A substance has a triple point at −24.5 ∘C and 225 mmHg. What is most likely to happen to a solid sample of the substance as it

is warmed from −35 ∘C to 5 ∘C at a pressure of 210 mmHg?
Nothing (the solid will remain as a solid).
The solid will sublime into a gas.
The solid will melt into a liquid.

Answer:

Solid will sublime into a gas.

Explanation:

Triple point is a temperature where the three states of a substance coexist.

If the pressure is lower than the triple point, the substance does not exist as a liquid, so it is impossible that solid melts, or that the solid remains as a solid.

Liquid state is not stable.

Answer:

0.58 atm

Explanation:

Step 1: Given data

  • Total pressure of the gaseous mixture (P): 1.05 atm
  • Partial pressure of N₂ (pN₂): 0.35 atm
  • Partial pressure of H₂ (pH₂): 0.12 atm
  • Partial pressure of CO₂ (pCO₂): ?

Step 2: Calculate the partial pressure of CO₂

The total pressure of the gaseous mixture is equal to the sum of the partial pressures of the individual gases.

P = pN₂ + pO₂ + pCO₂

pCO₂ = P - pN₂ - pO₂

pCO₂ = 1.05 atm - 0.35 atm - 0.12 atm = 0.58 atm

Here is Beck's address:
777dan777 [17]

Hi! My answer would be D, USA.


Explanation:


We are provided with 5 pieces of an address. They are as followed.

12 Riverdale Lane, Apartment A, San Jose, California, and USA.


Imagine each of the five parts of Beck's address represents Earth, the Milky Way, the moon, the solar system, or the universe, based on their sizes. Which of the following parts of Beck's address would represent the solar system?



If we have to plug in Earth, the Milky Way, the moon, the solar system, and the universe, (all based on size,) we would first start with what "Apartment A" would be in this scenario. Apartment A is the smallest piece we have to work with, and so is the moon. This leads me to believe that the Moon should be plugged into Apartment A. Now, 12 Riverdale Lane is most likely going to be the Earth, since it is the second smallest one on our list. San Jose would turn into the Sun, California represents the Milky Way, and USA represents the solar system.


I sincerely hope I helped!


Have a wonderful day :)
