Answer:

D.

Explanation:

Although all of these answers are similar, it seems that all three are the answer. I am sorry if the answer ends up being B but I'm pretty sure the answer is D. Charles Darwin's evolution theory "evolved", get it, from the natural selection theory. The theory is described as "the process whereby organisms better adapted to their environment tend to survive and produce more offspring." However, some factors that effect natural selection are competition, selection and variation. I believe all three fit the answer and therefore I believe answer D is correct.

What is the concentration of H+ in a 2.5 M HCl solution?

Pavel [41]

Answer:

The concentration of H⁺ in a 2.5 M HCl solution is 2.5 M

Explanation:

As HCl is a strong acid and hence a strong electrolyte, it will dissociate as

HCl ⟶ H⁺ + Cl⁻

So, The concentration of H⁺ will be 2.5 M (same as HCl)

Thus, The concentration of H⁺ in a 2.5 M HCl solution is 2.5 M

Answer: 1.87 atm

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 2.50 atm

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas = 26.4 ml

$V_2$ = final volume of gas = 36.2 ml

$T_1$ = initial temperature of gas = $2.5^oC=273+2.5=275.5K$

$T_2$ = final temperature of gas = $10^oC=273+10=283K$

Now put all the given values in the above equation, we get:

$\frac{2.50\times 26.4}{275.5}=\frac{P_2\times 36.2}{283}$

$P_2=1.87atm$

The new pressure is 1.87 atm by using combined gas law.
