Answer: is considered as the limiting reagent for this reaction.
Explanation:
Limiting reagent is the reagent which limits the formation of the product.
Excess reagent is the reagent which is present in excess in a chemical reaction.
For the combustion of acetylene, the reaction follows:
By Stoichiometry,
5 moles of oxygen gas reacts with 2 moles of acetylene.
So, 81 moles of oxygen gas will react with = = 32.4 moles of acetylene.
As, the required amount of acetylene is less than the given amount. So, it is considered as an excess reagent and oxygen gas is the limiting reagent.
Answer:
Oxygen is the limiting reactant of this reaction.
Explanation:
2 moles of acetylene reacts with 5 moles of oxygen.
Then 37 moles of acetylene will react with :
of oxygen gas.
But only 81 moles of oxygen gas is present.
Then 81.0 moles of oxygen gas will react with:
of acetylene.
And still acetylene will remain after.
So, from the above calculation we cans see that oxygen is present in limiting amount which will limit the reaction.Hence, the limiting reactant of this reaction is oxygen.
Answer:
O-16 isotope is most likely to have the greatest abundance in nature.
Explanation:
Atomic mass of an isotopes of oxygen elements:
Average atomic mass of an oxygen atom = 15.994 amu
Isotope with the value of atomic mass closest to the average atomic mass of the oxygen atom will have the greatest abundance in nature. As it will be found in much more greater extent in nature.
Where as isotope which is least close to the average atomic mass will have less abundance in nature.
O-16 isotope is most likely to have the greatest abundance in nature.
15.995 amu ≈ 15.994 amu
Answer:
Explanation:
As the bacteria are capable of surviving in the hot temperatures as thermophiles they can speed up their respiration rate and hence, will produce more carbon dioxide and potentially accelerating the climate change within a region. The other prokaryotes can also become the significant contributors of the carbon output and these are those which are highly sensitive to the temperature. Methane oxidizing bacteria are also responsible for the contribution in carbon and nitrogen cycles. These bacteria converts the important greenhouse gas methane into carbon and nitrogen compounds like CO2 and NO2 − respectively. Thus methane can be considered as precursor of the temperature rise.
The answer will be A 313.6
