question

where is the gas formed during the chemical reaction of vinegar and baking soda and how can we see this

Hypothesis

The gas is formed as bubbles inside the mixture

Equipment

baking soda , sultanas, container, vinegar, and measuring spoons

Method

The vinegar is poured into the container.
The baking soda is sprinkled in the container
The sultana are the added.

Observation

Bubbles formed when the baking soda and vinegar mixed.
The sultanas traveled to the top of vinegar and then down.This repeated until the bubbles disappeared

Explanation

The sultanas moved to the top because the bubbles of carbon dioxide formed under the sultanas and pushed them to the top. At the top the bubbles popped and released gas causing the sultanas to fall. This process repeated until there were no more bubbles this proves that gas is formed as bubbles inside the mixture
