Answer:
5.94
Explanation:
At equilibrium
⇒[CH3NH^+] = 0.130/2= 0.065 M
hence we can write that
x= concentration of H+ ions
⇒2×10^(-11)×0.065 = x^2
⇒x= 1.14×10^{-6}
therefore ph=log [H+]= log[ 1.14×10^{-6}]= 5.94
Answer:
Small marine animals produce a very hard skeleton made of calcium carbonate, which they extract from the seawater and combine CO2 for limestone.

The correct answer is A because a higher population count always results in the use of more resources (and thus less available in the end). This is why carrying capacities of ecosystems tend to get lower as population counts rise.

The correct answer is - natural gas.
The natural gas is the fossil fuel that releases the least amount of carbon dioxide in the atmosphere. It actually releases very little to none. The reason for that is that the natural gas is a fossil fuel which has the methane as its main ingredient. Even when used, it is not causing some serious pollution, instead the pollution comes from not well managed infrastructure and movement from one place to another of the natural gas. The biggest problem, pollution wise, comes from the leaking of the natural gas, when methane is released into the atmosphere.
