Answer:
I don't really understand the first question but the second question answer is they do not live in the Artic Tundra because they are cold blooded and need hot habitats to survive.
Explanation:
The Arctic Tundra is cold and snakes need warm temps to survive because they are cold blooded.
Answer:
11·699
Explanation:
Given the concentration of hydroxide ion in the solution is 5 × 
M
Assuming the temperature at which it is asked to find the pH of the solution be 298 K
<h3>At 298 K the dissociation constant of water is
</h3><h3>∴ pH + pOH = 14 at 298 K</h3><h3>pOH of the solution = -log( concentration of hydroxide ion )</h3>
∴ pOH of the given solution = - log(5 × = -0·699 + 3 = 2·301
pH of the given solution = 14 - 2·301 = 11·699
∴ pH of the solution = 11·699
Hello!
First, HNO₃ dissociates in the following way:
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
Next, there is a neutralization reaction with Methylamine:
H⁺(aq) + CH₃NH₂(aq) → CH₃NH₃⁺(aq)
Finally, the formed methylammonium ion weakly dissociates in the following way:
CH₃NH₃⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + CH₃NH₂ (aq)
From this sequence of reactions, we can see that the resulting solution would be slightly more acidic than the initial one, as the buffer solution resists the addition of strong acid.
Have a nice day!
