Natural gas is a fossil fuel that can be burned to heat our homes. The reactants in this chemical reaction are natural gas and oxygen. The products are water and carbon dioxide. The word equation below can be used to represent this reaction
natural gas + oxygen --> water + carbon dioxide
Which of the following is true about the mass of the reactants and the products?
The mass of the natural gas and oxygen will be less than the mass of the water and carbon dioxide.
The mass of the natural gas and oxygen will be greater than the mass of the water and carbon dioxide.
The mass of the natural gas and oxygen will be equal to the mass of the water and carbon dioxide.
The mass of the natural gas and oxygen will be destroyed to make water and carbon dioxide.

The carbon cycle demonstrates conservation of matter because:
Carbon atoms are created as materials move through the cycle.
Carbon atoms are destroyed as materials move through the cycle.
Carbon atoms are neither created or destroyed as materials move through the cycle.
None of these answers.
Photosynthetic plants affect the carbon cycle by:
Creating more carbon atoms.
Reducing the amount of carbon in the soil, reducing soil
Absorbing CO2 from the atmosphere, lowering atmospheric levels of carbon
None of the above; plants to do not affect the carbon cycle
Animals affect the carbon cycle by:
Creating more carbon atoms through cell division
Releasing CO2 into the atmosphere, increasing atmospheric levels of carbon
Consuming carbon, reducing the total amount of carbon that exists in the cycle
