Answer:
Lithium is used in making electrochemical cells.
Answer:
Don't worry school's will re-open in August 2021. ._.
Explanation:
Work Done = force x displacement. So in this case the 15N is the force (because weight is a force) and 0.60m is the displacement. Therefore 15 x 0.6 = 9 Joules of work done (btw, work done can also be referred to as energy transferred)
Answer is both (b) and (d).
<em>Explanation;</em>
Equilibrium constant is written as a ratio between concentrations of products and reactants.
The equilibrium reaction is
A(g) ⇄ B(g)
Hence, the equilibrium constant can be expressed as
K = [B(g)] / [A(g)]
If there is more B, then A should be less. Hence, K value would be more than 1.
Hence, according to the given choices, K = 4000 and K = 1 x 10⁶ can be taken as correct answers.
