If water is added to 175 ml of a 0.45 m koh solution until the volume is 250 ml, what will the molarity of the diluted solution be?

C. chemical changeshope i : )

B.1 - hydrogren-1 can only mean there is 1 neutron. it's obvious there is 1 proton or else it wouldn't be hydrogen, so they wouldn't put a number after it unless they were indicating the number of neutrons

Ithink chemical bonding

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
