1. How can you use the chemical equation to explain what you observed when you added vinegar(acetic acid) to baking soda (sodium bicarbonate)?
2. How does a chemical equation helps to keep track of what happens in a chemical reaction.
Answers
ANS 1.The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects. Here is a look at the reaction between baking soda and vinegar and the equation for the reaction.
The overall chemical reaction between baking soda (sodium bicarbonate) and vinegar (weak acetic acid) is one mole of solid sodium bicarbonate reacts with one mole of liquid acetic acid to produce one mole each of carbon dioxide gas, liquid water, sodium ions, and acetate ions.
The reaction proceeds in two steps. The first reaction is a double displacement reaction, while the second reaction is a decomposition reaction.
The baking soda and vinegar reaction can be used to produce sodium acetate, by boiling off or evaporating all the liquid water.
ANS 2. Balanced chemical equations can be used to predict the relationship between the amounts of the reactants consumed and the amounts of the products formed in a chemical reaction. ... As a step toward the goal of the problem we might calculate the number of moles of oxygen consumed in the reaction.
