Answer:
The set of coefficients that would correctly balanced the equation
NaCl → Na + Cl2 is the option D
(2,2,1)
Explanation:
In this reaction sodium chloride splits into sodium and chlorine.
For balancing the equation we should have number of atom of the element in the left hand side equal to the number of atom of the same element in the right-hand side.
so here in left hand side only one sodium and one chlorine is given and in the right-hand side one sodium and two chlorine is given.
So for the balancing the equation both the side should be same.
So we will write the balanced equation as
2NaCl → 2Na + Cl2
So, right now it is balanced that is two sodium and two chlorine on the left hand side as well as the right hand side.
Hence the coefficients are
2, 2, 1
Answer:
Explanation:
Given that
At starting separated = 1.20m
And the increase in background noise by Δβ = 5 dB, due to which the level of sound also rises
Based on the above information, the separation rf that is needed is shown below:
As we know that
Hence, the separation r_f i.e. required is
We simply applied the above equation so that the correct separation could come
