Explanation:
As it is given that solubility of water in diethyl ether is 1.468 %. This means that in 100 ml saturated solution water present is 1.468 ml.
Hence, amount of diethyl ether present will be calculated as follows.
(100ml - 1.468 ml)
= 98.532 ml
So, it means that 98.532 ml of diethyl ether can dissolve 1.468 ml of water.
Hence, 23 ml of diethyl ether can dissolve the amount of water will be calculated as follows.
Amount of water = 
= 0.3427 ml
Now, when magnesium dissolves in water then the reaction will be as follows.

Molar mass of Mg = 24.305 g
Molar mass of
= 18 g
Therefore, amount of magnesium present in 0.3427 ml of water is calculated as follows.
Amount of Mg =
= 0.462 g
So to balance an equation, you need to get the same amount of each type of element on either side of the --> . So you pretty much are given the subscripts in the equations and you need to add coefficients (just normal numbers) in front of any formula that needs it, keeping anything balance.

turns into

These coefficient numbers are the molar ratios, so 2 moles of KCl3 for every 3 moles of O2 so 1. 3:2
Then you can use these ratios of find out how many moles of one thing are needed if you are given the amount of another.

and use cross multiplication to solve for whatever you don't know

To me it looks like gas.
Gas- CORRECT!
Solid- incorrect because if this were a depiction of a solid then the particles would be much much closer together.
Liquid - incorrect because the particles would be a little more crowded together.
Plasma- I do not think that this answer is correct because, even though the spacing of particles is similar to the spacing of particles in plasma, the particles in plasma are charged particles(nuclei (+) and electrons(-)). Therefore, because the diagram doesn't have the particles labeled with charges, I believe that Plasma cannot be the correct answer.
Any questions?
Answer:
2.13g
Explanation:
Atomic mass of CO2 = 12 + 32 = 44g/Mol
Atomic mass of C3H8 = 36 + 8 = 44g/Mol
Reaction
C3H8 + 5O2 --> 3CO2 + 4H2O
3CO2 = 6.39g
Required C3H8 = (6.39/(44 x 3)) x 44 = 2.13g
The system is not at equilibrium.
The reaction will proceed to the right to attain the equilibrium.
Let's consider the following reaction.
2 NOBr(g) ⇌ 2 NO(g) + Br₂(g)
The pressure equilibrium constant (Kp) is 60.6. To determine if the system is at equilibrium when the pressure of each component is 1.75 atm, we have to calculate the reaction quotient (Q) and compare it with Kp.
Q = [NO]².[Br₂] / [NOBr]²
Q = (1.75)².(1.75) / (1.75)²
Q = 1.75
Since Q ≠ Kp, the system is not at equilibrium.
Since Q < Kp, the reaction will proceed to the right to attain the equilibrium.
