Why do all living things need oxygen?
a. to be used by cells to release energy from glucose
b. to be used by our cells for chemical reaction
c. for cellular respiration
d. all of the above
What is cellular respiration?
a. The process by which air is converted into energy.
b. The process by which glucose and oxygen is converted into energy.
c. When producers use sunlight and CO2 to make their own food.
d. When plants turn sunlight and oxygen into potential energy.
Which of the equation is a balanced equation for cellular respiration?
6CO2 + 6H2O →C6H12O6 + 6O2
C6H12O6 →6CO2 + 6H2O
C6H12O6 + 6O2 → 6CO2 + 6H2O
6O2 + 6H2O →C6H12O6 +6O2
Why are chemical changes different from physical changes?
a. A new substance is formed
b. Bonds are broken and new bonds are formed
c. atoms are rearranged into different molecules
d. all of the above
Which one of these is not a sign of a chemical change?
a. Change in shape
b. Bubbling
c. Change in temperature
d. precipitate is formed
Which of the following statements best defines the law of conservation of mass?
a. Mass cannot be created but it can be destroyed under extreme pressure
b. Mass cannot be conserved during a chemical reaction; a ittle bit of mass is always lost.
c. The mass of a closed system cannot change over time; mass cannot be created nor destroyed.
d. When added to a system, energy can destroy mass.
Which equation shows that a mass is conserved in a chemical equation?
