Answer: The fusion of hydrogen to form helium
Explanation:
The radius of a chlorine ion is larger than the radius of a chlorine atom because the effective nuclear charge decreases, therefore the inward force decreases, increasing the ionic radius.
Answer:
1+1=2 Unless this is a trick question. Then it's most likely 11.
Explanation:
Answer:
tiny crystals of the mineral quartz, which is made out of silica and oxygen
In order to calculate the number of atoms, we must first know the number of moles present. And
moles = (mass present) / (molecular mass)
Therefore, the moles of Mg present are
170 / 24 = 7.08
The number of atoms in a mole of substance is given by Avagadro's Number which is 6.02 x 10^23
Since there are 7.08 moles, there are:
7.08 * 6.02*10^23
= 4.26 * 10^24 atoms
