Answer:
The relationship of pH and concentration of H+ ion is pH = -lg[H+]. So the concentration of H+ is 10^(-2). And [OH-][H+]=10^(-14). pOH + pH = 14. So the right answer is A.
The new combination is called a mixture.
In mixtures, since the substances are not chemically combined together, they still remain their own physical and chemical properties, and can be separated by simple physical methods such as filtration or distillation.
On the other hand, if the two or more substances are combined where they get new properties, the new combination will be called a compound. They cannot be separated by physical methods, but chemical methods such as heating or electrolysis.
It’s the elements that weigh the most are created when the events!

The relation between moles and mass is given by the formula:
# of moles = (mass in grams) / (molar mass)
So, given the molar mass of 18.02 and 0.025 mol, you can solve the formula for the mass of water in grams:
mass of water in grams = # of moles of water * molar mass of water
mass of water in grams = 0.025 mol * 18.02 g / mol = 0.4505 g of water.
Then, she is wrong.
