Answer:

When silver nitrate (AgNO3) and potassium chloride (KCl) combine in their liquid state, they form two products by double displacement method.

Silver Chloride (AgCl) and Potassium Nitrate (KNO3)

The reaction is AgNO3 + KCl --- AgCl + KNO3

The precipitate formed is AgCl

A gas diffuses 1/6 times faster than hydrogen gas (H2). What is the molar mass of the gas? 59.95 g/mol 66.54 g/mol 68.68 g/mol 7
taurus [48]

Solution us here,

let the rate of diffusion of H2(r1) be x and⁷ the rate of diffusion of gas(r2) be x+x/6=7x/6.

Molar mass of H2 (M1)=2 g

Molar mass of gas(M2)= ?

Now, from the Ghram's law of diffusion of gas,

\frac{r1}{r2}  =   \sqrt{ \frac{m2}{m1}  }   \\ or \:  \frac{x}{ \frac{7x}{6} }  =  \sqrt{ \frac{m2}{2} }  \\ or \:  \frac{6}{7}  =  \sqrt{ \frac{m2}{2} }  \\ squaring \: in \: both \: sides \\  \frac{36}{49}  = \frac{m2}{2}  \\ or m2 = 1 .469

here, it looks like I have done wrong.

But all of the answers in option are wrong.

Because, rate of diffusion of any gas is inversely proportional to the square root of its malor mass.

And in the question, gas has higher rate of diffusion than hrdrogen. So it should have molar mass less than hydrogen.
