What is the balanced equation for the reaction of lithium metal with fluorine gas? Li ( s ) + F ( g ) → LiF ( s ) Li ( s ) + F 2

( g ) → LiF ( s ) 2 Li ( s ) + F 2 ( g ) → 2 LiF ( s ) Li ( s ) + F 2 ( g ) → LiF

What happens to the molecules of water when the water changes from liquid to gas?.

ICE Princess25 [194]

Answer: Molecules only speed up when given energy, such as heating. When you heat water enough, it will boil and turn into water vapor. So, therefore, if water's molecules speed up, it will go into the gas phase

Explanation: As that liquid water is further heated, it evaporates and becomes a gas—water vapor. These changes between states (melting, freezing, and evaporating) happen because as the temperature either increases or decreases, the molecules in a substance begin to speed up or slow down.

A given volume of methane diffuses in 20 seconds. How long will it take the same volume of hydrogen to diffuse under the same co

Airida [17]

The time taken for the same volume of methane gas to diffuse is 7.1 s.

<h3>Rate of gas diffusion</h3>

The rate at which a given mass of diffuses is inversely proportional to the molar mass of the gas.

$\frac{t_2}{t_1} = \sqrt{\frac{M_2}{M_1} }$

where;

M1 is the molar mass of methane (CH4) = 16 g
M2 is the molar mass of hydrogen as = 2
t1 is time taken for methane = 20 s
t2 is the time taken for hydrogen = ?

$\frac{t_2}{t_1} = \sqrt{\frac{M_2}{M_1} }\\\\\frac{t_2}{20} = \sqrt{\frac{2}{16} }\\\\\frac{t_2}{20} = \frac{\sqrt{2} }{4} \\\\t_2 = \frac{20\sqrt{2} }{4} \\\\t_2 = 5\sqrt{2} \\\\t_2 = 7.1 \ s$

Thus, the time taken for the same volume of methane gas to diffuse is 7.1 s.
