Students conduct an experiment: They placed Vinegar in a bottle and Baking Soda in a ballon...

They then placed the ballon on the bottle and proceeded to drop the baking soda into the bottle.

The students drew the following:

EXPLAIN BELOW THE PICTURE WHAT KIND OF CHANGE DID THEY OBSERVE AND THE PROOF.

Your

The balloon becomes inflated

Explanation:

The equation of the reaction between baking soda (sodium bicarbonate) and vinegar(ethanoic acid) is shown below;

NaHCO3 + HC2CH3O2 > NaC2H3O2 + H2O + CO2

The gas (CO2) evolved in the process leads to the inflation of the balloon dropped on the bottle in which the reaction is taking pace.

This observation provides evidence that a gas was really evolved in the reaction.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
