Answer:
Explanation:
meters has to go on the bottom of the bracket used for conversion
50m [ 1000 mm / 1 m]= 50000 mm The meters cancel
The equilibrium reaction is
N2O4(g)<----> 2NO2(g)
For reaction
Kp = (pNO2)^2 / pN2O4
Given:
Kp = 0.316
pN2O4 = 3.48 atm
To calculate
pNO2 = ?
0.316 = (pNO2)^2 / 3.48
(pNO2)^2 = 1.0997
pNO2 = 1.049 atm
Answer:
Explanation:
Arrhenius theory:-
The Arrhenius theory was introduced introduced by Swedish scientist named Svante Arrhenius in 1887.
According to the theory, acids are the substances which dissociate in the aqueous medium to produce electrically charged atoms ( may be molecule). Out of these species furnished, one must be a proton or the hydrogen ion, 
.
So,
The expression for acid, 
is:-
