Diamond consists of carbon atoms tetrahedrally arranged and bonded by strong covalent bonds. Graphite consists of carbon atoms arranged in hexagonal rings and in layers. Each carbon atom is bonded to three other atoms arranged hexagonally in layers.
Answer:
Gas is the state of mater which changing its shape and volume according to the volume and shape of container.
Explanation:
Gas is the state of mater which changing its shape and volume according to the volume and shape of container.
Properties of gas:
Molecule of gases randomly move everywhere and occupy all available space.
Gases don't have definite volume and shape and take the shape and volume of container in which it present.
Their densities are very low as compared to the liquid and solids.
Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.
The very weak inter molecular forces are present between gas molecules.
Explanation:
Oxidizing agent is the reactant in the chemical reaction which oxidizes others and reduces itself.
Reducing agent is the reactant in the chemical reaction which reduces others and oxidizes itself.
(a) In the given reaction :-
Cr exists in +6 oxidation state in and forms in which it has +3 oxidation state.
Thus, it is reduced in the chemical reaction. Thus, is oxidizing agent and is the reducing agent.
(b) In the given reaction :-
Zn exists in 0 oxidation state in and forms in which it has +2 oxidation state.
Thus, it is oxidized in the chemical reaction. Thus, Zn is reducing agent and is the oxidizing agent.
