Law of Conservation of Mass

Question 5

Define the Law of Conservation of Mass

Answer 5

The total mass of substances taking part in a chemical reaction is conserved during the reaction

Question 6

In short terms what is the Law of Conservation of Mass?

Answer 6

Mass cannot be created or destroyed

Question 7

What must the atoms of reactants and atoms of products do?

Answer 7

They equal meaning balance

Answer 8

How many atoms of elements present in compounds

Question 9

What size are subscripts?

Answer 9

Small fonts

Question 10

Where is the subscript placed?

Answer 10

Directly after atom

Question 11

What is important to remember when writing subscripts?

It cannot be changed

Diatomic elements

Question 12

What are coefficients?

Answer 12

How many molecules of reactants and products present

Question 13

What size are coefficients?

Answer 13

Full size

Question 14

Where is the coefficients placed?

Answer 14

In front of reactant or product

Question 15

What is important to remember when writing coefficients?

Answer 15

It applies to the entire element or molecule. Affects first and second element

Question 16

What do we put between the reactant and product?

Answer 16

The yield sign

Question 17

What is the yield sign?

Answer 17

An arrow. NEVER an equal sign.

It means to produce

Question 18

What do you represent coefficients with when balancing?

Answer 18

A block

Question 19

What does the more atoms mean?

Answer 19

The bigger atomic number

Question 20

What is important to remember when drawing particle diagrams?

Answer 20

Key and using the same atom patterns

Question 21

When balancing which side do we start on?

Answer 21

Products

Question 22

What is important to remember when balancing word equations?

Answer 22

Always swop and drop with the products

Question 23

What does prove the periodic table makes use of the Law of Conservation of Mass mean?

Answer 23

At the end of balancing, multiply the final numbers by their atomic number. Add the final results and check if both sides are equal
