(i) NaH + H 2 O undersetΔ longrightarrow NaOH + H 2 <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/8053e2568e7295c0a3e63fa3beac2fe2-.png" /> (i), (ii) both statements are correct. (iii) Nickle cannot form saline hydride Thus, statement is incorrect.

Q. Which of the following statements are collect?
(i) NaH(s) reacts violently with water to form $N a O H$ and $H_{2}$
(ii) An example for electron rich hydride is $N H_{3}$
(iii) Nickel forms saline hydride

(i), (ii)

(ii), (iii)

(i), (ii), (iii)

(i), (ii)

(i) $N a H + H_{2} O Δ ⟶ N a O H + H_{2}$

(i), (ii) both statements are correct.

(iii) Nickle cannot form saline hydride

Thus, statement is incorrect.
