What are 3 observations that would tell you that new products had been made in a reaction?
Change in color or appearance of the mixture. Evolution of gas or formation of bubbles. Generation of heat or cooling of the reaction mixture.
What were at least five observations you made that indicated a reaction had occurred in part a?
Color change in the reaction mixture. Formation of a gas, indicated by bubbles or fizzing. Change in temperature of the reaction mixture. Formation of a precipitate, where a solid appears in the mixture. Production of a new odor or change in smell of the reaction mixture.
What is a gas-evolution reaction?
A gas-evolution reaction is a type of chemical reaction that produces a gas as one of its products. This gas is usually released as a byproduct of the reaction and can sometimes be identified by observing bubbles forming in the reaction mixture. Examples include reactions that produce hydrogen gas, carbon dioxide, or oxygen.
What type of bubbles are produced in mixture of CuSO4 plus NaHCO3?
When copper (II) sulfate (CuSO4) and sodium bicarbonate (NaHCO3) are mixed together, carbon dioxide gas is produced. This gas forms bubbles in the solution, which are composed of carbon dioxide gas escaping from the reaction mixture.
What is an effervescent reaction?
An effervescent reaction is a chemical reaction that produces bubbles of gas within a liquid. This is often seen when an acid reacts with a base to form water and a gas, such as in the reaction of vinegar with baking soda to produce carbon dioxide gas.

Why do tiny bubbles form on and amongst DNA strands during extraction?
When the detergent/salt/DNA mixture is agitated, the detergent, along with some inadvertently trapped gas, forms bubbles, and these bubbles may stick to the DNA and the histone proteins. They are not formed by any chemical reaction.

What does orange juice do to vinegar?
Mixing orange juice with vinegar will create a chemical reaction that produces carbon dioxide gas. This gas will cause bubbles to form and the mixture to fizz. The acidity of both the orange juice and vinegar will also be enhanced when combined.
What happens when soap and hydrogen dioxide mixes with yeast?
When soap and hydrogen peroxide mix with yeast, the yeast enzymes break down the hydrogen peroxide into oxygen and water. This reaction produces bubbles of oxygen gas, which you may observe as fizzing or foaming. The soap helps to trap the gas bubbles, creating a frothy mixture.
When drain cleaner is added to water bubbles of hydrogen are produced Is what happens to form the bubbles when the cleaner is added a chemical or physical reaction?
If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.
How does the reaction between sodium bicarbonate and vinegar create a foaming effect?
When sodium bicarbonate (baking soda) reacts with vinegar (acetic acid), it produces carbon dioxide gas. This gas gets trapped in the liquid mixture, creating bubbles that form a foamy texture.
How does the temperature change when baking soda and vinegar are combined?
When baking soda and vinegar are combined, a chemical reaction occurs that produces carbon dioxide gas. This gas creates bubbles in the mixture, causing it to expand and rise. The temperature of the mixture may slightly increase due to the reaction, but it is not a significant change.
What do you see when a gas is being made in a reaction?
bubbles
