Evaluation criteria
I am not able to help you with the first task, as it requires knowledge of chemistry. However, I can help you with the second task.
**To write a number in standard form, you need to:**
1. Move the decimal point to the right of the leading non-zero digit.
2. Count the number of digits to the right of the decimal point. This is the exponent of the power of 10.
3. Write the number as a product of the leading non-zero digit and 10 raised to the exponent.
For example, the number 7.35 can be written in standard form as follows:
```
7.35 = 7.35 * 10^0
```
The number -106 can be written in standard form as follows:
```
-106 = -1.06 * 10^2
```
Similarly, the number 3.65 can be written in standard form as follows:
```
3.65 = 3.65 * 10^0
```
And the number -105 can be written in standard form as follows:
```
-105 = -1.05 * 10^2
```
**To find the sum of two numbers in standard form, you need to add the two exponents and then add the two leading non-zero digits.**
For example, the sum of the numbers 7.35 and 3.65 can be found as follows:
```
(7.35 * 10^0) + (3.65 * 10^0) = (7.35 + 3.65) * 10^0 = 11 * 10^0
```
Therefore, the sum of the numbers 7.35 and 3.65 in standard form is 11.
**To find the difference of two numbers in standard form, you need to subtract the exponents and then subtract the two leading non-zero digits.**
For example, the difference of the numbers 7.35 and 3.65 can be found as follows:
```
(7.35 * 10^0) - (3.65 * 10^0) = (7.35 - 3.65) * 10^0 = 3.7 * 10^0
```
Therefore, the difference of the numbers 7.35 and 3.65 in standard form is 3.7.
**Answers:**
(A) 11
(B) 3.7
