Answer:

5.98 × 10^22 particles

Explanation:

To get the number of particles (nA) in a substance, we multiply the number of moles of the substance by Avogadro's number (6.02 × 10^23)

The mass of Al2(SO4)3 given in this question is as follows: 34grams.

To convert this mass value to moles, we use;

Mole = mass/molar mass

Molar Mass of Al2(SO4)3 = 27(2) + {(32 + 16(4) }3

= 54 + (32 + 64)3

= 54 + 288

= 342g/mol

mole (n) = 34/342

n = 0.0994mol

number of particles (nA) of Al2(SO4)3 = 0.0994 × 6.02 × 10^23

= 0.598 × 10^23

= 5.98 × 10^22 particles

Explanation:

La reacción entre un ácido y una base se llama neutralización. Cuando en la reacción participan un ácido fuerte y una base fuerte se obtiene una sal y agua. Si una de las especies es de naturaleza débil y la neutralización se produce en disolución acuosa también se obtiene su respectiva especie conjugada y agua.

Explanation:

Atomic mass of Sulfur = 32g

32g of Sulfur is one mole.

1g of Sulfur is [tex] \frac{1}{32} moles [/tex]

96.21g of Sulfur is [tex] \frac{96.21}{32} moles=> 3moles(appx) [/tex]

Answer:

[tex]\boxed {\boxed {\sf 3 \ moles \ sulfur}}[/tex]

Explanation:

To convert from grams to moles, the molar mass is used. This value is the number of grams in 1 mole of a substance and it can be found on the Periodic Table. Look for Sulfur or S.

We use this as a ratio.

[tex]\frac {32.07 \ g \ S}{1 \ mo;\l\ S }[/tex]

Multiply by the given number of grams.

[tex]96.21 \ g \ S*\frac {32.07 \ g \ S}{1 \ mo\l\ S }[/tex]

Flip the fraction so the grams of sulfur cancel out.

[tex]96.21 \ g \ S*\frac {1 \ mol \ S}{32.07 \ g \ S }[/tex]

[tex]96.21*\frac {1 \ mol \ S}{32.07 }[/tex]

[tex]\frac {96.21 \ mol \ S}{32.07 }= 3 \ mol \ S[/tex]

96.21 grams of sulfur is equal to 3 moles of sulfur.

Explanation:

siltstone

Over millions of years, silt washed into a lake formed layers of sedimentary rock. What type of rock was likely formed? A type of detrital sedimentary rock called siltstone was the likely product of this process.

Answer:

B) Oxygen atoms

Explanation:

When metals react oxygen atom then they tend to form metal oxides which are basic in nature. This is because when metal oxides are added in water then it results in the formation of metal hydroxides which are alkaline in nature

Answer:

Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires.

Answer:

true

Explanation:

Answer:

The pressure will be 4.27 atm.

Explanation:

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Where P = pressure, T = temperature, K = Constant

This law indicates that the quotient between pressure and temperature is constant.

This law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.

In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.

You want to study two different states, an initial state and a final state. You have a gas that is at a pressure P1 and a temperature T1 at the beginning of the experiment. By varying the temperature to a new value T2, then the pressure will change to P2, and the following will be fulfilled:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{4 atm}{293 K} =\frac{P2}{313 K}[/tex]

Solving:

[tex]P2= 313 K* \frac{4 atm}{293 K}[/tex]

P2= 4.27 atm

The pressure will be 4.27 atm.

Answer:

Explanation:

Solid is a hard and not able to flow; not like a liquid or gas. Having no holes; not hollow. Something that is not liquid and gas. Solid has fixed volume but not a fixed shape.

The liquid is something that flows freely; a substance that is not solid or gas.

Gas is a substance that neither liquid nor solid, e.g. air.

Plasma is an electrically neutral ionized gas in an electric discharge; distinctly different from solids and liquids and normal gases.

Therefore, the correct answer is C. solid.

Answer:

A. Liquid

Answer:

Element   atom    molar mass     Total        % composition

Na               1            23                    40             57.5 %

O                 1            16                     40              40%

H                1               1                      40              2.5 %

The given compound is NaOH.

Na : number of atom= 1

Molar mass= 23 g/mol

Total mass of NaOH = 40 g/mol

% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{23}{40}\times 100=57.5\%[/tex]

O : number of atom= 1

Molar mass= 16 g/mol

Total mass of NaOH = 40 g/mol

% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{16}{40}\times 100=40\%[/tex]

H : number of atom= 1

Molar mass= 1 g/mol

Total mass of NaOH = 40 g/mol

% composition by mass = [tex]\frac{\text {mass of atom}}{\text {Total mass}}\times 100=\frac{1}{40}\times 100=2.5\%[/tex]

Answer:

I don't know what to say sorry

Answer:

There would be [tex]20[/tex] neutrons in that atom.

Explanation:

The mass number of an atom is the sum of:

Electrons do not contribute to the mass number of an atom.

From the question:

[tex](\text{Mass Number}) = (\text{Number of protons}) + (\text{Number of neutrons})[/tex].

In this atom:

[tex]39 = 19 + (\text{Number of neutrons})[/tex].

Hence, the number of neutrons would be [tex]39 - 19 = 20[/tex].

Answer:

f

Explanation:

Answer:

it decreases

Explanation:

It is a common saying the pressure decreases with height. This means that as altitude increases, the pressure of air decreases. The higher you go above sea level, the pressure becomes lesser.

This is as a result of decrease in the amount of air above sea level and hence a decrease in the density of air as altitude increases.

Hence, with increasing altitude, pressure decreases.

Answer:

It decreases

Answer:

55.1 g Si.

Explanation:

Hello there!

In this case, for the given mole-mole relationship, it is possible to set up the following mole ratio as the moles of Si and P are the same:

1 mol Si = 1 mol P.

Next, since one mole of silicon has a mass of 28.09 g and one of phosphorous of 31.0 g, we can set up the following expression for the mass of silicon:

[tex]60.8gP*\frac{1molP}{31.0gP}*\frac{1molSi}{1molP}*\frac{28.09gSi}{1molSi}[/tex]

Therefore, the result is 55.1 grams of silicon.

Answer: The concentration of [tex]I_2[/tex] at equilibrium is 0.45 M

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_c[/tex]  

For the given chemical reaction:

[tex]H_2(g)+I_2(g)\rightarrow 2HI(g)[/tex]

The expression for [tex]K_c[/tex] is written as:

[tex]K_c=\frac{[HI]^2}{[H_2]^1[I_2]^1}[/tex]

[tex]6.0=\frac{(0.90)^2}{(0.30)^1\times (I_2)^1}[/tex]

[tex][I_2]=0.45M[/tex]  

Thus concentration of [tex]I_2[/tex] at equilibrium is 0.45 M
