What does a two direction arrow indicate in a chemical equation?
It indicates that the reaction can proceed in both directions. It could also mean that the reactions are in a dynamic equilibrium.
Which type of chemical reaction needs to absorb energy to proceed?
endothermic
What is it endothermic?
It is a chemical reaction which requires heat - possibly from the environment - to proceed.
A substance that enables a chemical reaction to proceed under different conditions?
catalyst.
How do you multiply negative mixed numbers?
Convert them to improper fractions and proceed. The answer will be positive.
How do chemical reactions proceed?
Atomic, and subatomic particles go to different atomic, and subatomic particles.
What would happen if there wasn't enough activation energy in a chemical change?
If the activation energy for a particular chemical reaction was not available the reaction cannot proceed. The chemical reaction cannot proceed without activation energy and cannot form products.
How do you subtract fractions with mixed numbers and like denominators?
Convert them to improper fractions and proceed.
How to add and subtract mixed numbers?
Convert them to improper fractions with common denominators and proceed.
A substance that enables a chemical reaction to proceed under the different conditions than otherwise possible?
Catalyst
How do an enzymes speed up chemical reactions in cells?
They lower the activation energy required for the reaction to proceed.
How do you add multiple mixed numbers?
Convert them to improper fractions, find a common denominator and proceed.
