Which of the following exihibits highest solubility in $ H_2O $
Ammonia ($NH_3$) exhibits the highest solubility in water. This is due to the hydrogen bonding between the $NH_3$ molecules and $H_2O$ molecules. Ammonia has a lone pair of electrons on the nitrogen atom, which can form hydrogen bonds with water molecules, making it highly soluble.
The three important oxidation state of P are
Phosphorus (P) mainly exhibits three oxidation states: -3, +3, and +5. In the -3 oxidation state, phosphorus forms compounds like phosphine ($PH_3$). In the +3 oxidation state, it forms compounds such as phosphorus trichloride ($PCl_3$). In the +5 oxidation state, it forms compounds like phosphorus pentachloride ($PCl_5$) and phosphoric acid ($H_3PO_4$).
Which show maximum valency
P Shows + 5 valency.
Which oxide of N is obtained on heating ammonium nitrate at $ 250 ^\circ $ C
When ammonium nitrate ( ext{NH}_4 ext{NO}_3) is heated to about 250°C, it decomposes to form nitrous oxide ( ext{N}_2 ext{O}) and water. The reaction is as follows: $$ ext{NH}_4 ext{NO}_3 ightarrow ext{N}_2 ext{O} + 2 ext{H}_2 ext{O} $$
Which compound is related to haber’s process
Ammonia generally prepared by Haber's process
Which of the following is acidic
Among the given compounds, $N_3H$ (hydrazoic acid) is the acidic one. It is a weak acid but more acidic than the other nitrogen hydrides listed. $NH_3$ (ammonia) is basic, $N_2H_4$ (hydrazine) and $N_2H_2$ (diimide) are not acidic.
Laughing gas is prepared by heating
Laughing gas, or nitrous oxide ($N_2O$), is prepared by heating ammonium nitrate ($NH_4NO_3$). The reaction is: $$ NH_4NO_3 ightarrow N_2O + 2H_2O $$
$ Cl_2 reacts with CS_2 in presence of I_2 $ to form
$ CS_2 + 3Cl_2 \rightarrow CCl_4 + S_2Cl_2 $
Which of the following statements is/are correct for “when alkali metals are dissolved in liquid ammonia. We get...â€
Assertion : The lithium ion itself, and also its compounds, are more heavily hydrated
than those of the rest of the group members.
Reason : The is smallest among alkali metals and polarizes water molecules more easily than the other alkali metal ions.
Assertion and reason are correct statements and reason is the correct explanation of assertion.
