Remember pH=-log(H ions). So it would be pH=-log(10^-7).
The correct answer is a the sun
Answer:
Your answer is D. It is the heat required to change a gram of substance from a liquid to a gas.
C. Cuz a tornado uses wind so the pressure must be high of it makes thing fly around.
The breakdown of NO3 in the day leads to more consumption of N2O5 in the day hence its concentration is greater at night than in the day.
<h3>What is equilibrium constant?</h3>
The equilibrium constant is a number that shows how much reactants are converted to products in a reaction. It is often shown as capital letter K in English.
Given the situation described in the question, we know that the concentration of N205 will be higher at night, because the decomposition of NO3(g) in the daytime will result in an increase in the rate of consumption of N2O5(g) to reform NO3(g).
