The compounds in the reaction that shifts the equilibrium with the common ion effect are 
.
<h3>What is the common ion effect?</h3>
The equilibrium condition has an equal amount of reactant and products in the reaction.
The addition of ions same as product or reactant results in a change in the equilibrium of condition and shifts the equilibrium in opposite direction.
The given reaction is:
The addition of sulfate and hydrogen ions shifts the equilibrium.
Thus, the compounds that shift the equilibrium for the reaction are .

The correct option is:
The latent heat of vaporization of water is given by option D. 22,590J
Latent heat of vaporization:
Latent heat of vaporization is energy required to change 1 kg of liquid to gas at atmospheric pressure at its boiling point.
Also, Latent heat is the energy released or absorbed during a phase change.
Energy released during phase change is Exothermic process.
Whereas energy absorbed during phase change is Endothermic process.
Q=mL
Q= Latent heat
m= mass= 10 g
L= Latent heat of vaporization= 2,259 J/g
Putting the values in the above equation:
Q=10*2259
Q=22590 L

Answer:
The correct answer is option d.
Explanation:
It is defined as repeatable and consistent error associated with a faulty equipment. It a fixed amount of deviation of a measurement from the actual measurement.
These error usually caused by incorrectly calibrated instruments or by an incorrect use of the instruments.
For example: observational error , interference of environment etc.
The answer is (3) metallic. Cobalt is a transition metal, so it can't be covalent bonds, which bond non-metals, therefore eliminating choice 1 and 2. Ionic bonds are between metals and non metals, but solid cobalt does not have a non metal, eliminating choice 4 as well. Metallic bonds are bonds between metals, therefore the answer is (3) metallic.
