Answer:
8.81849
Explanation:
i believe the whole number would be this but usually i round to the second decimal point, i dont know if you could do that in chemistry tho
Na = +1
H = +1
O = -2
Total charge is 0:
1 + 1 + C + 3 x -2 = 0
C = 4
<span>a. Use PV = nRT and solve for n = number of mols O2.
mols NO = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols O2 to mols NO2. Do the same for mols NO to mols NO2. It is likely that the two values will not be the same which means one is wrong; the correct value in LR (limiting reagent) problems is ALWAYS the smaller value and the reagent producing that value is the LR.
b.
Using the smaller value for mols NO2 from part a, substitute for n in PV = nRT, use the conditions listed in part b, and solve for V in liters. This will give you the theoretical yield (YY)in liters. The actual yield at these same conditions (AY) is 84.8 L.

Answer:
3 Mg, 2 P, 14 O, 12 H
Explanation:
Without mincing words, let us dive straight into the solution for the problem above. This question is all about how how equations showing chemical reactions are being balanced.
From the question, we are giving the reactants: which are Mg(OH)2 and H3PO4 and in order to balance the reaction, the number of atoms in the reactants must be equal to the number of atoms in the products side of the reaction. Since, we have 3 Magnesium atoms, 2 Phosphorus atoms, 14 Oxygen atoms, and 12 Hydrogen atoms in the reactants side of the equation, the same number of atoms is expected in the products side.
