Answer:
measurements are important to do calculations to get correct results and without them scientists cannot form theories
Balanced chemical equation:
2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)
Explanation:
The correct chemical reaction is:
C₃H₆N₆ (l) + O₂ (g) → CO₂ (g) + H₂O (g) + N₂ (g)
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
Balanced chemical reaction:
C₃H₆N₆ (l) + (9/2) O₂ (g) → 3 CO₂ (g) + 3 H₂O (g) + 3 N₂ (g)
To have integer numbers we multiply the equation with 2 to obtain:
2 C₃H₆N₆ (l) + 9 O₂ (g) → 6 CO₂ (g) + 6 H₂O (g) + 6 N₂ (g)

Answer:
The answer to your question is 576 grams of FeO
Explanation:
Balanced chemical reaction
2Fe + O₂ ⇒ 2 FeO
Reactant Elements Products
2 Fe 2
2 O 2
Data
mass of FeO = ?
moles of Fe = 8
Excess Oxygen
Process
1.- Convert moles of Fe to grams
Atomic mass = 56 g
56 g of Fe ------------------ 1 mol
x ------------------ 8 moles
x = (8 x 56) / 1
x = 448 g of Fe
2.- Use the coefficients of the balanced reaction to find the grams of FeO.
Molecular mass of FeO = 2[ 56 + 16]
= 144 g
2(56) g of Fe ----------------------- 144 g of FeO
448 g ----------------------- x
x = (448 x 144) / 2(56)
x = 64512 / 112
x = 576 grams of FeO
