy.

C6H12O6+6O2-->6CO2+6H2O+ energy

Glucose (sugar)+oxygen--> Carbon Dioxide+ water+energy

so It is one of the starting compounds

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
