What made Mendeleev certain that he should leave gaps in his table?
ser-zykov [4K]

Answer:

Mendeleev left gaps in his periodic table because he knew that these elements existed, but had not yet been discovered. He believed that the elements would be eventually found and would fit perfectly into the gaps. Two such elements are Germanium and Gallium.

How does wind cause weathering?
pantera1 [17]

Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!

The answer to your question is

D) Blowing sand can wear away a rock's surface and break it into smaller pieces

When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.

Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.

I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.

Please give me brainliest if I was correct and helpful!

Otherwise, please comment and let me know how I can fix my answer!

Thank you, it was fun, have a nice week!

If the total pressure of water vapor and hydrogen gas is 1.02 atm and the partial pressure of the water at 22.0 C is 0.13 atm, w
ira [324]

Answer:

0.89 atm  is the pressure of the hydrogen gas

Explanation:

We can use the molar fractions to solve this

Sum of molar fractions (hydrogen + water vapor) = 1

Molar fraction = Pressure gas / Total pressure

Molar fraction water vapor = 0.13 atm/1.02 atm = 0.127

1 - 0.127 = 0.873 (Molar fraction H2)

0.873 = Pressure H2 / Total pressure

0.873 = Pressure H2 / 1.02 atm

0.873 . 1.02atm = 0.89 atm
