Answer: the reaction rate decreases.

Fire is the result of a combustion reaction, which is the reactionof the organic matter with oxygen. The rate is proportional to amountof oxygen. The, when the amount of oxygen that reaches the organic matter decreases, the rate of combustion decreases too.

Answer is: The reaction rate decreases.

Balanced chemical reaction of burning log:

C(s) + O₂(g) → CO₂(g).

The reaction rate is the speed at which reactants are converted into products.

Reaction rate depends on concentration (amount) of oxygen.

If amount of oxygen decreases, reaction rate also decreases and vice versa.

"One has more oxygen atoms than the other" best distinguishes carbon dioxide from carbon monoxide

<u>Explanation</u>:

In both carbon monoxide and carbon dioxide, there is the presence of carbon and oxygen. However,they vary depending on the number of oxygen atoms.In carbon monoxide, there is the presence of one only  carbon and oxygen atom. Thus carbon monoxide is chemically represented as CO. Only about 0.2%ppm of carbon monoxide present in air.  carbon monoxide is toxic and causes death in human when not consumed is correct proportion.

Whereas in carbon dioxide, only one carbon atom,and two oxygen atom and hence chemically represented as co2.

Which place is a likely location for primary succession ​
ZanzabumX [31]
Primary succession occurs in an area that has not been previously occupied by a community. Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often- harsh environment become established first.
