Answer:
Q = 7.0
Q = kc. The reaction is in equilibrium
Explanation:
Based on the reaction:
Br₂ + Cl₂ ⇄ 2BrCl
Equilibrium constant of the reaction, kc, is the ratio of <em>equilibrium concentrations</em> products over reactants powered to its reaction coefficient:
Kc = [BrCl]² / [Br₂] [Cl₂] = 7.0
Now, reaction quotient, Q, is write as the same Kc but the concentrations are actual concentrations:
Q = [BrCl]² / [Br₂] [Cl₂]
Replacing:
Q = [0.00415M]² / [0.00366M] [0.000672M]
Q = 7.0
Now, as Q = Kc = 7.0, the reaction mixture is in equilibrium

Answer:
D
Explanation:
The statement in the question above gives the statement of the law of conservation of matter. The law of conservation of matter states that matter can neither be created nor destroyed but can be converted from one form to another.
This particular law is talking about the indestructible nature of matter. Whatever form of matter we have presently was as a result of the fact that it was converted to from one initial form. It is this fundamental law that guides the operation of a wide number of scientific operations. Things like reaction between substances to form entirely or partially new substances are guided by these fundamental laws of nature
Answer:
This new temperature is 97.7 mL
Explanation:
Step 1: Data given
Volume = 0.225 L
STP = 1 atm and 273 K
Pressure = 2.7 atm
Temperature = 320 K
Step 2: Calculate new volume
(P1*V1)/T1 = (P2*V2)/T2
⇒with P1 = the pressure at STP = 1 atm
⇒with V1 = the volume = 0.225 L
⇒with T1 = the temperature at STP = 273 K
⇒with P2 = the new pressure = 2.7 atm
⇒with V2 = the new volume = TO BE DETERMINED
⇒with T2 = the new temperature = 320 K
(1atm *0.225 L)/273 K = (2.7 atm * V2) /320 K
8.24 * 10^-4 = 2.7 * V2 / 320K
2.7V2 = 0.264
V2 = 0.0977 L = 97.7 mL
This new temperature is 97.7 mL
