Answer:
The answer to your question is : letter B. 0.25 atm
Explanation:
To solve this problem we need to use the combined gas law:
<u>P₁V₁</u> = <u>P₂V₂</u>
T₁ T₂
Data
P1 = 0.99 atm V1 = 2 l T1 = 273K
P2 = ? V2 = 4 l T2 = 137K
Now, the clear P2 from the equation and we get
P2 = P1V1T2 / T1V2
Substitution P2 = (2 x 0.99 x 137)/(273 x 4)
P2 = 271.26 / 1092
Result P2 = 0.248 atm ≈ 0.25 atm
The liquid part of a homogeneous mixture is most often than not the a. solvent
This depends on the type of homogeneous mixture at hand. For a liquid-solid homogeneous mixture, the liquid works as the solvent. For a gas-liquid homogeneous mixture, the liquid often works as the solvent as well. However, for a liquid-liquid homogeneous mixture, the liquid acts as both the solute and solvent.
Answer:
C is the correct answer 35% and 9%
Answer:
copper rally isn't useful like iron we have cars and all that but copper is made for like copper coins and wires
Explanation:
Iron is more reactive than copper as copper has less outer shells than iron so copper is less likely to react with another element as it has a stronger hold over the electrons.
1) No. of atoms of all elements participating in the reaction are to be balanced.
2) Pressure Change should be noted (because, if ∆P≈0, it shows the reaction is in equilibrium).
3) The theoretical representation of the reaction should be balanced well.
