Qué volumen ocupan 5 moles de un gas que se encuentran a 28°C y 3 atm de presión?
1 answer:
<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
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 :

Answer : The correct options are, and
Explanation :
Single displacement reaction : It is a type of chemical reaction in which the more reactive element displaces the less reactive element.
Option A reaction :
It is an example of double displacement reaction because in this reaction a positive cation and a negative anion of the two reactants exchange their places to form two new products.
Option B reaction :
It is an example of single displacement reaction.
Option C reaction :
It is an example of combination reaction because in this reaction two reactants react to give a single product.
Option D reaction :
It is an example of decomposition reaction because in this reaction a single reactant decomposes into two or more products.
Option E reaction :
It is an example of single displacement reaction because in this reaction the most react element, aluminium displaces the less reactive element, hydrogen.
Hence, the options B and E are single displacement reactions.
