Answer:
1.8321 kg
Explanation:
The given 1 kg of coal contains 50% of the carbon atom by mass. Thus, mass of carbon in coal is 
Also, 1 kg = 1000 g
So, mass of carbon = 500 g
The formula for the calculation of moles is shown below:
Molar mass of carbon = 12.0107 g/mol
Moles of methanol = 500 g / 12.0107 g/mol = 41.6295 moles
Considering the reaction:
From the reaction,
1 mole of C react to form 1 mole of 
So,
41.6295 moles of C react to form 41.6295 moles of
Moles of = 41.6295 moles
Molar mass of = 44.01 g/mol
So, Mass = Moles × Molar mass = 41.6295 moles × 44.01 g/mol = 1832.1143 g
Also, 1g = 0.001 kg
<u>So, amount of released = 1.8321 kg</u>
We have that for the Question, it can be said that the mass of Ammonia is
Mass_a=3.162grams
From the question we are told
<em>Ammonia </em>gas has a <u>molar</u> mass of approximately 17 <u>grams </u>per mole. At 290k and 1.2 atm, a sample of <em>ammonia </em>has a volume of 3.7 L. In <em>three </em>to five sentences, explain how you can find the mass of the <em>ammonia</em>. Then, given R= 0.0821L.atm/mol.k, calculate the mass.
Generally the equation for the is mathematically given as
Now the mass of ammonia is
Hence the mass of Ammonia is
Mass_a=3.162grams

Answer: Change in a single nitrogen base in the DNA sequence will not have any significant effect on the organism.
So A
Explanation:
This is known as point mutation and it does not have any significant change in the protein and it is least harmful type of DNA mutation.
<span>It is necessary to critique a scientific argument before it is accepted, because the theory needs to be looked at every aspects and angles to test its solidity and validity. This is to make sure the theory is sound and will help any scientific investigations that relate to the theory. </span>
