Oil spills are a very serious form of pollution. They severely affect marine biodiversity and coastal ecosystems. The table show

s methods that can be used to control oil spills.
A scientist wants to design a solution to control an oil spill. This solution should decrease the impact of the oil spill on the local biodiversity of the ecosystem. The solution should also be quick and effective but have minimal negative effects on the environment. Which of the following solutions would be best for the scientist to choose?

A. allowing natural processes to occur without any human intervention
B. using mechanical methods to collect the oil in one part of the ecosystem
C. using chemical methods to break the oil into smaller droplets
D. using bioremediation to speed up existing, natural oil degradation

the element carbon has two common isotopes: C-12 (12 U) AND C-13 (13.003355 U). IF THE AVERAGE ATOMIC MASS OF CARBON IS 12.0107
oksian1 [2.3K]

Answer:

The percent isotopic abundance of C- 12 is 98.93 %

The percent isotopic abundance of C- 13 is 1.07 %

Explanation:

we know there are two naturally occurring isotopes of carbon, C-12 (12u)  and C-13 (13.003355)

First of all we will set the fraction for both isotopes

X for the isotopes having mass 13.003355

1-x for isotopes having mass 12

The average atomic mass of carbon is 12.0107

we will use the following equation,

13.003355x + 12 (1-x) = 12.0107

13.003355x + 12 - 12x = 12.0107

13.003355x- 12x = 12.0107 -12

1.003355x = 0.0107

x= 0.0107/1.003355

x= 0.0107

0.0107 × 100 = 1.07 %

1.07 % is abundance of C-13 because we solve the fraction x.

now we will calculate the abundance of C-12.

(1-x)

1-0.0107 =0.9893

0.9893 × 100= 98.93 %

98.93 % for C-12.
