c
Explanation:
it is from crest to crest
The energy of an electron in a hydrogen atom is:
<span>E= (-2.179 x 10 ^-18 J)(1/n^2)
</span>where n is the principle energy level of the electron.
<span>
E= (-2.179 x 10 ^-18 J)(1/4)
</span><span>E= -2.179 x 10 ^-18 J
</span>E = -5.4 <span>x 10 ^-19 J</span>
The minerals?
when an acid reacts with a base it forms salts depending on the acids and bases reacted it will determine its formula
for example HCl + NaOH = NaCl + H20
hope that helps
