The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant is a figure that tells us the extent to which the reactants have been converted to products in a reaction.
Now we have the reaction; PCl3(g) + Cl2(g) ⇄ PCl5(g) hence we can write;
Q = [PCl5]/[PCl3] [Cl2]
Q = 0.39/0.21 * 0.41
Q = 4.5
The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.

Answer:
The answer is 30 g of sodium hydrocarbonate
Explanation:
This is a acid-base reaction, so in order to neutralise the spilled acid, the mol of spilled acid should be calculated.
M = n / V => n = M x V = 0.028 x 6.2 = 0.1736 mol
Since 1 mol of sulfuric acid generates 2 mol of H⁺, so the mole of H⁺ is 0.3472 mol or 0.35 mol with two significant figures.
To neutralized the acid, we need at least the same mole of base, so we need at least 0.35 mol of NaHCO₃, which can be converted to its mass at 29.4 g.
Since the answer need to be expressed in two significant figures and also need to make sure to neutralize all the acid, so we will use a little excess base. The answer is 30 g.

No
Explanation:
A laser generates a beam of very intense light. The major difference between laser light and light generated by white light sources (such as a light bulb) is that laser light is monochromatic, directional and coherent. Monochromatic means that all of the light produced by the laser is of a single wavelength.
Answer: a.KOH
Potassium hydroxide is an ionic compound where the K+ is the cation and OH−is the anion. At the same time, the compound also contains a covalent bond since the anion, OH−is formed from electron sharing between the O and H atoms.
