Answer: D) More moles of ions are present in a given volume of 0.10 M than in the same volume of 0.10 M NaCl.
Explanation:
A electrolyte is a solution that dissociates completely when dissolved in water. The ions act as good conductors of electric current in the solution.
More is the number of ions , more will be the conductance and hence the solution will be a better conductor of electricity.
0.10 M aqueous solution of is a better conductor of electricity as it dissociates to give three ions whereas 0.10 M aqueous solution of
dissociates to give two ions only.
Thus 0.10 M aqueous solution of sodium sulfate, , is a better conductor of electricity as more moles of ions are present in a given volume of 0.10 M
than in the same volume of 0.10 M
<u>Answer:</u> The student must add 2 infront of both and
to make the equation balanced.
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
For the given unbalanced chemical equation:
<u>On the reactant side:</u>
Atoms of H = 4
Atoms of S = 2
Atoms of O = 6
<u>On the product side:</u>
Atoms of H = 2
Atoms of S = 1
Atoms of O = 3
To balance the equation, a student must balance the atoms by adding 2 infront of both and
For the balanced chemical equation:
