Answer:
negative charge
Explanation:
Neutrons have no charge, protons have positive charge, and electrons have a negative charge
Answer:
the waves have a trough
Explanation:
just took the test on edg.
Answer : The correct option is, (C) 1.1
Solution : Given,
Initial moles of
= 1.0 mole
Initial volume of solution = 1.0 L
First we have to calculate the concentration
.


The given equilibrium reaction is,

Initially c 0
At equilibrium

The expression of
will be,
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)

where,
= degree of dissociation = 40 % = 0.4
Now put all the given values in the above expression, we get:



Therefore, the value of equilibrium constant for this reaction is, 1.1

and if you were wondering, the earth pushes back
The answer is number 1 - energy is emitted
Energy is released when an atom in an excited state returns to the ground state.
