Answer:
1.13 x 10²⁴formula units
Explanation:
Given parameters:
Number of moles of NH₄Cl = 1.87mol
Unknown:
Number of formula units = ?
Solution:
From mole concept;
1 mole of a substance contains 6.02 x 10²³ formula units
Now;
1.87 moles of NH₄Cl 1.87 x 6.02 x 10²³ = 1.13 x 10²⁴formula units
Answer:
the activation energy would be 200 kJ since we are looking an endothermic reaction.
Explanation:
First, to convert from C to K, add (C+273)=k
So -25+273=248
Answer:
4 monochlorination products can be formed.
Explanation:
Constitutional isomers : These are those compounds with same molecular formula but different atomic arrangement.For example: butane and 2-methly-propane.
On monochlorination of 2 methyl-butane we will have four possibilities of product which will be constitutional isomers of each other:
- 1-chloro-3-methyl butane :

- 2-chloro-3-methyl butane :

- 2-chloro-2-methyl butane

- 1-chloro-2-methyl butane
