Answer:
the anode material is graphite(replaceable graphite rods).
The oxygen gas burns away the anode as Carbon dioxide therefore the anode must be replaced continuously.
Answer:
262.8 g
Explanation:
Molarity = 3.0M
Mass = ?
Volume = 2.40L
The relationship between these quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Molarity * Volume
Number of moles = 3 * 2.4 = 7.2 mol
Mass = Number of moles * Molar mass
Molar mass of HCl = 1 + 35.5 = 36.5 g/mol
Mass = 7.2 * 36.5 = 262.8 g
Because chemical energy is stored the chemical reaction takes place the stored chemical energy is released.
The correct answer among the choices is option A. The term that defines the following: grams of solute divided by 1,000,000 grams of solution is called ppm. This is one
way of expressing concentration. Parts per million is also equal to 1 milligram of solute per kilogram of
solution.
