Aqueous solutions of barium nitrate and potassium phosphate are mixed. What is the precipitate and how many molecules are formed
2 answers:
Answer: The precipitate is and 1 molecule of Barium phosphate and 6 molecules of Potassium nitrate is formed.
Explanation: We are given Barium nitrate and Potassium phosphate , that will lead to the formation of Barium phosphate and Potassium nitrate.
As we know that these solutions are present in water, therefore we will obtain Barium phosphate as a precipitate because Barium phosphate is insoluble in water and Potassium nitrate is soluble in water. Thus the reaction is
To know how many molecules are formed at the end, we need to balance the above equation.
Balancing the equation, we get:
Thus, we get 1 molecule of Barium phosphate as a precipitate and 6 molecules of Potassium nitrate which is easily soluble in water.

Answer:
IV
Explanation:
The complete question is shown in the image attached.
Let us call to mind the fact that the SN1 mechanism involves the formation of carbocation in the rate determining step. The order of stability of cabocations is; tertiary > secondary > primary > methyl.
Hence, a tertiary alkyl halide is more likely to undergo nucleophilic substitution reaction by SN1 mechanism since it forms a more stable cabocation in the rate determining step.
Structure IV is a tertiary alkyl halide, hence it is more likely to undergo nucleophilic substitution reaction by SN1 mechanism.
