Answer:
atoms of isotopes of an element have different numbers of neutrons.
Explanation:
isotopes have the same number of protons, but different numbers of neutrons.
CO2 ~ 1 atom
N202 ~ 4 atom
CO ~ 2 atom
H2OS ~ 3 atom
B
Answer:
The correct answer is - option C. The equilibrium is shifted to the left and the value of K decreases.
Explanation:
The combustion of the methane produces water vapor, carbon dioxide when burns in presence of oxygen. This reaction also releases heat and light when combustion occurs.
CH4(g) +2O2(g)-----> CO2(g)+ 2H2O(g) + Heat
As this reaction releases the heat which means it is an exothermic reaction and as if the temperature increase, the equilibrium constant decreases, and as it decreases the equilibrium shifted to the left.
Thus, the correct answer is - option C.
