For the following, identify the most likely value for x.a. BHx b. CHx c. NHx d. CH2Clx
vekshin1

Given :

a. BH_x b. CH_x c. NH_x d. CH_2Cl_x .

To Find :

Find the most likely vale of x for each one .

Solution :

a . BH_x

Because boron have valency of 3 .

So , x = 3 .

b . CH_x

Valency of carbon is 4 .

x = 4 .

c . NH_x

Valency of nitrogen is 3 .

Therefore , x = 3 .

d . CH_2Cl_x

Now ,we know valency of carbon is 4 and hydrogen is 1 .

Also , two hydrogen are already there .

So , only 2 electrons left to share .

Since , chlorine have valency of 1 .

Therefore , only 2 electrons of chlorine can connect .

x = 2 .

Hence , this is the required solution .

How many molecules of CrCl₃ are produced when 2.89 moles of CuCl₂ react? *<br> 2Cr+3CuCI2-2CrCI3+3Cu
juin [17]

Explanation:

The reaction is CaCO

3

+2HCl→CaCl

2

+H

2

O+CO

2

.

Thus, 2 moles of HCl reacts with one mole of calcium carbonate to produce one mole each of calcium chloride, water and carbon dioxide respectively.

Hence, 3 moles of HCl will react with excess of calcium carbonate to produce 3×
