Can you locate any mountains in the tropical zones?
krek1111 [17]

Answer:

At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra. The largest and highest area of mountain lands occurs in the Himalaya -Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south.

8. Zeolite is used to remove moisture from methane. A vertical column is filled with 1000.0 kg of dry zeolite. The zeolite has t
Natasha_Volkova [10]

Answer:

Follows are the solution to this question:

Explanation:

Methane inlet humidity content of =7.00\%

Methane moisture outlet content =0.05\%

Zeolite absorption humidity = 6.95\%

Dry zeolite 1 kg will accommodate water= 0.1000 \ kg

One kilogram of Dry Zeolite will carry water from =0.1000\ kg

The water can contain 1000 kg of zeolite = 100 \ kg

Methane which would be made =\frac{100}{6.95\%}= 1,439 \ kg

That's why it will be producing 1439 kg of methane.

What is the molarity of 10.0 g of NaCl dissolved in water to make 100. mL?
tigry1 [53]

Answer:

=<em><u> 1.7 M</u></em>

Explanation:

Molecular mass of NaCl = ( 23+35.5 ) = 58.5g

58.5g of NaCl are weighed by 1 mole of NaCl

10.0g of NaCl will be weighed by ( 10÷58.5 )

<em> <u>= 0.17 moles of </u><u>NaCl</u></em>

100mL = ( 100÷1000)L = 0.1L

0.1L of a solution is occupied by 0.17 moles of NaCl

<u>1L</u> of solution will be occupied by [(1÷0.1)×0.17]

=<em><u>1</u></em><em><u>.</u></em><em><u>7</u></em><em><u> </u></em><em><u>M</u></em>

The brightness of a star is most dependent on the star's...Explain why.
gulaghasi [49]
I would say the answer is A - a stars mass

The majority of stars in the galaxy, including our Sun, Sirius and Alpha Centauri A and B are all main sequence stars.


Mass is the key factor in determining the lifespan of a main sequence star, its size and its luminosity ( brightness)




Two characteristics define brightness: luminosity and magnitude. Luminosity is the amount of light that a star radiates. The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth.
