To solve this problem, we will first see what is actually happening in this reaction.
Then we look at it with the help of the reaction and finally, we will analyze the final product.
So let's understand that the reactants are phosphonium and sodium hydroxide and by heating these we get phosphine gas, water, and sodium iodide.
The reaction is below :
PH4I+NaOH→PH3+H2O+NaI
So, this is the final reaction of the given half-reaction. So, the correct answer is phosphine gas.
So, the correct option is A.
Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): A typical unfertilized, angiosperm embryo sac at maturity is 8-nucleate and 7-celled.
Reason (R): The egg apparatus has 2 polar nuclei.
In the light of the above statements, choose the correct answer from the options given below:
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
