Answer: The positive and negative charges of the water molecule pull on the negative and positive ends of the ionic molecule to break them apart.
Explanation:
Ionic compounds dissolve in polar solvents such as water as like dissolves like. Ionic compounds are made up of ions which remain attracted by coloumbic forces.
Thus to separate the ions, the positive and negative charges of polar solvent pulls the opposite charges of the ionic compounds and thus break them apart. Thus the ionic compounds dissolve in water.
Answer:
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴
Explanation:
Alpha beta and gamma radiations are the examples of ionizing radiations. When an atom is an excited state and having high energy, the atom is in unstable state. The excess of energy is released by the atom to get the stability. The released energy is in the form of radiations which may include alpha, beta, gamma, X-ray etc.
Alpha decay:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴
Answer:
atoms
Explanation:
Given that,
Given mass = 13200 g
Molar mass of potassium = 39.0983 g/mol
Let there are n number of moles. It is equal to mass divided by molar mass. It is equal to :
Let there are x atoms in 13200 g of potassium (k). It can be calculated :
So, there are atoms.
Answer:
a)<em> Balanced equation:</em>
An equation is called balanced if there are same number and same type of atom on both sides of the equation.
b)<em>Reason:</em>
2KClO3--------2KCl + 3O2
Consider this equation in the reactants there are 2KClO3 and in the product there are 2KCl+3O2 . So reactants =products which is a case of balanced chemical equation .
