Sodium/natrium is a metal from first column group so it should have one 1+ charge. Phosphate ion has 3- charge. That is why there 3 natrium ion for 1 phosphate ion when this molecule is dissolved in water. The ion formula would be:
(Na)

(PO

) ==> 3 Na

+ PO
Youve gotta multiply the percentages by the masses. Like here
(.8379)(51.94)
Answer:
<span>When identical particles pack in a simple cubic lattice, there is ONE particle per unit cell.
Explanation:
As we know that simple cube has eight corners and each particle at every corner is shared by eight cubic crystals. So it means that only </span><span>eighth </span>part of a particle is present at one corner of each cube. Therefore, each corner contain 1/8 particle, then all corners will contain 1/8 × 8 = 1 particle.
Answer:
the answer is 10
Explanation:
Al2 is 2 atoms by itself
(SiO3)2 is 8 because Si is a single atom and O3 is 3 oxygen atoms but because of the subscript outside of the parentheses it doubles and becomes 2 and 6 respectively
