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
The nucleus is where the protons and neutrons are found. the mostly space electron cloud is where the electrons are found, surrounding the nucleus.
The best word to fill the blank is "saturated". Hydrocarbons with only single bonds are saturated. These hydrocarbons are the deemed to be the simplest class. They are called saturated because each carbon is bonded to as many hydrogen as possible.
Answer:
picture not bright
Explanation:
please a brainliest for tge feedback
The liquid being blue in colour is qualitative data because it was observed not measured
