How does the conservation of mass relate to baking soda and vinegar?
The mass remains the same before the reaction and after. A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass.
Does the mass change when vinegar reacts with baking soda in a plastic bag?
If Baking Soda (NaHCO3) is mixed with vinegar (C2H4O2) in an closed Ziploc bag, then the total mass will stay the same because the substances produced in the reaction aren’t going anywhere and cannot escape therefore there shouldn’t be any change.
Is mass gained or lost during a chemical reaction lab?
Mass is never lost or gained in chemical reactions. We say that mass is always conserved. In other words, the total mass of products at the end of the reaction is equal to the total mass of the reactants at the beginning. This is because no atoms are created or destroyed during chemical reactions.
Why does it matter how much vinegar and baking soda are added at a time in this experiment?
Adding vinegar to baking soda gives you an immediate reaction. Adding baking soda to vinegar, the reaction is delayed, but then fizzes the same amount. More vinegar is better. A 12 to 1 ratio of vinegar to baking soda caused a fizzing explosion!
What is the conclusion of baking soda and vinegar?
The experiment and result of it supported our hypothesis that the bubbles would float on top of the mixture of the baking soda and vinegar. It did this because when we combined the baking soda and vinegar it had a chemical reaction that produces carbon dioxide gas.
What are some examples of the law of conservation of mass?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
Which is the best example of law of conservation of mass?
12 g of carbon combines with 32 g of oxygen to form 44 g of CO2 is the best example of law of conservation of mass.
How is mass affected during a chemical reaction?
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. The carbon atom changes from a solid structure to a gas but its mass does not change. Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed.
Why does more vinegar and baking soda react?
They react because one is a base while the other is an acid. In our case, baking soda is sodium bicarbonate (a base) and vinegar is diluted acetic acid. When they react to release the OH and H to become water, they also release carbon dioxide.
