(a)
Interpretation:
The hydride
Concept Introduction:
Saline hydrides:
The elements present in group 1 and 2 form ionic compounds with hydrogen in which, the hydrogen is present as hydride ion
Molecular hydrides: Nonmetals form covalent molecular hydride that comprises of discrete molecules. These compounds are volatile and are bronsted acids. These are mostly formed by elements of p-blocks.
Metallic hydrides: Metallic hydrides are black, powdery, electrically conducting solids formed by heating certain elements of the d-block metals in hydrogen. Metallic hydrides releases hydrogen gas when they are treated or heated with an acid.

What inspired N. Bartlett to prepare this compound? (c) Fluorine is a stronger oxidising agent than chlorine. Why? (d)Write one use of chlorine gas.arrow_forwardConsider the following three statements about the reactivityof an alkali metal M with oxygen gas:(i) Based on their positions in the periodic table, the expectedproduct is the ionic oxide M2O.(ii) Some of the alkali metals produce metal peroxides or metalsuperoxides when they react with oxygen.(iii) When dissolved in water, an alkali metal oxide produces abasic solution.Which of the statements (i), (ii), and (iii) is or are true?(a) Only one of the statements is true.(b) Statements (i) and (ii) are true.(c) Statements (i) and (iii) are true.(d) Statements (ii) and (iii) are true.(e) All three statements are true.arrow_forward(A) if both sentences are true, (B) if both sentences are false, (C) if the first sentence is true but the second is false, and (D) if the first sentence is false but the second is true. 1. When a non-metallic oxide reacts with water, a base will be formed as the product of the reaction. When a metallic oxide like phosphorous pentoxide reacts with water, a base will be formed as the product of the reaction. 2. When water is mixed with oxides, hydrogen gas is evolved. A red to blue color change in the litmus paper indicates that the solution tested is an acid. 3. The filtrate in any filtration process is left on the surface of the filter paper, while the residue is collected at the bottom of the flask/container after passing through the filter paper. In the distillation process, the methyl violet served as a compound to acidify the water. 4. In the Winkler Titration Method, the starch solution turns colorless in the presence of free iodine in the solution to be titrated. In the Winkler…arrow_forward
