Answer:
28.1
Explanation:
Divide the percentage abundances by 100:
92.2% ÷ 100 = 0.922
4.7% ÷ 100 = 0.047
3.1% ÷ 100 = 0.031
multiply them by their corresponding mass number:
0.922×28 = 25.816
0.047×29 = 1.363
0.031×30 = 0.93
add them all together to get your final answer:
25.816 + 1.363 + 0.93 = 28.109
to one decimal place:
28.1
I hope that helps!!!
Answer:
Statements B (1-hexene will show an absorption at 1650cm-1 but cyclohexane will not)
C (both cyclohexane and 1-hexene will show C-H absorptions at about 2950cm-1)
are both true
This is more to do with Bioaccumulation of mercury, where the mercury is absorbed into the issue of animals, and so animals higher in the food chain consume a lot of tissue matter hence increasing mercury content in their system.
There are also cases when a negative change in entropy can lead to a spontaneous reaction. According to this equation, if the free energy, G, of the system is negative, then the reaction is spontaneous.
