Answer : The correct option is, (D) it is oxidized.
Explanation :
On the basis of electrons, there are two types of reactions :
(1) Oxidation reaction (2) Reduction reaction
Oxidation reaction : When an element loses electrons in a chemical reaction then that element gets oxidized in the chemical reaction and its oxidation number increases.
Reduction reaction : When an element gains electrons in a chemical reaction then that element gets reduced in the chemical reaction and its oxidation number decreases.
Hence, the correct answer is (D).
Answer:
2) All four statements are part of Dalton's original atomic theory.
Explanation:
The postulates of the Dalton’s atomic theory are:
- The matter is comprised of small units which are known as atoms.
- The atoms are indivisible which means that they can not be further divided.
- Atoms of the matter can neither be created nor be destroyed in the chemical reaction.
- All atoms of the particular element are identical.
- The atoms of the different elements vary in the size and the mass. and posses different properties.
- The compounds are formed by the different whole number combinations of the atoms.
<u>Hence, all 4 are correct.</u>
It’s the process of detecting a change of a objects position relative to its surroundings
Answer:
They attract or repel other charged objects without touching them.
Explanation:
My chemistry teacher always says like repels like opposite attracts.
