Answer:
An increase in temperature lead to more effective collisions between reactant particles
increase in the rate of a chemical reaction because the number of molecules with sufficient energy to react increases.
Explanation:
The difference I think is the fact one has DNA and the other doesn't.
Answer:

Explanation:
Hello,
In this case, given the reaction, we can directly compute the theoretically yielded grams of carbon dioxide, considering the 2:2 molar ratio between carbon monoxide (molar mass = 28 g/mol) and carbon dioxide (molar mass = 44 g/mol) and the initial reacting grams of carbon monoxide in excess oxygen:

Thus, as only 8 g were actually yielded, we compute the percent yield:

Best regards.
Its the straight segment C because its position is not going up or down, so it is not moving.
