The maximum number of moles of In that could be deposited at the cathode is 0.02 mole.
Given data:
number of ions, n=+3 ions
charge passed through the electrolytes,
Q = 0.06 F.
3 ions = 3 F
3 F ----------------------- 1 mole of the ion
0.06 F ---------------------- ? mole of the ion
no of moles = 0.06 F×1 / 3 F
no of moles =0.02 moles

Answer:
True
Explanation:
Molecular mass of :
Molecular mass of Ca + molevular mass of C + molecular mass of O × 3
40g + 12g + 16 × 3g
= 40g + 60 = 100g
Thus its true
We are given with the conditions of the weather balloon and required to determine the volume of the balloon when the altitude is raised to 25,000 feet. We determine the number of moles through ideal gas law PV = nRT. Plugging to this equation, the number of moles is 1.1351 moles. We substitute this with another set of conditions, volume is 47.46 liters.
Answer:
The side with lots of H+ and low pH
Explanation:
Because one of the feature of an acid is the ability to dissociate to H+.
And it has lower pH because the concentration of H+ is more than OH-
