The statement in option B is not correct. B is the correct answer. This is because nuclear fission usually occur in large unstable isotopes, which are bombarded with high speed particles like neutrons, which make them to split into smaller particles. The statement in option A, C and D are true about nuclear fission.
Sound is not part of the electromagnetic spectrum because sound is not a type of energy wave sound is not a type of electromagnetic radiation sound does not have a wavelength sound does not have a frequency.

Answer:
3.37 m
Explanation:
<u>Number of moles of solute present in 1 kg of solvent is termed as molality</u>
It is represented by 'm'.
Thus,
Given that:
The mass of LiCl = 15.0 g
Molar mass of LiCl = 42.394 g/mol
The formula for the calculation of moles is shown below:
Thus,
Mass of the solvent = 105 g
Also, 1 g = 0.001 g
So,
Mass of water (solvent) = 0.105 kg
Molality is:
<u>Molality = 3.37 m</u>
Answer:
The equilibrium constant K is 0.1967
Explanation:
Chemical equilibrium is a state of a reacting system in which no observed changes over time, even though the reaction continues. It occurs in reversible reactions, where the rate of reaction of reagents to products is the same as that of products to reagents.
The chemical equation can be written as:
a A + b B → c C + d D
Where a, b, c, d are the stoichiometric coefficients of the reaction and A, B, C, D are the symbols or formulas of the different substances involved.
The equilibrium constant K can be defined as the ratio between the product between the concentrations of the products (in equilibrium) raised to their corresponding stoichiometric coefficients, and the product of the concentrations of the reactants (in equilibrium) raised in their corresponding stoichiometric coefficients:
In this case:
You know that:
Replacing:
Kc= 0.1967
<u><em>The equilibrium constant K is 0.1967</em></u>
