Coal contains carbon and other elements. Carbon dioxide forms when coal burns in the presence of oxygen. Which of these is the best evidence that a chemical reaction occurs when coal burns?

Coal is made up of more than one element

The Law of Conservation of Mass states

that matter cannot be created or destroyed and that the mass of the products must equal the mass of the reactants

that matter exists in all states and reacts the same

that matter can only be changed into new substances by introducing a catalyst

that matter exists in the same state throughout any chemical change

What is a coefficient?

The large number in front of a chemical formula.

The small number on the right of the chemical symbol.

The number in between the chemical symbols.

The number behind a chemical formula.

At the end of chemical reactions, what is the total mass of the reactants compared to the total mass of the products?

the product is half the mass of the reactants

the mass changes depending on the reaction

_Na 3 PO 4+ _KOH ---> _NaOH + _ K 3 PO 4

1 Na 3 PO 4 +3 KOH ---> 3 NaOH + 1 K 3 PO 4

2 Na 3 PO 4 +2 KOH ---> 3 NaOH + 1 K 3 PO 4

1 Na 3 PO 4 +2 KOH ---> 2 NaOH + 1 K 3 PO 4

3 Na 3 PO 4 +3 KOH ---> 3 NaOH + 1 K 3 PO 4
