Exothermic, because it is releasing heat energy into its environment
In my point of view, the simple thing to do here is just to exchange the 3+ and the 2- and you will get:
Al2(CO3)3
The logic behind this is that when you have 2 Al^3+, it makes an overall charge of 6+. Additionally, when you have 3 CO^2-, it also makes an overall charge of 6- (because 3 X 2 = 6). Therefore, 6+ and 6- "cancelled" out, and you will have a neutral charge compound.
I hope you understand
<u>Answer:</u> The standard electrode potential of the cell is 0.62 V.
<u>Explanation:</u>
For the given chemical equation:
The substance having highest positive potential will always get reduced and will undergo reduction reaction.
<u>Oxidation half reaction:</u> ( × 3 )
<u>Reduction half reaction:</u> ( × 2 )
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
To calculate the of the reaction, we use the equation:
Hence, the standard electrode potential of the cell is 0.62 V.
Answer:
The freezing point depression can be calculated using the pure solvent freezing point and the molality of the solution.
At the freezing point, the vapor pressure of both the solid and liquid form of a compound must be equal.
The freezing point of a substance is the temperature at which the solid and liquid forms are in equilibrium.
To reattain equilibrium, the freezing point of the solute and solvent mixture is lowered relative to the original pure solvent.
True because any mass in a closed system will not add or lose mass
