K2O+H2O=KOH<br> What,if anything, should be done to balance this chemical equation?

VladimirAG [237]

As is, the equation has:

Reactants:
2 K
2 O
2 H

Products:
1 K
1 O
1 H

So, we can add coefficients to balance the equation:
K2O + H2O = 2KOH

The coefficient means that there are 2 moles of KOH, and now the equation is balanced as there is 2 of everything on both sides.

The following data are obtained for the decomposition of N2O5 at a certain temperature: 2N2O5(g) ↔ 4NO2(g) + O2(g) Time(s) 0 200

cricket20 [7]

Answer:

K = 0.0003 s⁻¹

Explanation:

The reaction is

2N₂O₅ = 4NO₂ + O₂

The equilibrium is

$K[N_{2} O_{5} ]=-\frac{1}{2} \frac{d[N_{2} O_{5} ]}{dt} \\\int\limits^y_x {d[N_{2} O_{5} ]}{} \, =-2k\int\limits^t_0 {dt} \,\\ln[N_{2} O_{5} ]=-2kt+ln[N_{2} O_{5} ]$

a plot is attached

From the plot, the slope is -0.0006

-2 * K = -0.0006

K = 0.0003 s⁻¹
