Which of these is an example of interactions between the atmosphere and hydrosphere? (3 points) formation of snow cracking of rocks due to heat destruction of houses by wind uprooting of trees during tornadoes

Answers

Answer 1

Answer:

A. formation of snow

Explanation:

The formation of snow is an example of interactions between the atmosphere and hydrosphere.

As snow formation takes place when water vapor converted into liquid through condensation in the clouds. As water droplets rises high in clouds, cooler air present in atmosphere allow to lower the temperature and water droplets form ice or snow.

Hence, the correct option is A.

these are easily extracted with a pH solution of greater than 7? which one

A) acid drugs
B) metabolites
C) base drugs
D) derivatives

Answers

Answer:

base drugs

Explanation:

The pH scale is a scale graduated from 0-14. It is used as an indicator of the degree of acidity or alkalinity. A pH of 0-6.9 indicates acidity. A pH of 7 indicates that the solution is neutral. A solution of pH above 7 indicates that the substance is basic.

It is thus a correct statement to say that any substance that dissolves in solution to produce a solution of pH greater than 7.0 is a basic substance.

If we look at the options closely, it is only a basic drug that will dissolve in water to yield a basic solution of pH greater than 7.0 hence the answer.

B.metallic is the answer hope this helped

The correct answer is option B. Metallic.

What explains the structure of metals and delocalized electrons?

Metal is composed of a huge structure of atoms arranged in a regular pattern. Electrons from the outer shell of a metal atom are delocalized and can move freely throughout the structure. This sharing of delocalized electrons results in strong metal bonds.

Metallic bonds are electrostatic attraction between metal cations and the negatively charged ocean of delocalized electrons. The sea of ​​delocalized electrons contains only valence electrons, not core electrons.

HSAB concept( Pearson acid-base concept) is an initialism for "hard and soft (Lewis) acids and bases"

So F- is a Halogen which is a Hard Base

And OH- is a Hard base as well

And H- is a soft base

So soft acids react best with soft bases and hard acids react best with hard bases.

Bases don't react with other bases.

hi:) how to do 2(bi)?

Answers

Answer:

4 protons, 5 neutrons, 2 electrons

Explanation:

If you look at the numbers beside Be²⁺, the number 9 is the relative atomic mass and the number 4 is the proton (atomic) number. The relative atomic mass is the sum of the number of protons and the number of neutrons.

Number of protons= proton number.

Hence, number of protons= 4

Number of protons + neutrons= 9

4 + number of neutrons= 9

number of neutrons

= 9 -4

= 5

In an atom, the number of protons and electrons are the same since atoms are electrically neutral. But in an ion, the number of electrons is not equal to the number of protons since the atom gains/ loses electrons to form an ion. A positive sign means that electrons are given away.

Thus, Be gives away 2 electrons to form Be²⁺.

Original number of electrons= 4

Number of electrons in Be²⁺

= 4 -2

= 2

In summary, the number of protons and neutrons in an ion is the same as that of the atom. However, the number of electrons is not the same.

Number of protons= proton number.

Answer : The boron-11 isotope is the most abundant.

Explanation :

As we are given that:

Average atomic mass of boron = 10.81 amu

Mass of boron-10 = 10.0129 amu

Mass of boron-11 = 11.0093 amu

As we know that the average atomic mass of an element is always closest to the most abundant isotope.

Out of the two boron isotopes, B-11 is closest in mass to the weighted average. Therefore, it is the most abundant.

Hence, the boron-11 isotope is the most abundant.

The topmost layer of the Earth is made up of large pieces that fit together like a puzzle. However, these pieces don't stay still, and sometimes they rub against each other. When these large sections of the Earth’s crust, called tectonic plates, hit each other, they send vibrations through the surface of the Earth. These vibrations are seismic waves. Seismic waves are just like the ripples in a pond. But instead of traveling through water, they travel through the Earth. When they reach the Earth's surface, they make the ground shake. That's an earthquake.

How many grams of aluminum oxide would be produced from the reaction of 0.25 grams of aluminum with excess oxygen gas?

Answers

Answer:

0.472 grams of aluminum oxide would be produced from the reaction of 0.25 grams of aluminum with excess oxygen gas.

Explanation:

First of all, you should know that the balanced reaction that occurs:

4 Al + 3 O₂ → 2 Al₂O₃

Then, by stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts are produced in moles:

Al: 4 molesO₂: 3 molesAl₂O₃: 2 moles

Being:

Al: 27 g/moleO: 16 g/mole

The molar mass of the compounds participating in the reaction is:

Al: 27 g/moleO₂: 2*16 g/mole= 32 g/moleAl₂O₃: 2*27 g/mole + 3*16 g/mole= 102 g/mole

Then, by stoichiometry of the reaction, the following amounts of mass react and are produced:

Al: 4 moles*27 g/mole= 108 gO₂: 3 moles*32 g/mole= 96 gAl₂O₃: 2 moles*102 g/mole= 204 g

 

Now it is possible to apply the following rule of three: if 108 grams of Al produce 204 grams of Al₂O₃, 0.25 grams of aluminum how much mass of Al₂O₃ will it produce?

[tex]mass of Al_{2} O_{3} =\frac{0.25 grams of Al*204 grams of Al_{2} O_{3} }{108 grams of Al}[/tex]

mass of Al₂O₃=0.472 grams

0.472 grams of aluminum oxide would be produced from the reaction of 0.25 grams of aluminum with excess oxygen gas.

Answer:

15. 2.66 moles .

16. 2.09L.

Explanation:

Molarity of a solution is simply defined as the mole of solute per unit litre of the solvent. Mathematically, it is represented as:

Molarity = mole /Volume.

With the above formula, let us answer the questions given above

15. Data obtained from the question include the following:

Volume of solution = 1.4L

Molarity = 1.9M

Mole of solute =.?

Molarity = mole /Volume

1.9 = mole / 1.4

Cross multiply

Mole = 1.9 x 1.4

Mole = 2.66 moles

Therefore, the mole of the solute present in the solution is 2.66 moles.

16. Data obtained from the question include the following:

Mole of solute = 0.46 mole

Molarity = 0.22M

Volume of solvent (water) =.?

Molarity = mole /Volume

0.22 = 0.46/Volume

Cross multiply

0.22 x Volume = 0.46

Divide both side 0.22

Volume = 0.46/0.22

Volume = 2.09L

Therefore, 2.09L of water is required.

B.the speed at which oxygen is returned to blood in the lungs
C. the force with which the ventricles contract
D. the rate at which blood flows through the heart

Answers

Answer:

C

Explanation:

What causes blood pressure?

C

To pump blood around the body, the heart contracts and then relaxes through the cardiac cycle. The cycle begins with the contraction of the two atria, which push blood into the ventricles. Then, the ventricles contract, which forces the blood out of the heart.

When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure.

When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.

Avogadro's Law is stated mathematically as follows: Vn=k, where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant

Avogadro's Law is stated mathematically as follows: Vn=k, where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant.

What is Avagrado's law?

According to Avogadro's Law, all gases have an identical number of molecules in an equal volume at a given temperature and pressure. Amedeo Avogadro, an Italian chemist and physicist, first described the law in 1811.

At 0 °C and 1 abm pressure, the molar volume of all ideal gases is 22.4 litres.  If a gas's temperature and pressure remain constant, its volume will also grow as its amount increases.

If a gas's pressure and temperature are both constant, its volume falls as its volume of gas does. Every time you blow a balloon up, you demonstrate Avogadro's Law.

Therefore, Avogadro's Law is stated mathematically as follows: Vn=k, where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant.
