Answer:
Carbon Dioxide
Explanation:
Carbon dioxide gets turned into oxygen
Answer:
1. Fe₂O₃ : Al = 1 : 2
2. Fe₂O₃ : Al₂O₃ = 1 : 1
3. Fe₂O₃ : Fe = 1 : 2
Note: The question is incomplete. The complete question is given below :
A thermite reaction releases large amounts of heat and light, resulting in the melting of the iron metal that forms during the reaction. The balanced chemical equation is given below: Fe₂O₃(s) + 2Al(s) ---> Al₂O₃(s) + 2Fe(l) Determine the correct mole ratios for the following substances, based on this chemical equation.
Explanation:
A thermite reaction is a highly exothermic reaction that occurs between a mixture of powdered aluminium and iron (iii) oxide.
The reaction is a redox reaction which produces aluminium oxide and metallic iron.
The heat given out in the reaction melts the iron formed. It is used to join railway tracks or cracked machine parts. The molten iron runs down between the tracks and welds them together.
The balanced equation of the reaction is given below :
Fe₂O₃(s) + 2Al(s) ---> Al₂O₃(s) + 2Fe(l) + Heat
The mole ratio of the reactant and products are as follows:
1. 1 mole of Iron (iii) oxide and 2 moles of aluminium are combined
Fe₂O₃ : Al = 1 : 2
2. 1 mole of aluminium oxide is produced from 1 mole of iron (iii) oxide
Fe₂O₃ : Al₂O₃ = 1 : 1
3. 2 moles of of iron are produced from 1 mole of iron (iii) oxide
Fe₂O₃ : Fe = 1 : 2
Answer:
Option B.
Explanation:
As any reaction of combustion, the O₂ is a reactant and the products are CO₂ and H₂O. Combustion reaction for ethane is:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
So 2 moles of ethane react with 7 moles of oxygen to make 4 moles of dioxide and 6 moles of water.
Then 2 moles of ethane will produce 4 moles of CO₂
Answer:
A water molecule can react with the carbonyl group of an aldehyde or a ketone to form a substance known as a carbonyl hydrate, as shown in the first reaction below. The carbonyl hydrates usually form a very small percentage of the molecules in a sample of a specific aldehyde or ketone.

I think the answer is choice b hope that helps u
