catalysts

promoters

Term1/12
Is Dihydrogen monoxide an example of a nonpolar molecule
Definition1/12

Dihydrogen monoxide (H2O or Water) is not an example of a nonpolar molecule. It is a polar molecule.

Term1/12
Which process is often used to determine what coefficients to use to balance an equation
Definition1/12

Trial and error

Term1/12
According to the Law of Conservation of Mass in a chemical reaction the total starting mass of all the reactants equals the total final mass of all the products true or false
Definition1/12

False

Term1/12
Reaction such as a candle burning give off energy in the form of heat they're called
Definition1/12

Exothermic

Trishi! =)

Term1/12
Does The sharing of valence electrons between atoms indicates an ionic bond
Definition1/12

No
false

Term1/12
What is the name given to a reaction the gives off energy
Definition1/12

A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light

An example of an exothermic reaction would be the curing of concrete.

One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat.

There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".

Term1/12
Should you never change a subscript to balance an equation
Definition1/12

False

Term1/12
Is this true in a chemical reaction the substances that interact are called the products
Definition1/12

No. these are the reactants, the products are what are produced by the reaction.
