Answer:
This one represents calcium atoms that have lost two electrons >>Ca+2
C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
molar ratio of H2O to O = 6:8
<span>we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2
Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Hi!
The reason for reviewing and replicating work of other scientists is influenced by two factors listed in the answer:
1. An experiment may have had errors that the scientist did not recognize. <u>(unintentional) </u>
2. The results of individual scientists may be influenced by bias. <u>(intentional)</u>
<em>Personal motivations may often influence a scientist to manipulate the results to best suit his/her hypothesis, consequently leading to scientific fraud. </em>
While other options listed are elements of the scientific method, they are not the reasons behind the review and replication of a scientist's work by others.
Answer:
more genetic variation within a population usually enables more phenotypic variation.
Explanation:
Because natural selection acts directly only on phenotypes, Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
