Do a chemical reaction produce heat and light?
Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
If a chemical reaction produces a gas how can that gas be captured in a test tube?
The flask should contain the reactants, and a bung should be put in the top of the flask. a tube should lead to a gas syringe.
How can you tell the difference between a phase change and when a chemical reaction produces a gas?
A phase change should not, in general, require more than one compound. A chemical reaction, by definition, will involve at least two compounds. The only "exception" would be a decomposition reaction, but in that case two different compounds would be formed so it's not really an exception.
Why should you balance chemical reaction?
we should balance a chemical equation so that both the sides of the elements and compounds are equal.
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
A change in matter that produces new substances is called?
Chemical change. References: Intro to Matter book.

Is a sunburn a chemical reaction or physical change?
Yes, the chemical reaction is your skin produces melanin (brown pigment) to help protect your skin from further damage from the UV rays. This is why humans have evolved to have dark skin in sunny tropical or sub-tropical areas. Your body also naturally produces vitamin D from the sunlight in the fat in your body under the skin and this is a chemical reaction too. So if you don't get out in the sun much you should take a vitamin D supplement or drink fortified milk or soymilk.
Should heat be added for a chemical reaction to take place?
If the reaction is endothermic in nature then heat should be added to it,otherwise all chemical reaction neddn't heat always.
What should be balanced in a chemical reaction?
Everything that is unbalanced...

To slow down a chemical reaction what should you add?
You should add an inhibitor. Have a great day!
How can you tell an acid from a base in a chemical reaction?
Most acids will have citrus in them. Like, lemon and oranges have citrus in them. Vinegar and baking soda will have a chemical reaction, should you mix them.
Why should chlorine bleach and ammonia never be mixed?
toxic chemical reaction
