First, the amount of sunlight received at a given latitude is important. At the equator, the sun is high in the sky and thus very intense. As you move away from the equator, the sun does not reach as high of an angle in the sky, and is less intense. Another important effect near the poles is that during the summer, the sun is up all the time, which boosts the total amount of sunlight received in a day, while in contrast, during the winter, no sunlight is received at all.

There is another, more subtle effect that has to do with latitude. Nature likes to have the temperature be the same everywhere, much like ice cream melts at room temperature or a hot cup of coffee cools to room temperature. The equator is getting blasted with intense sunlight, while the poles are getting a lot less. Nature tries to resolve this imbalance and make the atmosphere the same temperature everywhere. The most efficient way to transfer heat towards the poles depends on latitude and the rotation of the Earth in a complex way. In the tropics (within 30 degrees latitude of the equator), the average daily temperature is mostly constant. Whether you move from north to south, say fro the equator to Mexico, the temperature is mostly the same. Compare that to the midlatitudes (30–60 degrees latitude), where the temperature changes rapidly as you move north or south to the poles. For example, the temperature in Texas is a lot hotter than the temperature in North Dakota.

Another factor is the composition of the surface. Different substances absorb, store, and re-emit heat with different levels of efficiency. The ocean is a major factor, which can either warm or cool the adjacent land. Other surface materials like rock, sand, vegetation, and ice also regulate temperature

The elevations of the surface, specifically mountains effect the climate. Usually, the taller the mountain, the colder the temperature is at the top. Mountains also cause air to flow in certain ways around them, which leads to wet areas on the upwind side and dry areas on the downwind side.

Explanation:

T he cool thing about the periodic table is the way it is organized. You can find chemical with similar properties is just looking in the column they are in in to determine the answer. Since Na is in the first column, any of these answer can work:

Li, K, Rb, Cs, and Fr

Answer:

17550g

Explanation:

You want to use the equation D=M/V. You are given density in g/mL, so you just need to multiply that by 9L, but first you want the mL and L to match, so you change the 9L to 9000mL (knowing there is 1000mL in 1L). Then solve algebraically by multiplying the 9000mL and the 1.95g/ml, making the mL cancel, leaving you with your answer in grams.

Hope this helps!

Answer:

I think it's is because during osmosis because when the cell duplicates in osmosis it divides into two smaller daughter cells; in diffusion there is a higher concentration near where it is but its getting smaller particles from where the source is

Answer:

The molecular structure affects solubility mainly biased on its polarity or bonded ions.

Explanation:

Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.

**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

Answer:

the correct answer is CO2 (the last one)

3.125g

Explanation

2.4 minutes = 1 half life

so 12 minutes = 5 half lives (12/2.4)

100g/2 = 50g (1 half life)

50g/2 = 25g (2 half lives)

25g/2 = 12.5g (3 half lives)

12.5g/2 = 6.25g (4 half lives)

6.25g/2 = 3.125g (5 half lives)

Answer:

That's pretty easy,if you have a grasp of Elements, Compounds and their Symbols ans Molecular formula.

So, Let's get started!

Our reactions are as follows:

Think of a compound that has both Sodium and Chlorine and is very common.

Common salt — Sodium chloride!

Yeah, that's it! It has both Sodium and Chlorine in it's molecular formula. (NaCl)

Now, we have to, somehow, get Magnesium oxide using Oxygen. The best way is: by reacting Magnesium with Oxygen.

Now, we have to get two reactants that react to form Iron Sulfide.

FeS contains only two elements in its formula and that are: Iron(Fe) and Sulfur(S).

So, the best way would be to react Iron(Fe) and Sulfur(S) and get Iron Sulfide (FeS)

You must know that water is H2O, that is, a compound of Hydrogen and Oxygen, the easiest way to get H2O as your product would be : by reacting Oxygen and Hydrogen.

The empirical formula for trichloroisocyanuric acid, the active ingredient in many household bleaches, is OCNCl. The molar mass of this compound is 232.41g/mol.

Answer:

metallic bond, force that holds atoms together in a metallic substance. The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.

Explanation:

Answer:

element

Explanation:

A metal is an element that readily forms positive ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons

Answer:

Metal is an element because it consist of type of atom and can't be divided into other substance .

You can simply subtract the atomic number from the mass number in order to find the number of neutrons.

it's 3 dollars per 12 eggs so 3/12

simplify 3/12 by dividing both numbers by 3 so you get 1/4

you should know what 1/4 of a dollar is

or think of it this way 12 eggs are 3 dollars so every 4 eggs is one dollar. divide 1 dollar by 4 eggs

The total pressure in the flask measured at 400 K is 1 atm

The correct answer to the question is Option B. 1 atm

From the question given above, the following data were obtained:

Using the ideal gas equation, we can obtain the pressure in the flask as follow:

PV = nRT

P × 1 = 0.03 × 0.082 × 400

Therefore, the total pressure in the flask measured at 400 K is 1 atm

Answer: a: 3 atm

Explanation:

0.03 mol NH4NO3 decomposes into 0.09 mol of gas total, thus we multiply 0.09 by 0.082 and 400K to get our answer of about 3 atm.

Answer: Adding or removing energy from matter

Explanation:

Answer:

a. NP

b. NP

c. Polar

d. Ionic

e. Polar

Explanation:

The way I did it was using the electronegativity of the elements mentioned and subtracted the pairs. For non polar the difference is 0-0.4, for polar it’s 0.4-2.0, for ionic it’s >2.0. I included the chart I used to find the electonegativity for the elements below.

B: 2.04, P: 2.19, difference is 0.15, so NP

Be: 1.57, Si: 1.9, difference is 0.33, so NP

C: 2.55, Na: 0.93, difference is 1.62, so Polar

Li: 0.98, O: 3.44, difference is 2.46, so Ionic

Mg: 1.31, N: 3.04, difference is 1.73, so Polar
