Answer:

A. yes

Explanation:

In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.

A diver dives off of a raft - what happens to the diver? The raft? How does this relate to Newton's Third Law?
sukhopar [10]

Answer:

Reaction Force!!

Explanation:

The diver moves “forward" and dives into the water. The raft moves "backwards” in the water because of the reaction force. The action force is the diver pushing off of the raft, and the reaction force is the raft pushing back on the diver (causing the diver to go forward and into the water).

Hope this helps you!!!

What is k in the rate law equation?
REY [17]

Answer:

B. A rate constant

Explanation:

The mathematical expression of rate law is given below,

Rate = K[A]m[B]n

This rate law show the relationship between the rate of chemical reaction and concentration of reactants.

In given equation [A] and [B] are molar concentration of reactants while K represent rate constant.

The value of K is specific for particular reaction at particular temperature,

m and n are represent exponents and determine experimentally. The value of K is not depend upon the concentrations of reactant but depend upon the surface area and temperature
