Answer:
22.45g of Fe will be produced
Explanation:
The balanced reaction is:
Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)
<em>Where 1 mole of Iron (III) oxide reacts with 2 moles of Iron</em>
<em />
To solve this question we have to find the moles of iron (III) oxide. With these moles and the balanced reaction we can find the moles of iron produced and its mass:
<em>Moles iron (III) oxide -Molar mass: 159.69g/mol-</em>
32.1g Fe₂O₃ * (1mol / 159.69g) = 0.201 moles Fe₂O₃
<em>Moles Iron:</em>
0.201 moles Fe₂O₃ * (2mol Fe / 1mol Fe₂O₃) = 0.402 moles of Fe
<em>Mass Fe -Molar mass: 55.845g/mol-</em>
0.402 moles of Fe * (55.845g/mol) =
<h3>22.45g of Fe will be produced</h3>
Answer:
1.66 mins
Explanation:
Distance = 200 m
Speed = 2 m/s
Time taken =
secs = 1.66 mins
What's happening is the Mento is causing the carbonation in the bottle to release nearly all at once, causing the pressure in the bottle to increase drastically. This pressure causes the Coke to shoot out of the top, or if there's no hole the pressure makes the top shoot off or something to that effect.
Personally I like to drill holes in the top and use a little bit of wire to drop the Mento in. Then it looks really spectacular :D

Hope it helps.
Explanation:
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.
Sr - Strongium. i believe lol
