Answer:-
0.633 moles
Explanation:-
The first step to solving this problem is to write the balanced chemical equation.
The balanced chemical equation for this reaction is
3 CaCO3 + 2 FePO4 = Ca3(PO4)2 + Fe2(CO3)3
From the balanced chemical equation, we can see
3 moles of CaCO3 react with 2 moles of FePO4.
In the question we are told there are 1.9 moles of CaCO3.
So 1.9 moles of CaCO3 react with (2 moles x 1.9 moles )/ 3 moles= 1.267 moles of FePO4.
The question tells us there are 2.7 moles of FePO4.
So there is excess FePO4.
Thus our limiting reagent is CaCO3. It will determine how much Ca3(PO4)2 is formed.
From the balanced chemical equation, we can see
3 moles of CaCO3 gives 1 mole of Ca3(PO4)2
1.9 moles of CaCO3 gives (1 moles x 1.9 moles ) / 3 moles= 0.633 moles of Ca3(PO4)2.
0.633 moles of Ca3 (PO4)2 can be formed when 1.9 moles of CaCO3 react with 2.7 moles of FePO4
Answer:
Respiration process
Explanation:
Respiration is simply defined as the biochemical process where the body cells derive their energy from the combination of O₂ and food molecules, and in return liberates CO₂, along with some amount of H₂O and energy. This process elaborates on how the tissue cells help in shifting the O₂ from the exterior air into the cells and in return allows the CO₂ to be released outside.
This process is highly essential for an organism to survive. An organism cannot survive without carrying out this process.
