Answer:
The reaction shifts to the left.
Explanation:
Equilibrium constant (K) = 46.3
Reaction Quotient (Q) = 525
The relationship between Q and K with their implications are given as;
K = Q (No net reaction)
K > Q (Reaction shifts to the right)
K < Q (Reaction shifts to the left)
Since in this question, Q (525) > K (46.3)
The reaction shifts to the left.
Answer:
Solid Osmium transition metal reacts with Oxygen gas to produce solid Osmium tetroxide.
Os(s) + 2O₂(g) -> OsO₄(s)
Explanation:
Osmium tetroxide is another way of writing Osmium (VIII) oxide.
Leaving powdered osmium exposed to air in a room will slowly create osmium tetroxide at room temperature.
Similarly, osmium tetroxide vapor will readily be released from a liquid solution at room temperature.
Answer:
When we cook food in the kitchen, that's the region of higher concentration of the smell. By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, can smell it.
Answer:
Mole fraction of Nacl is 0.173
Explanation:
we know that
![P_{sol}=\chi_{solvent}P^0_{solvent}](https://tex.z-dn.net/?f=P_%7Bsol%7D%3D%5Cchi_%7Bsolvent%7DP%5E0_%7Bsolvent%7D)
where,
P
sol - the vapor pressure of the solution
χ solvent - the mole fraction of the solvent
P
∘
solvent - the vapor pressure of the pure solvent
This means that in order to be able to calculate the mole fraction of sodium chloride, you need to know what the vapor pressure of pure water is at
25
°
C You can use an online calculator to find that the vapor pressure of pure water at 25 C is equal to about 23.8 torr
.
![\chi_{water}= \frac{P{sol}}{P^0{water}}](https://tex.z-dn.net/?f=%5Cchi_%7Bwater%7D%3D%20%5Cfrac%7BP%7Bsol%7D%7D%7BP%5E0%7Bwater%7D%7D)
=0.827
Also we know that
![\chi_{water}+\chi_{Nacl}= 1](https://tex.z-dn.net/?f=%5Cchi_%7Bwater%7D%2B%5Cchi_%7BNacl%7D%3D%201)
This means that the mole fraction of sodium chloride is
χ_{Nacl}= 1-Χ_{water}
= 1-0.827 =0.173
Explanation:
During the formation of BeCl2, the beryllium atom bonds with two chlorine atoms via single covalent bonds. The number of electron pairs around the central atom will be two. No lone pair is found in the molecule. If we analyse this information then we can conclude that BeCl2 has sp hybridization.
