A compound contains carbon and hydrogen. This compound goes through a combustion reaction such that compound X is produced from the carbon atoms and compound Y is produced from the hydrogen atoms in the reactant. What are the compounds X and Y? Both are metal oxides.
Both are hydrocarbons.
X is methane, and Y is oxygen.
X is carbon dioxide, and Y is water.

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.

explanation:

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
