Consider the chemical equilibrium of a soap that is present in its aqueous solution. C17H35COONa(aq) mc017-1.jpg C17H35COO–(aq)
MAVERICK [17]

Answer : Option B) The equilibrium will shift to the left to such an extent that it leads to the precipitation of solid soap.

Explanation : The equilibrium will tend to shift to left because addition of sodium chloride salt will lead to precipitate the soap as a product. The volume increase in the sodium ions because of sodium chloride addition will generate the more amount of solid soap.

How much sulfur (in tons), present in the original materials, would result in that quantity of S)2
Olegator [25]
Sulfur reacts with oxygen to produce sulfur dioxide. That is for every mole of sulfur reacted, one mole of sulfur dioxide also is produced. With the given mole of sulfur dioxide, the amount of sulfur in mass is determined by multiplying the number of moles to the molar mass of sulfur (32 g/mol).
