C.)quartz. Quartz is forms not sedementary
3.9L
Explanation:
Initial volume = 25L
Final volume = 28.9L
The initial volume is the volume of the liquid without the metal in originally in the container. It is 25L
After adding the metal, the volume changes to 28.9L
Final volume = Initial volume + volume of metal
To find the volume of metal make it the subject of the expression;
Volume of metal = Final volume - initial volume = 28.9 - 25 = 3.9L
The volume of irregular solids are measured by immersing them in water. The change in volume gives their volume.
Sometimes the volume of water displaced is the volume of the solid.

Answer:
A.
Explanation:
Squeezing the bottle creates negative pressure inside the bottle because of the plastic's elasticity that will hasten the extraction of the carbon dioxide from the soda.
Answer:
Explanation: This reaction is called a synthesis reaction. This is because a synthesis reaction is when two or more reactants combine/react together to form a single product. The two reactants carbon (C) and oxygen (O2) reacted together to form one single product: carbon dioxide (CO2)
