Answer:
A.
4Fe + 3O2 2Fe2O3 .........................
Answer:
opposite
Explanation:
Newton's 3rd law of motion: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
so it should be opposite because the ground/floor pushes the shoe up and forward, the shoe pushes down and back.

The value of the Kp is obtained from Kp = p.C2H6/p.C2H2 * pH2^2 as 1.
<h3>What is Kp?</h3>
The Kp is the equilibrium constant for a gas phase reaction we have to put down the equation for the Kp here as; Kp = p.C2H6/p.C2H2 * pH2^2.
We are told here that all the pressures are equal to 1 atm hence we substitute values; Kp = 1/1 ( (1)^2 =1
