how does the ocean affect the climate of nearby mountain ranges ?

give me a good paragraph ! for extra points pls

Answers

Answer:

Prevailing winds (sea breeze) from the ocean push warm moist air against the mountain & it moves up. As the moist air rises, it begins to get cooler and cooler due to the high altitude. ... Dry Air Since the air already lost its moisture, the humidity on this side is low & plants get very little water.

Explanation:

The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years t

What is depicted in a molecular formula?

Answers

Answer:

Molecular formula describes about number of atoms of each constituent element present in any molecule.

Explanation:

Molecular formula describe about the number and type of atoms in any molecule.  A molecular formula is not a chemical name but instead it is a chemical formula of a compound. A molecular formula consist of chemical symbols for constituent elements followed by numeric subscripts which tells us about number of atoms of each element present in a molecule. For example : Ammonia is a compound of nitrogen and hydrogen i.e NH₃ . As there is only one N atom so we have written only N in it's molecular formula. But as there are 3-H atoms so we have written subscript 3 in H symbol in it's molecular formula. Molecular formula does not tell us anything about shape of molecule .

6. Why does DNA need to be organized into chromosomes before cell division?
The DNA would be too difficult to separate without this organization.
The DNA would take up too little space without this organization.
The DNA would be pulled apart rapidly without this organization.
The DNA would be broken without this organization.

Answers

Answer:

The DNA would be too difficult to separate without this organization.

Explanation:

DNA is usually wrapped loosely, but when ready to divide it wraps tighter. It's so each chromosome is a distinct unit. When the cell divides one copy goes to each of the resulting cells. If not lined up properly sereve genetic issues can occur. Chromosome alignment makes the process more efficient.

Calculate the new volume if a 13.40 L of a gas at a pressure of 1.51 atm is subject to a new pressure of 65 mmHg.

Answers

Answer:

V₂ = 238.05 L

Explanation:

Given data:

Final volume = ?

Initial volume = 13.40 L

Initial pressure = 1.51 atm

Final pressure = 65 mmHg ( 65/760 = 0.085 atm)

Solution:

The given problem will be solved through the Boyle's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

1.51 atm × 13.40 L = 0.085 atm × V₂

V₂ = 1.51 atm × 13.40 L /  0.085 atm

V₂ = 238.05 L

When placed in distilled water, the pH of metal oxides will be?

Less than 7

Equal to 7

greater than 7

neutral ​

Answers

Neutral they’re equal

When placed in distilled water, the pH of metal oxides will be greater than 7. The correct option is C.

What are metal oxides?

Metal oxides are crystalline solids containing both a metal cation and an oxide anion. In most cases, they react with water to form bases or with acids to form salts.

Metal oxides are compounds that contain two elements, namely a metal and an oxygen atom. Examples include sodium oxide (Na2O), magnesium oxide (MgO), calcium oxide (CaO), and others.

When metal oxides react with dilute acids, they form salt and water, demonstrating that they are basic.

Metal oxides are alkaline. When we dissolve them in water, we get solutions with pH values higher than 7. The reaction between a nonmetal and oxygen produces nonmetal oxides. Nonmetal oxides are highly acidic.

Thus, the correct option is C.

Find the number of moles if you have 1.2 x 1048 copper atoms.

Answers

Answer:

Explanation:

From avogadro's number, we have that;

1 mole of atoms contain 6.022 × 10^(23) atoms

Therefore, 1.2 x 10^(48) atoms of copper will contain;

(1.2 x 10^(48) × 1)/(6.022 × 10^(23)) = 1.993 × 10^(24) moles
