Answer:
The new temperature of the gas is 200 Celsius degrees.
Explanation:
Charles's Law consists of the relationship between the volume and temperature of a certain amount of ideal gas, which is maintained at a constant pressure, by means of a proportionality constant that is applied directly.
In this way, Charles's law is a law that says that the quotient that exists between volume and temperature will always have the same value:
Assuming you have a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment, if you vary the volume of gas to a new value V2, then the temperature will change to T2, and it will hold:
In this case:
- V1= 20 L
- T1= 100 °C
- V2= 40 L
- T2= ?
Replacing:
Solving:
T2=200 °C
<u><em>The new temperature of the gas is 200 Celsius degrees.</em></u>
Mass of H₂ produced = 12 g
<h3>Further explanation</h3>
Given
32 grams of CH₄
Required
mass of H₂
Solution
Reaction
CH₄ + H₂O (+ heat) → CO + 3H₂
mol CH₄(MW= 16 g/mol) :
= mass : MW
= 32 g : 16 g/mol
= 2
From the equation, mol ratio CH₄ : H₂ = 1 : 3, so mol H₂ :
= 3/1 x mol CH₄
= 3/1 x 2
= 6
Mass H₂(MW = 2 g/mol) :
= mol x MW
= 6 x 2
= 12 g
We see in the given name of the hydrocarbon that the root word is pentane from 2,2,4-trimethylpentane. Pentane is a hydrocarbon chain that contains 5 carbon atoms. Therefore, the answer to this item is 5 carbons.
Chemical property is when it's observed during a reaction in which the chemical composition or identity of the substance is changed. physical properties is when properties that do change the chemical nature of matter.
example for this is smell, color, freezing point, etc.
Dilution law is given as:
(1)
where, = molarity of initial concentrated solution.
= volume of initial concentrated solution.
= molarity of final diluted solution.
tex]V_{2}[/tex] = volume of final diluted solution.
Volume of initial concentrated solution of = 100.0 mL
Molarity of initial concentrated solution of = 5.50 M
Volume of final diluted solution of = 0.950 M
Put the values in formula (1),
Hence, final diluted volume of the solution is .
