When one mole of Na3PO4.3H2O is heated extensively, three moles of water are released.

The water molecules in Na3PO4.3H2O are called molecules of water of crystallization. These molecules are not covalently bonded to the Na3PO4 molecule. They are only loosely attached to the substance.

Strong heating will drive away these molecules of water of crystallization to give three moles of water in the product.

Hence, when one mole of Na3PO4.3H2O is heated extensively, three moles of water are released.

Answer:

The correct answer is option b.

Explanation:

$H_2O\rightleftharpoons H^++OH^-$

The ionic product of water : $K_w$

$K_w=[H^+][OH^-]$

A pure water has equal concentration of hydrogen ions and hydroxide ions, hence neutral.

$K_w=[H^+][H^+]=[H^+]^2$

The ionic product of water at 283 K = $K_w=0.29\times 10^{-14}$

$K_w=[H^+]^2$

$0.29\times 10^{-14}=[H^+]^2$

$[H^+]=5.385\times 10^{-8} M$

The pH of the water at 283 k;

$pH=-\log [H^+]$

$=-\log[5.385\times 10^{-8} M]=7.26$

A pure water has equal concentration of hydrogen ions and hydroxide ions,So water will e neutral at this temperature also.

The correct answer is option b.

Answer:

Graph E matches description 3 (the car is accelerating).

Explanation:

When the graph increases, the line is turned up (graph E). So when something accelerates, it is going to increase. In this case, it would increase by speed.

jeka57 [31]

Answer:

$NH_3_{(aq)}+H_2O_{(l)}\rightarrow NH_4^+_{(aq)}+OH^-_{(aq)}$

Explanation:

Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations. Only the species which are present in aqueous state dissociate. So, the net ionic equation of aqueous solution of ammonia is shown below as:-

$NH_3_{(aq)}+H_2O_{(l)}\rightarrow NH_4^+_{(aq)}+OH^-_{(aq)}$
