Answer:
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
Explanation:
So the chemical equation for this reaction would be SiO2 + 2C = Si + CO
so n(SiO2)=m(SiO2)/M(SiO2)=155400/60.08=2586.55 mol
n(C)=m(C)/M(C)=77400/12.01=6444.63 mol
So Carbon is in exes.
n(Si)=m(Si)/M(Si)=66200/28.09= 2356.71 mol
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
Depending on whether the cell is an animal cell or a plant cell, it could either be mitochondria or a chloroplast.
I believe the correct answer from the choices listed above is the first option. The number of hydrogen atoms that can bind to one carbon would be four. Tetravalent means it can form four bonds to other atoms. So, the answer should be four. Hope this answers the question.
Answer : Molar mass of the
is 159.7 g/mol.
Molar mass of the
is 101.96 g/mol.
Explanation:
Molar mass of
:

Molar mass = 
Molar mass of the
is 159.7 g/mol
Molar mass of
:

Molar mass = 
Molar mass of the
is 101.96 g/mol
Answer:
<h3>The answer is 2 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
N = 1.204 × 10²⁴ atoms of gold
We have

We have the final answer as
<h3>2 moles</h3>
Hope this helps you
