The summit of mount Everest is at 29,029 feet. At this elevation the atmosphere pressure is 30 kPa or about 0.30 atm. What is the boiling point of water at the top of mount Everest
The boiling point of water is 341.74K
Data Given;
height = 29,029 ftpressure(p) = 30kpa = 0.30atmT1 = 100^oC or 373KH(vap) = 43653 kJ/molThe formula to solve this problem is
[tex]ln(\frac{1}{p}) = \delta H/R (\frac{1}{T_1} - \frac{1}{T2}) [/tex]
We can solve for the final temperature here;
[tex]In(1/0.3) = 40653/8.314(\frac{1}{373}-\frac{1}{T_2}) [/tex]
[tex]ln(3.33) = \frac{4809.47}{T_2} - 13.108\\ T_2 = 341.72K = 69^0C[/tex]

4 KO2 + 2 CO2 = 2 K2C03 + 302
How many grams of KO, are needed
to produce 100 g of O2?
Please explain how to solve
Answer:
4KO₂ + 2CO₂ -> 2K₂CO₃ + 3O₂
Step 1: Find the moles of O₂.
n(O₂) = mass/ Mr.
n(O₂) = 100 / 32 = 3.125 mol
Step 2: Find the ratio between KO₂ and O₂.
KO₂ : O₂
4 : 3
4/3 : 1
(4*3125)/3 : 3.125
=4.167 mol of KO₂
Thus now we know, to produce 100 g of O₂, we need 4.167mol of KO₂
Step 3: Find the mass of KO₂:
mass = mol * Mr. (KO₂)
Mass = 4.167* 71.1
Mass = 296.25 g

Based on their activation energies and energy changes and assuming that all collision factors are the same, which of the following reactions would be fastest in the reverse direction?
A) Ea= Ea3 = 54 kJ/mol , ΔE= ΔE3 = 8 kJ/mol .
B) Ea= Ea2 = 36 kJ/mol , ΔE= ΔE2 = -10 kJ/mol .
C) Ea= Ea1 = 45 kJ/mol , ΔE= ΔE1 = -25 kJ/mol .
D) Ea= 36 kJ/mol , ΔE= ΔE2 = -10 kJ/mol and Ea= 54 kJ/mol , ΔE= ΔE3 = 8 kJ/mol
The reaction that has the fastest rate of reverse reaction is the one in which Ea= Ea3 = 54 kJ/mol , ΔE= ΔE3 = 8 kJ/mol (Option A).
What is activation energy?The term activation energy refers to the minimum energy that reactants must possess in order for their collision to result in a chemical reaction.
The higher the activation energy, the faster the reverse reaction. Hence the reaction that has the fastest rate of reaction is the one in which Ea= Ea3 = 54 kJ/mol , ΔE= ΔE3 = 8 kJ/mol (Option A).

Which of the following is the main reason that Pluto is not a planet?
1. It does not have the correct coloration.
2. It does not have a rocky surface.
3. It doesn't orbit the sun
4. Its orbit overlaps with another planets' orbit.
(My sis needs help)
Answer:
4. Its orbit overlaps with another planets' orbit
Explanation:
While this is the right answer, it isn't worded very well so instead of explaining why this answer is right, I will explain why the other answers are wrong.
Coloration has nothing to do with an object in space's eligibility to be classified as a planet.
Planets don't need to have a rocky surface (look at the gas giants such as Saturn or Jupiter for example)
And like everything else in our solar system, Pluto orbits the sun.

Explain why different colors are emitted when different metals are hearted?? Please someone answer this
Answer:
Different elements emit different colors when heated because their electrons have different allowed energy levels according to the element.
Explanation:
When you heat up an atom it's electrons are stimulated and sort of leap to a higher level of energy, and when they calm down, they emit a new energy that shows in the form of light. However, the color wholly depends on the difference in energy between the two levels of energy, every element has a different number in electrons, so therefore there is more range in energy levels, giving each individual element its own specific range of colors. Though it's normally a subtle difference, every elements color range is as unique as a snowflake or a person's fingerprints.
