Answer: Option (e) is the correct answer.
Explanation:
An equilibrium reaction is defined as the reaction where rate of forward reaction will be equal to the rate of backward reaction.
For example,
So, here amount of reactants that is, nitrogen gas and hydrogen gas will be constant along with constant amount of formation of product that is, ammonia here.
In an equilibrium reaction there is presence of both reactants and products and hence, both reactants and products constitute the system.
Thus, we can conclude that all the given statements are true.
Answer:
138g
Explanation:
According to this question, sodium reacts with chlorine to form sodium chloride as follows:
Na(s) + Cl(g) → NaCl (aq)
According to the law of conservation of mass, matter can neither be created nor destroyed, but can only be transferred from one form to another. This means that the mass of the reactants in a chemical reaction must equate the mass of products of that reaction.
Hence, If 76g of sodium reacts with chlorine to produce 214g of sodium chloride, this means that to obey the law of conservation of mass, the mass in grams of chlorine that reacted is 214g - 76g = 138g
In this sense, the combined 76g of sodium and 138g of chlorine (reactants) will equate the 214g of sodium chloride (products) in obeisance to law of conservation of matter.
