Oxygen can be produced in the chemistry lab at a low temperature if mixed with manganese dioxide, which acts as a catalyst in the reaction. the chemical equation for the production of oxygen using potassium chlorate is:

2kclo3 → 2kcl + 3o2

this equation represents both a and a(n) reaction.
a) combustion; decomposition
b) single replacement; combustion
c) combustion; oxidation-reduction
d) decomposition; oxidation-reduction

the solar system used to have much dust particles option no d

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.
