The element that was oxidized is carbon, as it’s oxidation state increased (electrons were lost) from +2 (in the reactants) to +4 (in the products). The element that was reduced is nitrogen, as it gained electrons and went from a +2 oxidation state (reactants) to a 0 oxidation state (products). Since the carbon was oxidized and it’s electrons were used to reduce the nitrogen, carbon is the reducing agent.
Particle Charge
Proton +1
Neutron. 0
Electron. -1
Chemical properties of elements are primarily determined by the electrons/protons but not by the neutrons. Therefore, the Isotopes of the same element have similar chemical behaviour.
Answer:
C is Correct
Explanation:
Protons and Neutrons make up the Nucleus while Electrons surround the nucleus in circular orbits with continuous rotation.
Explanation:
Carbon is a non-metal then carbon dioxide is a non-metal oxide. Non-metal oxides reacts with water to produce acids.
non-metal oxide + water ----> acid
carbon dioxide + water ----> carbonic acid
CO₂ + H₂O ---> H₂CO₃
Answer: H₂CO₃ (H2CO3)
Answer:
It is known generally that polar compounds are soluble in polar solvents. Based on the structure of benzoic acid, it comprises the non-polar C6H6 group and polar COOH group. Based on the structure, in benzoic acid, the nonpolar hydrocarbon outweighs and influences the polar part as nonpolar, due to which benzoic acid is not soluble in water.
On the other hand, benzoic acid produces sodium salt benzoic acid when it reacts with 2.5 M sodium hydroxide, this salt is ionic. Generally, the ionic compounds are soluble in water. Therefore, the salt of benzoic acid gets dissolved in water. Hence, benzoic acid is soluble in the solution of sodium hydroxide.
