Sample Questions

Question 1
In a chemical reaction, atoms of the reactants are best described as which of the following?
Completely destroyed and replaced by new atoms
Rearranged to form new substances with different properties
Only mixed together without any change in how they bond
Turned into energy so the products have no mass
Question 2

Ice melts into liquid water when heated
A solid dissolves in water but can be recovered by evaporation
Two clear liquids are mixed and a new solid forms that was not present before
A metal bar is cut into smaller pieces of the same metal
Question 3
A closed bottle contains a solid and a liquid that react to produce a gas. The total mass of the sealed bottle and contents is measured before and after the reaction. What result supports conservation of mass?
Mass after is greater because gas has extra mass that appears from nowhere
Mass after is less because gas has no mass
Mass stays the same because atoms are rearranged, not created or destroyed
Mass doubles because both a solid and a liquid were used
Question 4
Which statement correctly compares a physical change and a chemical change?
Physical changes always create new substances; chemical changes never do
Physical changes rearrange atoms into new substances; chemical changes only change shape
Physical changes may alter form or state without making a new substance; chemical changes produce new substances
Physical and chemical changes are identical because both involve heat
Question 5
Rust forms when iron reacts with oxygen in the presence of moisture. Rusting is classified as a chemical reaction mainly because:
The iron changes color only temporarily
A new substance with different properties forms from the iron and oxygen
The iron simply melts into a liquid
Water freezes on the metal surface
