Answer:
A
Explanation:
A man has to give 23 and women has to also give 23.
A strong electrolyte like MgCl2 dissociates completely as per the following reaction:
As you can see, from 1 molecule of MgCl2 produces 3 ions on dissociation.
So, 1 mole of MgCl2 produces 3 moles of ions.
Now, Moles of MgCl2 = Volume x Molarity
= 0.04 x 0.345 [Change volume to Litres]
= 0.0138 moles
Now, total moles of ions = 0.0138 x 3 = 0.0414
Molar Mass: 300.0510 g/mol
<span>The best answer among
the choices is the first option. The chemical property of soda is that it is a
highly basic substance. It's chemical name is sodium carbonate. It is more
basic than sodium bicarbonate. Adding soda ash in a solution would increase the
pH of the solution.</span>
Through J.J. Thomson's creative mind, he proposed the "Plum Pudding Theory" which shows the scientific model of an atom wherein electrons are attached to the body of the atom as if it was like a raisin in a pudding. He also consolidates the properties of atoms at that time such as: electrons are negatively charge particles and and atom has neutral charge.
