Answer: Some atoms of the same elements that have different atomic masses are called isotopes
Explanation:
so the atoms are the same element but different in mass. Since the isotopes have the same number of protons and electrons the isotopes have much the same chemical behavior. Since the isotopes have different numbers of neutrons the nuclear behavior differs.

Answer:
Option-D is the correct answer.
Explanation:
Hydrocarbons are classified as;
a) Saturated Hydrocarbons:
Those hydrocarbons in which all carbon atoms are bonded to each other through a single covalent bonds are known as Saturated Hydrocarbons.
Example:
Alkanes with a general formula CnH₂n+₂ belongs to saturated hydrocarbons. The Hydrogen Deficiency Index of Alkanes is zero, means it does not contain any double or triple bond.
i) H₃C-CH₃ Ethane
ii) H₃C-CH₂-CH₃ Propane
iii) H₃C-CH₂-CH₂-CH₃ Butane
b) Unsaturated Hydrocarbons:
Those hydrocarbons in which a double bond (Alkenes) or triple bond (Alkynes) is formed between two carbon atoms are called as unsaturated Hydrocarbons.
Example:
Alkene with a general formula CnH₂n belongs to unsaturated hydrocarbons. The minimum Hydrogen Deficiency Index of Alkenes is one, means it contain minimum one double bond.
i) H₂C=CH₂ Ethene
ii) H₂C=CH-CH₃ Propene
iii) H₃C-CH=CH-CH₃ 2-Butene
Alkyne with a general formula CnH₂n-₂ belongs to unsaturated hydrocarbons. The minimum Hydrogen Deficiency Index of Alkynes is two, means it contain minimum one triple bond.
i) HC≡CH Ethyne
ii) HC≡C-CH₃ Propyne
iii) H₃C-C≡C-CH₃ 2-Butyne
After one half life initial amounts gets half so :-
- First half life :- 350÷2 = 175 grams
- second half life :- 175 ÷2 = 87.5 grams
- third half life :- 87.5 ÷2 = 43.75 grams
so at last of third half life amount left = 43.75 grams
each time amount get half

<u>Answer:</u>
<em>The molarity of the solution is </em>
<em></em>
<u>Explanation:</u>
The Balanced chemical equation is
Mole ratio of : KCl is 1 : 1
So moles = moles KCl
So Molarity
= 0.000402M or mol/L is the Answer
(Or) is the Answer
