Answer:
Yes, Pb3(PO4)2.
Explanation:
Hello there!
In this case, according to the given balanced chemical reaction, it is possible to use the attached solubility series, it is possible to see that NaNO3 is soluble for the Na^+ and NO3^- ions intercept but insoluble for the Pb^3+ and PO4^2- when intercepting these two. In such a way, we infer that such reaction forms a precipitate of Pb3(PO4)2, lead (II) phosphate.

Answer:
Cu₂O.
Explanation:
copper = 7.298
copper oxide = 8.217
oxygen in copper oxide = .919 g
7.298 g of copper = 7.298 / 63.5 mole of copper
= .1149 mole of copper
.919 g of oxygen = .919 / 16 mole of oxygen
= .0574 mole of oxygen
ratio of mole of copper and oxygen
= .1149 / .0574 = 2
formula of copper oxide = Cu₂O.
