Answer is (1) - less mass and greater penetrating power.
Alpha particle is a ₂⁴He nucleus while beta particles are electrons. Hence, the mass of alpha particle is greater than the mass of beta particle. But, the penetrating power is higher in beta particle than alpha particle. Alpha particles can be blocked by few papers but beta particles can go through those papers.
There are a number of ways to express concentration
of a solution. This includes molarity. Molarity is expressed as the number of
moles of solute per volume of the solution. The concentration of the solution
is calculated as follows:
Molarity = 2.0 mole / L solution
<span>2.0 mole / L solution ( 0.50 Liters ) = 1 mole solute</span>
<span>The correct answer is the third option. One mole of solute needed to make 0.50 liters of 2M solution.</span>
Answer:
Both molarity and formality express concentration as moles of solute per liter of solution. Formality is a substance's total concentration in solution without regard to its specific chemical form. ... The formality of a solution is defined as the number of formula mass of any solute dissolved in 1 litre of solution.
Electrolysis is a process, which allows us to break down a chemical compound into its elements, completing the balance by adjusting the number of atoms on both sides of the reaction is important because the number of electrons given up during oxidation must be the same as the number of electrons gained during the reduction.
<h3>What is electrolysis of water?</h3>
It is a process of oxidation and reduction of one or more elements that, through the induction of electric current, breaks down the water molecule (H2O), thus producing gaseous hydrogen and oxygen.
Oxidation and reduction processes occur simultaneously and never in isolation, which is why they are called redox reactions.
Therefore, we can conclude that electrolysis is a process where electrical energy will change to chemical energy where it is important that the number of electrons given up during oxidation is the same as the number of electrons gained during reduction.
