Question

HCL contains 97.26% chlorine, phosphine
contains 91.1% phosphorous Applying the Law of
chemical combination, calculate how much
quantity of phosphorus will combine with
10.65g of chlorine to form a compound?

Answer 1

Answer:

the answer is Sulphuric acid

Explanation:

Answer 2

Answer:

3.072g

Explanation:

In HCI, chlorine = 97.26 parts and hydrogen 2.74 parts So, 2.74 parts of hydrogen combine with chlorine = 97.26 parts  

1 part of hydrogen combines with chlorine =  

7.26

97.26

​  

 parts = 35.5 parts  

In phosphine, phosphorus = 91.1 parts and hydrogen = 8.9 parts  

So, 8.9 pads of hydrogen combine with phosphorus = 91.1 parts .  

1 part of hydrogen combines with phosphorus =  

8.9

91.1

​  

=10.24 parts  

According to law of reciprocal proportions, when phosphorus and chlorine will react, they should combine in the ratio of 10.24: 35.5 by mass.  

So, 35.5 g of chlorine combine with phosphorus = 10.24 g  

10.65 g of chlorine will combine with phosphorus =  

35.5

10.24

​  

×10.65g=3.072g
