Answer:

Vapor Information

Explanation:

Atmospheric rivers are relatively long, narrow regions in the atmosphere like rivers in the sky that transport most of the water vapor outside of the tropics. Not all atmospheric rivers cause damage, and most are weak systems that often provide beneficial rain or snow that is crucial to the water supply.

Answer:

??????????

Explanation:

Based on the information given, the image represents a negatively charged fluoride atom (Option B)

An atom is composed of a centrally placed nucleus (containing protons and neutrons) and a cloud of electrons revolving round it.

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

Charge = Proton – Electron

Charge = 9 – 10

Charge = –1

Note

Element with proton number of 9 is fluorine

Thus, we can conclude that the image represents a negatively charged fluoride ion (Option B)

Answer:

B

Explanation:

Answer:

56.94759 grams of NO2

Explanation:

Stoichiometric Equation:

1 S + 6 HNO3 → 1 H2SO4 + 6 NO2 + 2 H2O.

This is so you can create ratios between each compound in the reaction, and identify the limiting and excess reactants to determine exactly how much can be produced?

The coefficients or molecular quantity of each compound in the balanced equation represents the amount of moles.

To figure out how much can be produced, you have to convert 59.54 g of S into moles of S and 78 g of HNO3 into moles of HNO3.

A reference such as a periodic table can be very helpful as it has the atomic mass of each element which is the mass with respect to 1 mol of that element.

Answer:

[tex]206.6\ \text{kPa}[/tex]

Explanation:

[tex]P_1[/tex] = Initial pressure = 200 kPa

[tex]P_2[/tex] = Final pressure

[tex]T_1[/tex] = Initial temperature = [tex]30^{\circ}\text{C}[/tex]

[tex]T_2[/tex] = Final temperature = [tex]40^{\circ}\text{C}[/tex]

We have the relation

[tex]\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=\dfrac{T_2}{T_1}P_1\\\Rightarrow P_2=\dfrac{40+273.15}{30+273.15}\times 200\\\Rightarrow P_2=206.6\ \text{kPa}[/tex]

The pressure that would be exerted after the temperature change is [tex]206.6\ \text{kPa}[/tex].

Answer:

Oxidation - reduction reaction which is called redox reaction.

Explanation:

The type of reaction that is a part of another type but treated separately is called Oxidation - reduction reaction.

Thus is because they usually involve 2 separate half reactions which are oxidation reactions that involve loss of electrons and then reduction equations which involve gain of electrons.

They are treated separately for example when sodium reacts with chlorine to form sodium chloride.

2Na + Cl2 = 2NaCl

Now, sodium undergoes oxidation by loosing elctrons and it's half reaction is;

2Na → 2Na​^(+) + 2e^(-)

​​Meanwhile chlorine undergoes reduction by gaining electrons and its half reaction is;

Cl2 + 2e^(-) → 2Cl^(-)

Answer:

See explanation

Explanation:

The most important thing to bear in mind when writing chemical reaction equation is that the equation must be balanced. A balanced chemical reaction equation is one in which the number of atoms of each element on the left and right hand sides of the reaction equation is exactly the same.

Answer:

the main use of coal in the United States is to generate electricity.

Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons

Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Answer:

P = 13.5 atm

Explanation:

Given that

No. of moles, n = 20 moles

Volume of nitrogen gas = 36.2 L

Temperature = 25°C = 298 K

We need to find the pressure of the gas. Using the ideal gas equation

PV = nRT

Where

R is gas constant, [tex]R=0.082057\ L-atm/K-mol[/tex]

So,

[tex]P=\dfrac{nRT}{V}\\\\P=\dfrac{20\times 0.082057\times 298}{36.2 }\\\\P=13.5\ atm[/tex]

so, the pressure of the gas is equal to 13.5 atm.

Answer:

A- Upwelling

Explanation:

To solve this we must have a claeas concept behind Farsightedness and nearsightedness. Therefore, distant objects are blurry,  describes farsightedness. The correct option is option A.

Farsightedness (hyperopia) is a common visual issue in which you can clearly see far things but have fuzzy vision of nearer items. Your capacity to focus is affected by your degree of farsightedness.

Farsightedness is most usually caused by an eyeball that is too short or by a cornea (the transparent layer at the front of the eye) that is not curved enough. Light cannot focus directly on the retina due to these two issues. Light instead concentrates behind the retina, making close-up objects appear fuzzy.

Therefore, distant objects are blurry,  describes farsightedness. The correct option is option A.

Answer:

A-B : solid wax heating

B-C : melting

C-D : liquid wax heating

D-E : Boiling

E-F : Gaseous wax heating

A sample of solid candle wax is put into a pot on the stove. Heat energy is transferred to the wax at a constant rate by the burner on the stove. A-B is solid wax heating, B-C is melting, C-D is liquid wax heating, D-E is Boiling and E-F is Gaseous wax heating.

A heating system is a device that uses thermal energy to keep indoor temperatures within a house, workplace, or other structure at a comfortable level. portion of an HVAC system frequently. A heating system can be dispersed or centrally located.

The movement of minuscule atoms, molecules, or ions in solids, liquids, and gases produces heat energy. From one thing to another, heat energy can be exchanged. Heat is the flow or transfer that occurs as a result of the temperature differential between two objects.

When heat is applied to some substances, chemical changes or reactions occur that result in the formation of one or more new compounds with unique features.

Thus, A-B is solid wax heating, B-C is melting, C-D is liquid wax heating, D-E is Boiling and E-F is Gaseous wax heating.
