KCl is neutral because KOH is a strong base and HCl is a strong acid
To determine if the salt is neutral, acidic or basic, determine how the salt was made, or from which acid and base it was derived. Once we have determined how the salt was made, determine if the acid and base are both strong, weak or one of each. If both are strong (e.g. NaOH + HCl), then the salt (NaCl) is NEUTRAL. If the base is strong and the acid is weak (KOH + HCN), then the salt (KCN) is BASIC. IF the base is weak and the acid is strong (NH3 + HCl), then the salt (NH4Cl) is ACIDIC. If both the base and the acid are weak (NH3 + CH3COOH), then then salt (CH3COONH4) will have a pH determined by which is stronger (the acid or the base) and this will depend on the Ka of the weak acid compared to the Kb of the weak base.
KCl is neutral because KOH is a strong base and HCl is a strong acid NaCN is generally basic because NaOH is a strong base and HCN is a very week acid. NH4NO3 is usually acid because HNO3 is a strong acid and NH4OH is a week base
CH3COONH4 is exactly neutral because both NH4OH ad CH3COOH are respectively week base and week acid. Moreover, the Ka of acetic acid is exactly equal to the Kb of NH4OH

Explanation:
Nuclear fusion produces more energy with less radioactive waste compared to nuclear fission process.
- In nuclear fission, a radioactive decay occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons with the release of energy.
- Nuclear fusion occurs when small atomic nuclei combines into larger ones with the release of a large amount of energy.
- Instability of a nuclide is enough to start up a nuclear fission reaction. In some instances, a heavy nuclide is bombarded with another nuclide.
- In nuclear fusion, the activation energy required to start up is very great.
Nuclear wastes emanating from nuclear fusion process is least compared to that of nuclear fission.
Nuclear fusion produces more energy compared to nuclear fission process.

Ductility is the ability of a material to be remoulded to a force applied to it without breaking.

Answer:
The answer to your question is Molarity = 0.41
Explanation:
Data
mass of KNO₃ = 76.6 g
volume = 1.84 l
density = 1.05 g/ml
Process
1.- Calculate the molecular mass of KNO₃
molecular mass = 39 + 14 + (16 x 3) = 101 g
2.- Calculate the number of moles
101 g of KNO₃ --------------- 1 mol
76.6 g of KNO₃ ------------ x
x = (76.6 x 1) / 101
x = 0.76 moles
3.- Calculate molarity
Molarity = 
Substitution
Molarity = 
Result
Molarity = 0.41
