Answer:
A) wrong. The molar is same so A is hevier
B)
Explanation:
Xg/mol × (same molar)= g
→ bigger molar bigger mass
The answer to this question is 1s^2.
The reaction is combination of hydrogen molecules and oxygen molecules and form water. So the oxygen and hydrogen required together is equal to the mass of the water formed.
Assuming that the solution is simply an aqueous solution
so that it is purely made of NaClO4 (the solute) and water (the solvent), then
I believe the dissolved species would only be the ions of NaClO4, these are:
Na+
ClO4 -
