Answer:
The factors on which the amount of energy absorbed by an endothermic reaction depends are the " physical state of the reactant and the difference in the potential energy of the reactant and the product".
Explanation:
In an endothermic reaction the factors that affects the reaction are the physical state of the reactant, which thus becomes the enthalpy. And the difference in potential energy of the reactant because if the sum of the potential energy is less than the sum of the potential energy of the product than the endothermic reaction will be positive and the reaction hence will be endothermic.

Answer: Mutations are important to the evolution of a species because is creates new DNA for a certain gene, creating a new allele.
Hope this helps!!! Good luck!!! ;)
Answer:
group 1 elements(hydrogen,sodium,etc)
Explanation:
bexause if noticed all the element in the same group have the same eletron in thr outer most shell for example the group 1 elements are said to have 1 outermost elect ron which make them react so the same
They're based on hydrogen.
Answer: 0.0014 atm
Explanation:
Given that,
Original pressure of air (P1) = 1.08 atm
Original volume of air (T1) = 145mL
[Convert 145mL to liters
If 1000mL = 1l
145mL = 145/1000 = 0.145L]
New volume of air (V2) = 111L
New pressure of air (P2) = ?
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1 = P2V2
1.08 atm x 0.145L = P2 x 111L
0.1566 atm•L = 111L•P2
Divide both sides by 111L
0.1566 atm•L/111L = 111L•P2/111L
0.0014 atm = P2
Thus, the new pressure of air when the volume is decreased to 111 L is 0.0014 atm
