Taking into account the scientific notation, the result of the subtraction is -4.20689×10⁻².
<h3>Scientific notation</h3>
Scientific notation is a quick way to represent a number using powers of base ten, where the numbers are written as a product:
a×10ⁿ
where:
- a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
- n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.
<h3>Subtraction in scientific notation</h3>
When the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is -2.
Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 3.11×10⁻⁵= 0.00311×10⁻²
Taking the quantities to the same exponent, all you have to do is subtract what was previously called the number "a". In this case:
0.00311×10⁻² - 4.21×10⁻²= (0.00311 - 4.21)×10⁻²= -4.20689×10⁻²
Finally, the result of the subtraction is -4.20689×10⁻².

Hey :)
In a parallel circuit, a different amount of current flows through each parallel branch of the circuit.
In the series circuit, different voltage exists across each component in the circuit.
Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.
Hope this helps :)
P1V1T1=P2V2T2 Add 273 to convert degrees Celsius to Kelvin:
∴200×25/298=250×V2/273, ∴V2=200×25×273/298×250, ∴V2=18.32L
<h3>Where is the volume equation?</h3>
The basic formula for volume is length, breadth, and height, as opposed to length, width, and height for the area of a rectangular shape. The calculation is unaffected by how you refer to the various dimensions; for instance, you can use "depth" instead of "height."
<h3>What is chemistry using volume units?</h3>
Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.

1. 5 ethyl, 2 methyl octane
2. 1 ethyl, 2 methyl cyclopentane
3. 3,3,5,5- tetrafluoro heptane
4. 3,4-dimethyl hexene
5. 3,4-dimethyl cyclobutene
6. 3,5 diisopropyl cyclohexene
7. 3,3,4 trimethyl pentyne
8. 2,6 dibromo phenol
keep in mind that between 4-7, there could be #1 in front of the main name. for example with #4: 3,4-dimethyl-1- hexene. this honestly depends on the professor how he/she likes it. It is not necessary because if the number is not specified, it is assumed is #1
