Qué volumen ocupan 5 moles de un gas que se encuentran a 28°C y 3 atm de presión?
lys-0071 [83]

<em>What volume do 5 moles of a gas occupy at 28 ° C and 3 atm of pressure?</em>

<em />

<h3>Further explanation</h3>

In general, the gas equation can be written  

\large {\boxed {\bold {PV = nRT}}}

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

n= 5 moles

T=28 +273=301 K

P=3 atm

The volume of the gas :

\tt V=\dfrac{nRT}{P}\\\\V=\dfrac{5\times 0.082\times 301}{3}\\\\V=\boxed{\bold{41.136~L}}

Of ozone, molecular oxygen, and oxygen radicals, which is the most stable form of oxygen? How do you know?
PtichkaEL [24]

Oxygen has a strong double bond which has more stability than the single co-ordinate bond in ozone, therefore more energy is required to break the O2 bonding than ozone, so the ozone molecule is more reactive than oxygen gas. ... The oxygen free radical contains two unpaired electrons in its valence shell.

The formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1. as shown below:

  • N_2 + 3H_2 \rightarrow 2NH_3
<h3>What is the equation of the formation of ammonia?</h3>

Ammonia gas is formed from the reaction between nitrogen gas and hydrogen gas.

Three moles of hydrogen gas will react with 1 mole of nitrogen gas to form 2 moles of ammonia gas.

The equation of the reaction is given below as:

N_2 + 3H_2 \rightarrow 2NH_3

Therefore, the formation of ammonia gas involves reacting hydrogen gas and nitrogen gas in a mole ratio of 3 to 1.
