<span>The
scientist thought that the atom was the smallest particle in the universe is
John Dalton. He established the atomic theory which
consists of five; elements are made of extremely small particles called atoms,
atoms of different element have different sizes, mass and physic – chemical
properties, atoms cannot be divided further, destroyed or created, atoms can
combine to form compounds and in chemical reaction, atoms can be combined,
separated or rearranged</span>
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: 878 kJ of energy is there in cheeseburger
Explanation:
Given : calorific value of fat = 38kJ/g
calorific value of carbohydrate = 17 kJ/g
calorific value of protein = 17kJ/g
1 g of fat contains energy = 38 kJ
7.0 g of fat contains energy = 
1 g of carbohydrate contains energy = 17 kJ
25 g of fat contains energy = 
1 g of protein contains energy = 17 kJ
11 g of protein contains energy = 
Total energy = (266+425+187) kJ = 878 kJ
