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
Answer: The gas generated by two antacid tablets has a smaller volume.
Explanation:
Since the antiacid is the limiting reagent, we know that the more tablets there are, the more gas there will be.
This means that there will be more gas generated by the four antiacid tablets when compared to the two antiacid tablets, which gives us that the gas generated by the two antiacid tablets has a smaller volume.
Each covalent H bond is nonpolar.
Nuclear transmutation is the conversion of one chemical element or isotope into another. In other words, atoms of one element can be changed into atoms of another element by transmutation.
