Answer: The corresponding value of 
for this reaction at 84.5°C is 0.00232
Explanation:
Relation of with is given by the formula:
where,
= equilibrium constant in terms of partial pressure = ?
= equilibrium constant in terms of concentration = 0.0680
R = Gas constant = 
T = temperature =
= change in number of moles of gas particles = 
Putting values in above equation, we get:
Thus the corresponding value of for this reaction at 84.5°C is 0.00232
Answer:
yes that is true.Because they are ions.oppositely chared ions attract each other
Answer:
Explanation:
Hello!
In this case, since the molar mass of a chemical compound is computed by averaging the atomic mass of each element in the molecule and the amount of atoms; which in this case there are 9 carbon atoms, 13 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms; thus, we compute the average as shown below:
Now, we plug in the atomic masses to obtain:
Best regards!
Answer:
Sound waves travelling through the air: Sound waves travelling through air are just like longitudinal waves lacking compressions and rarefactions. The speed of sound waves in air is approximately 332 metres per second.
Light waves travelling through air: Light waves travel in air at a much faster rate than sound waves. Light waves can travel with a speed of 300 000 kilometres per second through air.
Sound waves traveling through metal: Sound waves travel about 17 times faster in metal as compared to air. The sound waves travel with an approximate speed of 5,960 meters per second in metals.
Light waves travelling through metal: The speed of light waves in a metal medium is usually at a net speed which is less than 3.00 x 108 m/s.
Light travels faster than sound waves because light waves are not pressure waves like the sound waves. They also do not require a medium as the sound waves.
Answer:
Explanation:
428 x 10³ Pa = 4.28 x 10⁵ Pa = 4.28 atm
We shall use the gas equation
P₁V₁ / T₁ = P₂V₂ / T₂
7.66 x 10 / ( 273 + 27 ) = 4.28 x 30 / T₂
.255 = 128.4 / T₂
T₂ = 503.53
= 503.53 - 273 = 230.53⁰C .
