Yes
No
What chemical unit is used to measure liquids?
Grams

Inches
Which law must be maintained during chemical reactions?
The Law of Laws
Natural Selection

The law of chemical reactions
Describe the difference between a chemical and physical reaction.
A chemical reaction can produce a new substance, physical reactions cannot
Chemical reactions concern colors, physical concern heart rate
Physical reactions depend on the periodic table, chemical reactions depend on photosynthesis

play doh
a type of clay
How do you describe the Law of Conservation of Mass/Matter?
It states that matter cannot be created or destroyed.
It states that energy cannot be created or destroyed.
It states that matter can be created or destroyed.
It states that sound can be created or destroyed.
