There are three kinds of Hydrogen in 2-methyl-2-butene
The correct question is
How many kinds of hydrogen atoms are present in 2-methyl-2-butene
<h3>What is an atom ?</h3>
Atom was discovered by Dalton's Atomic theory , he predicted that each element consist of large number of a very small thing known as atom.
In the structure of 2-methyl-2-butene there are 3 types oh Hydrogen
1. Attached to the Carbon atom connecting the methyl ion to the butene
2. Connected to the last Carbon atom
3. Connected to the Carbon bond having double bond.
Therefore there are three kinds of Hydrogen in 2-methyl-2-butene.

Answer:</h3>
The mole fraction of carbon dioxide is 0.0559
<h3>
Explanation:</h3>
- Mole fraction of a gas in a mixture of gases its given by dividing the number of moles of the gas by the total number of moles of the mixture.
In this case, we are given a mixture of N₂, CO₂ and He
To find the mole fraction of CO₂, first we need to calculate the total number of moles in the mixture.
Individual number of moles for each gas are;
Moles = mass ÷ Molar mass
Therefore;
Nitrogen gas (N₂)
Mass =18.0 g
Molar mass = 28.02 g/mol
= 0.642 moles N₂
Helium gas (He)
Mass = 50.5 g
Molar mass = 4.0 g/mol
= 12.625 moles He
Carbon dioxide (CO₂)
Mass = 34.6 g
Molar mass = 44.01 g/mol
= 0.786 moles CO₂
Therefore;
The total number of moles in the mixture;
= 0.642 moles + 12.625 moles + 0.786 moles
= 14.053 moles
Thus;
The mole fraction of CO₂= Moles of CO₂ ÷ Total number of moles
= 0.786 moles ÷ 14.053 moles
= 0.0559
Hence the mole fraction of carbon dioxide is 0.0559
Answer:
Neutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons). These two alternate forms of carbon are isotopes.
