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

Which of the following does not apply to water molecules?

Water molecules are polar
Water has cohesive properties
Water is less dense as a solid than a liquid
Water is not a very good solvent

Answers

Answer:

It is the last one.

Explanation:

Water molecules are polar, they have cohesive properties, and water is less dense when it is solid than when it is a liquid, that is why ice floats in liquid water. However, water is a very good solvent, it can dissolve many solids, including sugar, salt, and other hydrophilic substances.

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

Radiation

Conduction

Convection

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.

How many grams are equal to 0.11 mole of copper(I) chromate?

Answers

Mass of Copper(I) chromate( CuCrO₄) = 19.75 g

Further explanation

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

[tex]\tt \large{\boxed{\bold{mol=\dfrac{m(mass)}{MW(molecular~weight)}}}[/tex]

0.11 mole of Copper(I) chromate( CuCrO₄) ⇒ MW=179.54 g/mol, so mass :

[tex]\tt mass=mol\times MW\\\\mass=0.11\times 179.54\\\\mass=19.75~g[/tex]

1. What part of the human body has the same role as the power source in a computer?

2.What part of the human body has the same role as the keyboard or the mouse on a computer?

Answers

Answer:

The heart

Hand

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.

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
