Answer:
96.4567
Explanation:
245 cm in inches: two hundred and forty-five cm are equal to 245/2.54 = 96.45669 inches.
Answer:
Number of moles = No of mokecules/ Avigadro's number
Avigadro's number = 6.022*10(23)
No of moles = 1.505*10(24)/6.022*10(23)
No of moles =2.49 = 2.5mol
The number of mole is 2.5mol
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:
A) H2O > HCCH > NH3 > CH3CH3
Explanation:
H2O is known as a neural compound which a pH close to 7.0. This however makes it more acidic due to it having the lowest pH when compared to the others in the option.
The other options however have their acidic strength as follows: HCCH > NH3 > CH3CH3. This explains why the pattern of decreasing acidic strength is H2O > HCCH > NH3 > CH3CH3
