2) 0₂
1) Al

4A1+30 2AlO36.0 Mol Al Can Form 3.0 Mol Al2O3.4.0 Mol O2 Can Form 2.7 Mol Al2O3.Which Reactant Is Limiting

Answers

Answer 1

4A1+30₂ → 2Al₂O3,6.0 mol Al can form 3.0 mol Al2O3 and 4.0 mol O2 can form 2.7 mol Al2O3. Oxygen reactant is limiting. Therefore, option 2 is correct.

What is limiting reactant ?

The limiting reagent is a substance that prevents a chemical reaction from occurring completely. When a limiting reagent is used in a chemical reaction, the atoms, molecules, or ions of the other reactant that it (the limiting reagent) reacts with will either stay free or unreacted.

As you can see, O2 creates less of the final good. Therefore, the limiting reactant is O2. Keep in mind that the limiting reactant is the one that depletes before the other reactant(s) are fully reacted. As a result, 2.7 moles of Al2O3 were actually created.

Thus, option 2 is correct.

A Liquid B Gas C Solid D Plasma

Answers

Answer:

C. solid

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.

As altitude increases, what happens to air pressure the choices are it fluctuates, it increases, it decreases or it stays the same

Answers

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

An atom of a certain element has 19 protons, 19 electrons, and a mass number of 39. This element is very reactive. How many neutrons are in this atom?

Answers

Answer:

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

Explanation:

The mass number of an atom is the sum of:

the number of neutrons in this atom, andthe number of protons in this atom.

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

From the question:

Mass number of this atom: [tex]39[/tex].Number of protons in this atom: [tex]19[/tex].

[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].

You had a closed tank of air at a pressure of 4 atm and temperature of 20 degrees Celsius. When the tank and the air are heated to 40 degrees Celsius, what is the pressure if the volume remains constant?​

Answers

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:

P1= 4 atmT1= 20 C= 293 K (being 0 C= 273 K)P2= ?T2= 40 C= 313 K

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.

6) A student measures out 96.21 g of sulfur for an experiment. How many moles of Sulfur are in this
sample? (show your work!)

Answers

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.

Sulfur: 32.07 g/mol

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.

How is the chemical bonding between atoms of magnesium different from the chemical bonding within a crystal of aluminum iodide?

Answers

Answer:

See explanation

Explanation:

The bond between magnesium atoms is a metallic bond while the bond within a crystal of aluminum iodide is an ionic bond.

A metallic crystal consists of a sea of electrons that are electrostatically attracted to positive metal ions. This is the nature of the bonding between magnesium atoms in a crystal of magnesium.

In aluminum iodide, there is a transfer of electrons from aluminium to iodine which is typical of an ionic bond. Electrostatic interaction holds oppositely charged ions together in the crystal of aluminum iodide.

How many particles are in a 34 g sample of Al2(SO4)3?
please help!

Answers

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
