What climate condition occurs during El Niño?

dry heat throughout North America
warm water moving toward the coast of South America
heavy rain moving toward the coast of South America
flooding throughout North America

Answers

Answer:

flooding throughout North America

Explanation:

An El Niño condition occurs when surface water in the equatorial Pacific becomes warmer than average and east winds blow weaker than normal. The opposite condition is called La Niña. During this phase of ENSO, the water is cooler than normal and the east winds are stronger. El Niños typically occur every 3 to 5 years.

Where is there higher air pressure, above the land or above the water?

Answers

Answer:

The air above land also warms faster than air above the sea. Cooler higher pressure air above the ocean moves toward warmer lower pressue air above land.

Answer:

Use the sources to help you, but I would say above the water.

Explanation:

"However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, high surface pressure will form because of the colder air."

AND

"The depth (distance from top to bottom) of the atmosphere is greatest at sea level and decreases at higher altitudes. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude."

I hope this helps you!

Use Boyle's Law to solve this problem: A gas has a volume of 10.0 L at a pressure of 4.0 atm. If the gas expands to 20.0 L, what will be the new volume, assuming that there is no change in moles or temperature.

Answers

Answer:

P₂ = 2 atm

Explanation:

Given data:

Initial volume = 10.0 L

Initial pressure = 4.0 atm

Final volume = 20.0 L

Final pressure = ?

Solution:

The given problem will be solved through the Boly'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

4.0 atm × 10.0 L = P₂ × 20.0 L

P₂ = 40.0  atm. L/ 20.0 L

P₂ = 2 atm

207g/mol

Explanation:

Given parameters:

Mass of the lead  = 41.4g

Number of moles  = 0.2mole

Unknown:

Molar mass of lead = ?

Solution:

The molar mass of substance is related to mass and number of moles using the expression below;

           Mass = number of moles x molar mass

        Molar mass = [tex]\frac{mass}{number of moles }[/tex]

Now insert the parameters and find the molar mass;

Difference between absolute atomic mass and relative atomic mass with example

Answers

“Atomic mass” is relative to the isotope carbon-12 weighing exactly 12 atomic mass units. Therefore “atomic mass” is precisely the same as “relative atomic mass.”

Two further points:

First, atomic mass as stated on the periodic table is a average of the masses of an element’s naturally-occurring isotopes, weighted by their abundance. This is because atomic mass as normally used is a bulk property: we weigh out many trillions of atoms at a time, because we usually deal in macroscopic quantities. And that means that an average mass is more useful to us.

Second, all masses are relative masses (until the new, physical-constant-based kilogram comes online; and arguably even then). We mass something by comparing it to some standard of reference: until later this year, that something is a chunk of alloy in Paris, France. When the new standard comes into use, we will be comparing the kilogram’s gravitational mass to the strength of the electromagnetic force.

But that’s kind of trivial; it just stems from the fact that any and every measurement is a comparison to something else.

Edit: IUPAC, the world’s premier organization for the imposition of picky definitions that most people never need to use, has the following:

Atomic mass is the mass of a single atom; the unit is the Dalton or unified atomic mass unit. (I would use “isotopic mass” to specify the mass of a particular atom, but that’s not sanctioned by IUPAC.)

Relative atomic mass is the measured average mass of all atoms of a particular element in a particular sample. To make it unitless, it’s divided by the value of the unified atomic mass unit.

Standard atomic weight is the value you read off of the periodic table; it’s an Earth-based average over many samples, of experimental values of the relative atomic mass. Values are promulgated by the IUPAC Commission on Atomic Weights and Isotopic Abundances, and are revised every two years.

Most chemists refer to standard atomic weight as “atomic mass” or “atomic weight” and get on with their lives.

The unified atomic mass unit is 1/12 of the mass of an atom of carbon-12. It is sometimes called the Dalton.

Definitions taken from the IUPAC Gold Book.

As far as I can tell, relative atomic masses and standard atomic weights are made unitless so that they can be used with any convenient macroscopic mass unit to determine correct proportions for a desired chemical reaction.

Answers

Answer:

Fractional distillation

Explanation:

Crude oil, also known as petroleum, is a naturally occurring substance found in the Earth's crust. It is a mixture of different useful substances. These substances are separated from one another based on their individual boiling points in a process called FRACTIONAL DISTILLATION.

The process of fractional distillation entails the application of heat to the crude oil. The different fractions evaporate and condense in the fractionating column depending on their boiling point. The hydrocarbon substances separated are called fractions, and they include bitumen, diesel, kerosene, gasoline, natural gas etc. Therefore, before we can use gasoline (petrol) in our cars, the crude oil needs to be separated into separate products like plastics and ink. This process is called FRACTIONAL DISTILLATION.

Where does the chemical energy to produce ATP come from

Answers

Answer:

glucose

Explanation:

Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available. The energy to make ATP comes from glucose. Cells convert glucose to ATP in a process called cellular respiration.

The chemical energy to produce ATP comes from the BREAKDOWN of carbon-based molecules into smaller molecules.

Cellular respiration is a series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP by using the energy stored in the chemical bonds of carbon-based molecules.

These reactions are catabolic reactions in which chemical bonds of larger molecules are broken down, thereby releasing energy.

These carbon-based molecules are glucose and fats (lipids).

Carbohydrates release 4000 calories (cal) per gram when they are burned during cellular respiration.

Conversely, fats (lipids) release approximately 9000 cal per gram when they are burned.

In conclusion, the chemical energy to produce ATP comes from the BREAKDOWN of carbon-based molecules into smaller molecules.

A student was assigned to take water samples from a lake near his home he measured the Ph of one of the water samples to be 6.0. which of the following best describes this sample of water
Highly acidic
Slightly acidic
Highly basic
Slightly basic

Answers

Answer:

B. Slightly acidic

Explanation:

pH can be defined as a measure of the negative logarithmic concentration of hydrogen ion (H+) in an aqueous solution.

Basically, the pH scale is used to measure the level of acidity or basicity of an aqueous solution based on a scale of 0 to 14.

An acidic solution has a pH lower than 7 (0 - 6), a basic solution has a pH higher than 7 (7 - 14) and a neutral solution has a pH of exactly 7.

In this scenario, a student was assigned to take water samples from a lake near his home he measured the Ph of one of the water samples to be 6.0. Therefore, this sample of water can be said to be slightly acidic its pH is slightly below 7.
