The protons are equivalent to the atomic number, so we can determine that the element being expressed here is Magnesium. If you are ever stuck on what element you are finding your information from, just remember that the number of protons is the exact same as the atomic number in ANY situation :)
The charge of magensium is +2, with an atomic mass of 24. So A would be your answer :)
Answer:
A base.
Explanation:
Basic solutions give OH- ions.
Answer:
It depends on the number of significant figures you are changing to
Explanation:
6.02×1023=6158.46
1 sig fig = 6000
2 sig fig = 6200
3 sig fig = 6160
4 sig fig = 6158
5 sig fig = 6158.5
6 sig fig = 6158.46
When solving significant figures you have to consider the number after each number like in the case of changing to two sig fig the number following one is five and when the number is up to or greater than five you add a value of one to the number before it. But in a case where the number is less than five you just leave it like that like in the case of changing to one sig fig
