- (a) Describe the lanthanide contraction using basic atomic structure theory (b) What are its effects on the properties of lanthanidesarrow_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(a) One of the alkali metals reacts with oxygen to form a solidwhite substance. When this substance is dissolved in water,the solution gives a positive test for hydrogen peroxide, H2O2.When the solution is tested in a burner flame, a lilac-purpleflame is produced.
