Answer:
16% v/v es la nueva concentración de alcohol en la solución
Explanation:
El porcentaje volumen/volumen (% v/v) es definido como 100 veces la relación entre el volumen de soluto (Alcohol en este caso) y el volumen total de la solución (Agua + Alcohol). Para resolver esta pregunta necesitamos hallar el volumen de alcohol y el de agua:
<em>Volumen alcohol:</em>
320cc * (20cc etanol / 100cc) = 64cc etanol
<em>Volumen agua:</em>
80cc + (320cc-64cc) = 336cc agua
<em>% v/v:</em>
64cc / (336cc + 64cc) * 100
= 16% v/v es la nueva concentración de alcohol en la solución
Answer: A reversible reaction is a reaction that takes place in back and front directions. If the reaction were to reach equilibrium, the rate of forward direction would be equal to that of the reverse reaction.
Explanation:
Reversible reactions :
These are the reaction in which reactants reacts to give product and products reacts to give reactants as a product in return.
- In above equation, 'A' and 'B' are reacting together to give 'C' and 'D', as products and vice-versa.
- When the above reaction reaches equilibrium the rate of forward and backward reaction becomes equal.
You can use physical methods to separate a mixture and also some chemical methods too.
Mixture is just a physical combine.
However a compound is a chemical combine so you must use special methods to separate it
What is the question and are there answers to go with it
I would say the answer is liquids
