Answer: 30 m/s
Explanation:
Use the first kinematic equation for linear motion
The answer is homogeneous
To be able to write correctly the equilibrium expression of a reaction, we need to know the balanced reaction and the phases of the substances in the reaction. When substances are solid, pure liquid they are not included in the expression. We do as follows:
<span>4KO2(s) + 2H2O(g) = 4KOH(s) + 3O2(g)
K = [O2]^3 / [H2O]^2</span>
4 grams , mass cannot be created or destroyed. it has to be the same on both sides of the equation
