Answer:

hydrochloric acid

Explanation:

These anions usually have the ending “-ide.” As acids, these compounds are named starting with the prefix “hydro-,” then adding the first syllable of the anion, then the suffix “-ic.” For example, HCl, which is hydrogen and chlorine, is called hydrochloric acid. More complex acids have oxygen in the compound.

Answer:

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

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

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

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.

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°.

There are 20.8 moles of propanol

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

1.2 x 10⁵ molecules of propanol

Answer:

The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... These areas are usually close to oceans or large bodies of water that allow more water to evaporate and form clouds.

Answer:

D. Volume

Explanation:

Properties mentioned in the question;

colour = gray

Nonmetallic

Density = 3.8 g/mL

Volume = 48.3 mL

Of the mentioned, which is extensive ?

Extensive properties are those properties that are proportional to the amount of substance present.

The correct option is D. Volume. The other properties do not change with increasing or decreasing amount of the mineral

Answer:

151.1J

Explanation:

Given parameters:

Mass of iron  = 6.21g

Initial temperature of iron  = 25°C

Final temperature of iron  = 79.8°C

Unknown:

Amount of heat = ?

Solution:

The amount of heat require to cause this temperature can be determined using the expression below;

    H  = m c (T₂ - T₁)

H is the amount of heat

m is the mass

c is the specific heat capacity

T is the temperature

    Specific heat capacity of iron 0.444J/g°C

Insert the parameters and solve;

     H  = 6.21 x 0.444 x (79.8 - 25)

     H   = 151.1J

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.

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

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

Answer:

the number of molecules in 7g nitrogen

Ans) 7 gram of Nitrogen contains 1.5×10^23 molecules =1.5e+23

1, 3, 1, 3

Explanation:

Ga - one on both sides

F - three on both sides

CN - three on both sides

K - three on both sides

But remember that CN was being multiplied by 3 on the right side already, meaning GA(CN)3 didn't mean a coefficient.

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.

Answer:

Rutherfords

Explanation:

The model of the atom supported by Bohr's hydrogen experiment is the Rutherford's model of the atom.

Rutherford through his experiment on gold foil suggested the atomic model of the atom. The model posits that an atom has a small positively charged center(nucleus) where nearly all the mass is concentrated.

The electron configuration for the electrons as listed are:

a) 1s² 2s² 2p⁵ = 9X

b) 1s² 2s² 2p⁶ 3s²  3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d⁸ = 46 X

c) 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s² 5f¹⁴

Using the quantum numbers of the identified electrons to derive the electron configuration ( the representation of the distribution of electrons in the orbit of  an atom ) electron configuration of electrons can be calculated using the formula :2n².

where n = orbit number and the various energy levels are represented as 1,2,3,4... while shells of the an atom is written as K,L,M,N

hence the electron configuration of the electrons identified by the quantum numbers are as written above.
