Answer:
its letter b
Explanation:
it represents the spectrum of stars
(3) the water to the ice cubes
This is so because the ice cubes are colder compared to their surrounding objects.
They absorb the heat from the water, cooling it, therefore vanishing(melting).
Answer:
This is a tricky one because this person was a massive part of your life, and now they're not. You're probably feeling hurt, confused, lonely and angry all at once. I have been here too and it's horrible so my thoughts are with you! For me, I had to make peace with it. It sounds silly but unfortunately there's not much we can do to try and win them back. If someone can go from being your best friend to all of a sudden hating you then they probably don't care about you as much as they should, and you're probably better off without them :) Seek people who actually care for you, and want to spend time with you. Friendships come and go, and as much as it hurts, if you can accept this and cherish your real friendships (the ones where you can go years without seeing eachother, but are there like a shot when you need them) then the pain should diminish. Good luck :)

Answer: The ![[OH^-]](https://tex.z-dn.net/?f=%5BOH%5E-%5D)
of a solution is 
M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of 
= 
Now put all the given values in the formula of molality, we get
pH or pOH is the measure of acidity or alkalinity of a solution.
According to stoichiometry,
1 mole of gives 1 mole of 
Thus 
moles of gives =
moles of
Putting in the values:
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[0.01][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5B0.01%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[OH^-]=10^{-12}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-12%7D)
Thus the of a solution prepared by dissolving 0.0912 g of hydrogen chloride in sufficient pure water to prepare 250.0 ml of solution is M
