Concept explainers
(a)
Interpretation: To write a balanced chemical equation of carbon, silicon, germanium and tin with elemental chlorine.
Concept introduction:
The elements carbon, silicon, germanium and tin belongs to group
(b)
Interpretation: In the following compounds;
Concept introduction: An ionic bond is formed between metal and non-metal. The non-metals are electronegative in nature and metals are electropositive in nature. Therefore, non-metals get electrons very easily from metals and form ionic bond.
A covalent bond is formed between two non-metals that have approximately similar electronegativities. The non-metals can share electrons with each other to form a covalent bond.
(c)
Interpretation: To write the reactions of
Concept introduction: Hydrolysis is a chemical process involving breaking a bond in a molecule using water. There are three types of hydrolysis; salt hydrolysis, acidic hydrolysis and basic hydrolysis.

Chemistry & Chemical Reactivity
- Would the reaction of magnesium, mg with oxygen be more or less vigorous than Al?arrow_forwardCompounds such as NaBH4, Al(BH4)3, and LiAlH4 are complex hydrides used as reducing agents in many syntheses. (a) Give the oxidation state of each element in these compounds. (b) Write a Lewis structure for the polyatomic anion in NaBH4, and predict its shape.arrow_forwardMagnesium carbonate is soluble in water (100 mg / L) whereas strontium carbonate is only slightly soluble in water (11 mg / L). Would you expect barium carbonate to be more or less soluble than calcium carbonate? Why? Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A−, B−, and C−ions, all of which are colorless. When a solution of C is mixed with one containing B− ions, the color changes from red to yellow. Which species is oxidized? Which species is reduced? When a solution of C is mixed with one containing A− ions, the color remains red. Is C a better oxidizing agent than A? Or it is a better oxidizing agent than B? Arrange A, B, and C in order of increasing strength as an oxidizing agent.arrow_forward
