Answers

Answer:

The number of degrees of longitude that separates New York City from Denver, Colorado is 30.9843 degrees longitude

Explanation:

The longitude of New York City is 74.0060° W

The latitude of New York City is 40.7128° N

The longitude of Denver, Colorado is 104.9903°W

The latitude of Denver Colorado is 39.7392°N

Therefore, the difference the number of degrees of longitude that separates New York City from Denver, Colorado is 104.9903 - 74.0060 = 30.9843°.

Describe the process of evaporation condensation, and precipitation

Answers

Answer:

eva... water to gaseous foum .... condensation liquid to solid and perp ..... water that is falling out of the sky, this could be rain, drizzle, snow, sleet, hail or something rarer!

Answer:

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. Condensation is the process by which water vapor in the air is changed into liquid water.

Explanation:

A newspaper article about the danger of global warming from the accumulation of greenhouse gases such as carbon dioxide states that "reducing driving your car by 20 miles a week would prevent release of over 1000 pounds of CO2 per year into the atmosphere." Is this a reasonable statement? Assume that gasoline is octane (molecular formula is C8H18) and that it is burned completely to CO2 and H2O in the engine of your car. Facts (or reasonable guesses) about your car's gas mileage, the density of octane, and other factors will also be needed.

Answers

Answer:

The newspaper article's statement is correct since the mass of CO₂ reduced = 1071.85 pounds

Explanation:

Equation for the combustion of gasoline (octane) is given below:

2C₈H₁₈ + 25O₂ ---->  16CO₂ + 18H₂O

Density of C₈H₁₈ = 0.8 g/mL

Assuming mileage of the car is 20 miles/gallon; 1 gallon = 3.785 L

Since 20 miles is reduced in driving each week, thereby saving 1 gallon of gasoline, number of litres of gasoline reduced in a year is given by;

52 * 3.785 L = 196.82 L = 196820 mL

density = mass/volume; mass = density * volume

mass of gasoline saved = 0.8 g/mL * 196820 mL = 157456 g

number of moles = mass/molar mass

Molar mass of C₈H₁₈ = 114  g/mol

number of moles of C₈H₁₈ in 157456 g = 157456 g / 114 g/mol = 1381.2 moles

From the equation of reaction, 2 moles of C₈H₁₈ produces 16 moles of CO₂

1381.2 moles of C₈H₁₈ will produce 1381.2 * 16/2 moles of CO₂ = 11049.6 moles of CO₂

mass = number of moles * molar mass

molar mass of CO₂ = 44 g/mol

mass of CO₂ = 11049.6 moles * 44 g/mol = 486182.4 g

1 g = 0.00220462 pounds

Therefore mass of CO₂ reduced = 486182.4 g * 0.00220462 lb/g

mass of CO₂ reduced = 1071.85 pounds

Therefore, the newspaper article's statement is correct

Which element is not conserved in this unbalanced chemical equation?
2NaOH + H2S04 - NaSO4 + 2H20
Ο Α. Η
O B. S
O c. O
O D. Na

Answers

D. Na

There are 2 Na in the reactants, and only 1 Na in the product.

In the given unbalanced reaction, the number of sodium is not balanced. There must have two sodium in the product side also. The correct formula of sodium sulphate is Na₂SO₄.

What is mass conservation law?

According to the law of conservation of mass, the total mass of a system is conserved. Thus, mass can neither be created nor be destroyed. Therefore, for a chemical reaction, the total mass in the product side must be equal to the total mass in the reactant side.

The balanced equation of  a chemical reaction thus, obeying the mass conservation law where, each element have to be equal in number in both sides.

In the given reaction, the number of Na in reactant side is 2 and that in product side is 1 only. Thus total mass of sodium is not conserved. It can be corrected as Na₂SO₄ in the product side.

An isotope of Cesium -137 has a half-life of 30 years. If 1.0 g of Cesium – 137 disintegrates over a period of 60 years, how many grams of Cesium- 137 would remain?

Answers

Answer:

Explanation:

Radioactive decay follows the equation:

Ln [A] = -kt + ln [A]₀

Where [A] is amount of isotope after time t: Our incognite,

k is rate constant: ln 2 / Half-life = 0.0231 years⁻¹

t are 60 years

[A]₀ is initial amount of isotope: 1.0g

Replacing:

Ln [A] = -kt + ln [A]₀

Ln [A] = -0.0231 years⁻¹*60 years + ln 1.0g

ln [A] = -1.386

[A] = 0.25g

Which method of heat transfer is the person in the picture below most worried about?

Answers

Answer:

Radiation ...........

Hey There!_____________________________________Answer:

[tex]\huge\boxed{Conduction}[/tex]

_____________________________________Conduction:

Conduction is the transfer of heat when two things come in contact with each other. The energy transfer is from hotter body to the colder body.

                                x---------------------------------------------x

Fire Walking:

There is a trick behind fire-walking. When the coal burns, after sometime there is a layer of ash on the surface of the coal which blocks the radiation. So the transfer of heat is not possible from radiation. Conduction is the only way possible. The person's feet and coal both are poor conductor of heat so if we walk quickly i.e. there is minimal time of contact with the coal, it will just feel a little warm. As the person start walking on the coal, It has to do it quickly, that way Person will feel its sole warming up but it is not that hot because of the layer of ash and poor conductance, after few steps the ash also sticks on to the sole of the person which makes kind of double layers of ash. So the only way for heat transfer is CONDUCTION.

Explanation:

The part of the human body that has the same role as the power source in a computer is the heart. A power source in a computer provides energy that powers the whole system.

The human heart provides the pumping action for the circulatory system. Just like current passes through wires in a computer by energy from the power source, the human heart pumps blood throughout the body in a like manner. Without the pumping action of the heart, the human body is dead.

Also, keyboard and mouse are input devices. They are used to give instruction and perform certain tasks on the computer system.

The human body can also carryout tasks by using the hand. Objects are moved from one place to another just as you drag an icon using the mouse. We type word processors using information from the keyboard, also, we are able write using pen on paper.

the final answer and unit.
Show Your Work

Answers

Answer:

P = 34.1 L

Explanation:

Given data:

Number of moles = 10 mol

Volume occupy = 15 L

Temperature = 350°C

Pressure of gas = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

Now we will convert the temperature.

350+273 = 623 K

by putting values,

P×15 L = 10 mol ×0.0821 atm.L/ mol.K ×623 K

P = 511.48atm.L/15L

P = 34.1 L

What is light?

Light, often known as visible light, is electromagnetic radiation that falls within the region of electromagnetic wave or spectrum that the human eye can perceive.

White is a mixture of all seven colors found in the white light spectrum, including Violet, Indigo, Blue, Green, Yellow, Orange, and Red. This visible spectrum has a wavelength of 400 to 700 nanometers. When an object appears to be a particular color, such as red, it signifies that it is projecting the wavelength of red light  (620 to 750 nanometers) while absorbing all other wavelengths. Furthermore, because  light is a kind of energy, the more light a thing consumes, the more heat it consumes.
