By use of avogadros law which state that equal volume of gas at the same pressure and volume have the same number of molecules. The avogadros constant = 6.023 x10^23 for 1 moles what about 1.14 x 10^24
= 1.14 x 10 ^24 / 6.023 x 10^23=1.893moles
We know,
For given reaction, 
For , 2.41 moles of 
:
We know :
Hence, this is the required solution.
Answer:
B. ribosome
Explanation:
In the ribosomes, the codons get paired with anti codons to create a polypeptide or protein.
Answer is: <span>mass of calcium carbonate needed is 120 grams.
</span>Chemical reaction:
CaCO₃(s) → CaO(s) + CO₂(g)<span>.
</span>V(CO₂) = 27.0 L.
Vm = 22.4 L/mol.
n(CO₂) = V(CO₂) ÷ Vm.
n(CO₂) = 27 L ÷ 22.4 L/mol.
n(CO₂) = 1.2 mol.
From chemical reaction: n(CO₂) : n(CaCO₃) = 1 : 1.
m(CaCO₃) = 1.2 mol.
m(CaCO₃) = n(CaCO₃) · M(CaCO₃).
m(CaCO₃) = 1.2 mol · 100 g/mol.
m(CaCO₃) = 120 g.
Answer:
NH3 + CO2 + H2O -> NH4HCO3
This equation is already balanced
