Answer:
CnH2n+2 is the general formula for paraffins, also known as alkanes, which are saturated compounds with the general formula CnH2n+2, where n is the number of carbon atoms in the molecule. Methane (CH4), often known as C1, is the most basic of the alkanes and has the simplest structure. Normal paraffins (also known as n-paraffins or n-alkanes) are straight-chain molecules with no branches.
Explanation:
Alkanes are referred to as paraffins because they have a low affinity for a general reagent when heated. Alkanes, on the other hand, are non-reactive chemicals. When exposed to extreme circumstances, they have responses.
The atomic mass of the element = 24.309547
<h3>Further explanation</h3>
Given
Isotopes of Mg
Required
The atomic mass
Solution
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
The atomic mass of the element(Mg) :
= 23.98504 . 0.7870 + 24.98584 . 0.1013 + 25.98259 . 0.1117
= 18.876226 + 2.531066 + 2.902255
= 24.309547
The volume of 0.555M KNO3 solution would contain 12.5 g of solute iss 223 mL.
<h3>What is the relationship between mass of solute and concentration of solution?</h3>
The mass of solute in a given volume of solution is related by the formula below:
- Molarity = mass/(molar mass * volume)
Therefore, volume of solution is given by:
Volume = Mass /molarity * molar mass
Molar mass of KNO₃ = 101 g/mol
Volume = 12.5/(0.555 * 101)
Volume = 0.223 L or 223 mL
In conclusion, the volume of the solution is obtained from the molarity of solution as well as mass and molar mass of solute.

Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
Force=F= 5 N

Answer : The steps for balancing a redox reaction using half reaction method will include the following steps :
1) Write the basic ionic form of the reaction equation.
2) Divide the equation into two separate half reaction which will have oxidation half and reduction half reactions.
3) Balance the atoms present in each half of the reactions except O and H atoms in the reaction.
4) Balance the oxygen atoms in the reduction half of the reaction by the addition of two water molecules in the given conditions of the reaction.
5) Balance the charges present in both the half reactions.
6) The two halves of the equations reduction and oxidation are added to complete the overall reactions. After the addition of two reaction halves, cancel the same number electrons on both sides. The net ionic equation can be written after this step.
7) Finally, Verify whether the equation consists of the same type, number of co-efficients, and charges on both sides of the equation.
