Ответ:
The kind of ion is X2+ ( where the ion is formed as a result of the loss of two valence electrons)
Explanation:
The ratio of ions of the element X to the phosphate ions is 3 to 2
So what we have as formula of these will be;
X3(PO4)2
Generally we have the phosphate ion formula as; PO4^3-
So for this formula above to be possible then the element x will have a formula of its ion X2+

Kevin’s weight may change between Planet X and Planet Y.
Explanation:
Mass is the amount of matter contained in an object. Gravity is Earth’s pull of a body towards its centre.
Weight (W) is product of the mass (m) of the object and the force of gravity (g) acting on the object.
W = mg
The force of gravity may change between Plant X and Planet Y, and thus Kevin’s weight may change between Planet X and Planet Y.
