Answer:
you wont be able to ask any more questions until you answer some bc you get points from answering questions but you loose points when you ask them
Explanation:
<span>No of moles of Fe = Mass / Relative molar mass of Fe. So no of moles = 89.4/ 55.845 = 1.60. The. Chemical reaction is represented as follows. 4 Fe + 3 O2 which gives 2Fe2 O3 . This means that 4 atoms of Iron reacts with 3 atoms of Oxygen to produce Iron oxide. Hence 1.60*4 moles of Fe will need to react 1.6 * 3 moles of Oxygen to produce 2 moles of Iron oxide. Hence 4.8 moles of Oxygen will be required.</span>
Answer:
Júpiter and 60000 the are the awnsers
Since we are already given the balanced equation:
→ 
We can derive the molar ratios as: 1:2:1:1
That being said, we are given 0.172 moles of bromine (
), so it has a ratio of 1:1 with sodium bromide (
).
So we can take from that ratio, that when 0.172 moles of bromine are used, we are, in turn, going to get 0.172 moles of sodium bromide produced.
Answer:
114.4 grams of P₄O₁₀
Explanation:
P₄ + 5O₂ → P₄O₁₀
50 grams of P₄ are (50 g / 123.88 g/m) = 0.403 moles
Ratio is 1:1 so 0.403 moles of phosphorus can produce the same amount of P₄O₁₀.
Molar mass P₄O₁₀ = 283.88 g/m
0.403 moles . 283.88 g/m = 114.4 g
