What is Oxidizing agent and give some examples?

Posted by Susri Namrata Deep 4 years, 2 months ago

CBSE > Class 10 > Science

2 answers

F D 4 years, 2 months ago

The substances which gets reduced is the oxidizing agent. Example- When zinc oxide is heated with carbon, then zinc metal and carbon monoxide are formed. ZnO + C Δ→ Zn + CO In this reaction, zinc oxide (ZnO) is losing oxygen, so it's being reduced to Zinc (Zn). On the other hand, carbon (C) is gaining oxygen, so it's being oxidized to carbon monoxide (CO). In this reaction, zinc oxide is the oxidizing agent whereas carbon is the reducing agent

A nucleon is one of the particles of the atomic nucleus. Each atomic nucleus includes one or more Nucleons. These are surrounded by one or more electrons. They occupy a small space within the nucleus. Every atom is made up of nucleons which are further divided into electrons, protons, and neutrons that orbit the nucleus. An atom is just like a mini solar system, with electrons orbiting a central star which is the nucleus, composed of nucleons.
