CH4 is <u>not</u> soluble in water

whereas CH3OH <u>is</u> soluble in water.

Olin [163]3 years ago

Answer:

CH4 is non polar covalent compound and non polar covalent compounds are insoluble in polar covalent compounds like water.

And CH3OH is soluble in water because it polar and also due to hydrogen bonding.

If ch4 and c4h8 are released simultaneously at ends of a 50.0cm long glass tube, at what distance from the left end of the tube
Keith_Richards [23]

Answer:

They meet at the distance of 32.5 cm

Explanation:

The rate of diffusion is inversely proportional to the molar mass of gases.

If diffusion is represented as d and mass of gases as M. Then , rate is given as:

d=k\sqrt{\frac{1}{M}}

For , two gases

\frac{d_{1}}{d_{2}}=\sqrt{\frac{M_{2}}{M_{1}}}

First , Calculate the ,molar mass of each gas :

CH4 = 1 (mass of C) + 4(mass of H)

= 1(12)+4(1)

= 12 + 4 = 16 gram

M1 = 16 gram

C4H8 = 4(mass of C) + 8(Mass of H)

= 4(12) + 8(1)

= 48 + 8

M2 = 56 grams

d1 is diffusion of CH4

d2 = diffusion of C4H8

\frac{d_{1}}{d_{2}}=\sqrt{\frac{M_{2}}{M_{1}}}

\frac{d_{1}}{d_{2}}=\sqrt{\frac{56}{16}}

\frac{d_{1}}{d_{2}} = 1.87

This means CH4 diffuse 1.87 times faster than C4H8

Now, the mathematical part

If velocity of C4H8 = 1 cm/sec , then velocity of CH4 = 1.87 cm/sec

v1 = 1.87 cm/sec

v2 = 1 cm/sec

Let both meet at time "t". If distance travelled by CH4(s1) = x , then remaining(s2) distance (50-x) is travelled by C4H8

(see the attached image)

time =\frac{distance}{speed}

since both meet at same time so t = constant.

\frac{s1}{v1}=\frac{s2}{v2}

\frac{x}{1.87}\frac{50-x}{1.00}

on solving for x we get,

x = 17.42 cm

from the other side the distance is (50 - x)

= 50 - 17.42 = 32.5 cm
