C. The answer is detroyed
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>
Lithium and nitrogen have the same electron energy levels, actually 2 levels.
Answer:
The correct option is;
c. Sound wave
Explanation:
The given options effect on mutation are given as follows;
a. Radiation
Radiation such as ultraviolet light and gamma radiation, which are electromagnetic waves, cause mutations by causing the formation of free radicals within an organism's cell resulting in the mutation characteristic effects
b. Smoking of tobacco has mutagenic effects due to the presence of several carcinogenic compounds in cigarettes
c. Sound wave is a form of mechanical wave and has no chemical effects on the chemistry of an organism and therefore does not cause mutation in cells
d. Chemical pollution can contain carcinogenic compounds that can cause mutations in the cells of organisms.
