<u>Answer:</u> The value of 
for the equation is 
<u>Explanation:</u>
The given chemical reaction is:
The chemical equation for which the equilibrium constant is to be calculated follows:
As, the equation is the result of the reverse of given reaction. So, the equilibrium constant for the equation will be the inverse of equilibrium constant for the given reaction.
The value of equilibrium constant for the equation is:
We are given:
Putting values in above equation, we get:
Hence, the value of for the equation is
Answer:
C. Unbalanced
Explanation:
A force which can change the state of an object by changing it's speed, position or direction of motion is known as an unbalanced force. It is the resultant of all forces which are acting on a body and causing a change in the state of rest of motion of the body.
Assume a box is resting on the floor. The forces acting on the box in the rest are Normal (by the ground on the box) in upward direction and gravitational force Mg (due to gravity). Although these two forces are acting on the box, it is still in rest because these forces are balanced to each other. When we pull or push the box by applying appropriate force, the box will start to move because the force applied by us is unbalanced and there is no any force in the opposite direction to make this force balanced.
Answer:
Group B elements
Explanation:
Group B metals are referred to as transition metals. They are located in the middle of the periodic table between Group IIA and Group IIIA. They provide transition between the "base formers" on the left and "acid formers" on the right.
