What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
How could you determine whether phenolphthalein remains in the residue of a titration reaction?
The easiest way is to add back some of the solution you were titrating. If phenolphthalein remains, it will react with the solution and change back to purple. Incidentally, phenolphthalein will always remain in the solution of the titration reaction - it changes color depending upon the pH of the solution, but the indicator itself is not affected by the titration reaction.
Is flavor change a chemical reaction?
Flavor change can be a result of a chemical reaction. When certain molecules in food or drink interact with each other or with the taste receptors on our tongue, it can alter the flavor. This can involve chemical reactions, such as the breakdown or formation of new compounds.
How could a chemist find out how much mass is given off as gas during a chemical change?

When you mix a pink powdered substance in water and mix it is that a chemical change?
Mixing is not itself a chemical change. There could be one occurring as a result, but nothing you described indicated any kind of chemical change.
What change could happen during a chemical reaction?
the chemical shall be changed
What are signs of a chemical reaction?
Some signs could be: *solids forming *bubbles *color change *temp. change
What star could support life?
No star itself could support life, but a planet around a star like our own and as far away as Earth may have some sort of life on it.

Could you change your attitude you should not only see life differently but life itself would come to be different?
'could we change our attitude ,we should not see life differently ,but life itself would come to be different.'
What do you have to do to release the energy of a fuel?
You have to produce some kind of reaction to make the fuel change state. This could be a nuclear reaction, or in the case of combustible fossil fuels it is a chemical reaction with oxygen
What are the signs of a physical reaction taking place?
There could be many possibilities depending of the reaction. Some of them are change in colour, odour, evolution of gases, formation of precipitate etc

Why do chemical properties change?
when something undergoes a chemical reaction, its properties may change. meaning the properties could be different than whhat they started off as.
How do you calculate the weight that a closed cylinder will support when suspended in water?
The cylinder will support, at neutral buoyancy, as much weight as the weight of water it could contain, less the weight of the cylinder itself.
Can Texas support itself if it secedes from the union?
I believe it could. We have a fishing, oil, wind energy, natural gas, and agriculture industry's.
