when chlorine is added to acetylene tetrachloroethane is formed How many grams of tetrachloroethane are ade if 15 liters of chlo
1 answer:
35.5 g of tetrachloroethane is added if 15 grams of chlorine is used with excess .
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
Balanced chemical equation:
→
In your case, 2 moles of chlorine gas are needed to produce 1 mole of tetrachloroethane, which implies that there's a 2:1 mole ratio between the two.

Answer:
El volumen del gas en el recipiente es 3.29 L si se disminuye la temperatura a 7°C
Explanation:
La Ley de Charles es una ley de los gases que relaciona el volumen y la temperatura de una cierta cantidad de gas a presión constante.
Esta ley establece que el volumen es directamente proporcional a la temperatura del gas. Es decir que si la temperatura aumenta, el volumen del gas aumenta, mientras que si la temperatura del gas disminuye, el volumen disminuye.
Matemáticamente, si la cantidad de gas y la presión permanecen constantes, el cociente entre el volumen y la temperatura siempre tiene el mismo valor:
Suponiendo un cierto volumen de gas V1 que se encuentra a una temperatura T1 al comienzo del experimento, al variar el volumen de gas hasta un nuevo valor V2, entonces la temperatura cambiará a T2, y se cumplirá:
En este caso, sabes:
- V1= 3.5 L
- T1= 25 °C=298 °K (siendo 0°C=273°K)
- V2=?
- T2=7 °C=280 °K
Reemplazando:
Y resolviendo obtienes:
V2= 3.29 L

Answer:
Explanation:
The Ideal Gas equation is:
(1)
Where:
is the pressure of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin.
is the volume
It is important to note that the behavior of a real gas is far from that of an ideal gas, taking into account that <u>an ideal gas is a single hypothetical gas</u>. However, under specific conditions of standard temperature and pressure (T=0\°C=273.15 K and P=1 atm=101,3 kPa) one mole of real gas (especially in noble gases such as Argon) will behave like an ideal gas and the constant R will be .
However, in this case we are not working with standard temperature and pressure, therefore, even if we are working with Argon, the value of R will be far from the constant of the ideal gases.
Having this clarified, let's isolate from (1):
(2)
Where:
is the absolute temperature of the gas in Kelvin.
(3)
Finally:
