It’s option c. When resources are limited competition will increase => one will survive while other dies=> population will decline.
Good luck

Answer:
pH = 5.22
Explanation:
As you can see, your initial concentration of sodium acetate (NaCH₃COO) is 0.02M (0.02mol /L). When you add HCl, the reaction is:
NaCH₃COO + HCl → CH₃COOH + NaCl.
If you add HCl, and final concentration of NaCH₃COO is 0.015M, the concentration of CH₃COOH is 0.005M.
You can know the pH of this solution using H-H equation:
pH = pKa + log {NaCH₃COO} / {CH₃COOH}
pH = 4.74 + log {0.015M} / {0.005M}
<h3>pH = 5.22</h3>
When it is at the top of its path (the side), the total energy is equal to just the potential energy since it isn't moving. This is m*g*h, where m is mass, g is acceleration due to gravity (~9.81 m/s/s), and h is the height above the bottom of the path.
At the bottom of the path, all the energy is now converted into kinetic energy. This is equal to the potential energy, and is also equal to 1/2 * m *v^2, where v is the velocity at the bottom of the path (which is all in the horizontal direction).
Answer:
There are 2 atoms in Chlorine(Cl)
and 3 atoms in Oxygen(O)
Explanation:
Answer:
the rule is V1/T1= V2/T2
so we convert the T1 from °c to kelvin
78+273.15= 351.15 k
1.60/351.15 = 0.425/T2
4.55 ×10-³ = 0.425/T2
then T2 = 93.40 kelvin
hence, we should decrease the temperature
