These are the reactants in the chemical equation 2 h2 + 02 --> 2 h20

a. 2h2 + o2
b. 2 h2o

2H₂ + O₂

Are reactants in given chemical equation.

Explanation:

Chemical equation:

H₂ + O₂   → H₂O

Balanced chemical equation:

2H₂ + O₂   → 2H₂O

Tow moles of hydrogen H₂ react with one mole O₂  and produced two moles of water.

The given reaction completely hold the law of conservation of mas.

Reactants:

2H₂

O₂

Product:

2H₂O

Coefficient with reactant and products:

H₂      2

O₂      1

H₂O   2

its going to be mutualism cuz they both benefit from the relationship.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
