1. release of energy as heat
2. release of energy as light
3. production of sound

4) Gas bubbles forming (unless water is boiling)
This is a chemical change. This is because it is a simple Acid - Base reaction; they neutralise one another to form a salt and water, along with carbon dioxide because baking soda is a carbonate.
An acid-base neutralization is not a specific reaction, but rather a category of chemical reactions. The two reactants are, as the name would suggest, an acid and a base. When they react, they form water, and a salt. Salt, in this sense, is used as a inclusive term for the ionic compound formed. It is not always table salt (NaCl).
An increase in Vmax suggest an increase in the amount of enzyme in the reaction. Also this increase in Vmax deceases the Km vaule, which means less substrate is needed.
This is a very violent reaction.
that reason is because when you mix some chemicals and colors you can get the property of paint or if you mess up the chemicals you could end up with something that is totally different that could be dangrous like a gas that can kill you which is bad for your health.
One observation that a chemical change has occurred is the formation of a new product. Another observation is the change in identity and composition of a substance.
No new products can be made in a chemical reaction. Only the reactants exchange or react with another element.
The reaction is:Ca + 2 H2O = Ca(OH)2 + H2- hydrogen gas is released- the reaction occur at room temperature
steam
Wouldn't suggest it. Permanent marker often contains chemical that aren't safe for the skin and may cause a reaction.
Phenol solution, or phenol directly from the manufacturer?If the phenol is in the form it comes in from the factory, no chemical test is necessary. Phenol is a white crystalline solid.If it's dissolved in water, the easiest test is pH. Phenol solution is more acidic than ethanol. So...whatever you use for a pH test will do ya.

there are different ingredients you need Corbin dioxide 10 times stronger than regular then normal and anything to color it i suggest food coloring and sodium iodide solution 2m and a graduated cylinder
