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!
1) Chemical equation
<span>4C3H5(NO3)3(l) 12CO2(g) + 6N2(g) + 10H2O(g) + O2(g)
2) Molar ratios
4 mol C3H5(NO3)3 : 10 mol H2O
3) Convert grams of water into number of moles:
numer of moles = mass in grams / molar mass = 120 g / 18.0158 g/mol =
number of moles = 6.66 moles H2O.
4) use proportion and solve for x
4 mol C3H5(NO3)3 / 10 mol H2O = x / 6.66 mol H2O
=> x = 6.66 mol H2O * 4 mol C3H5(NO3)3 / 10 mol H2O = 2.66 mol C3H5(NO3)3
5) Convert </span><span>2.66 mol C3H5(NO3)3 into grams
mass in grams = molar mass * number of moles = 227.0995 g * 2.66 mol = 605.07 g
Answer: 605.07 g</span>
The oxidation number of Mn is 0. Details about oxidation number can be found below.
<h3>What is oxidation number?</h3>
Oxidation number is the hypothetical charge of an atom within a molecule.
However, when an atom exists independently as an element, the oxidation number of such element is 0.
The oxidation number is assigned to an atom in a element/compound. It can either be +, -, or 0 and it tells us if electrons are lost or gained.
Therefore, according to this question, the oxidation number of Mn is 0.
