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:
Ba
Explanation:
Magnesium is the element of second group and third period. The electronic configuration of magnesium is - 2, 8, 2 or
There are 2 valence electrons of magnesium.
Fluorine is the element of seventeenth group and second period. The electronic configuration of fluorine is - 2, 7 or
There is 1 valence electron of fluorine.
They will combine and form
<u>The same type of compound is formed by the other members of the group 2 since they will have 2 valence electron.</u>
Group 2 includes:- beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
Hence, correct options is:- Ba
