Answer:
3.33 mol
Explanation:
1 g of oxygen is 0.062502343837894 mol
53.3 * 0.062502343837894
3.3313749265597505 mol
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.
Regards!
It's a chemical change because a new compound is formed
