If 10L of O2 at 273K and 1 atm is compressed to a pressure of 7 atm at 250K, what is the new volume? *Please pay attention that it says "7 atm" and not "7L"!!!*

Answers

The new volume of the gas, given the data is 1.3 L

Data obtained from the questiom Initial volume (V₁) = 10 LInitial pressure (P₁) = 1 atmInitial temperature (T₁) = 273 KNew pressure (P₂) = 7 atmNew temperature (T₂) = 250 KNew Volume (V₂) =?

How to determine the new volume

The new volume of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

(1 × 10) / 273 = (7 × V₂) / 250

Cross multiply

273 × 7 × V₂ = 10 × 250

Divide both sides by 273 × 7

V₂ = (10 × 250) / (273 × 7)

V₂ = 1.3 L

NH4+H2O →NH3+H3O

Which one is acting weaker base?

Answers

Answer:

NH3

Explanation:

In solution, they are in equilibrium. NH4+ acts as a bronsted Lowry acid and donates an H to become NH3, and NH3 acts as a bronsted lowry base and accepts an H. In this pair, NH3 is a weak base, which gets its basic character due to the presence of lone pair of nitrogen and its ability to donate it.

What volume (in liters, at 703 k and 2.04 atm) of chlorine gas is required to react with 3.39 g of p?

Answers

The volume of chlorine required is 7.71 L.

The reaction between phosphorus and chlorine is:

2P + 5Cl₂→ 5PCl₅

Therefore, 2  moles of P requires 5 moles of chlorine to react with it.

Given mass of P =3.39 g

Molar mass of P=30.97 g/mol

No. of moles of P = given mass/ molar mass = 3.39 / 30.97 = 0.109 moles

2  moles of P requires 5 moles of chlorine

0.109  moles of P will require 0.109 x 5/2 = 0.2725 moles of chlorine

According to ideal gas equation

PV=nRT

2.04 x V = 0.2725 x 0.0821 x 703

V = 0.2725 x 0.0821 x 703 / 2.04

A chemist measured the amount of magnesium oxide produced during an experiment. She finds that 999. g of magnesium oxide is produced. Calculate the
number of moles of magnesium oxide produced.
Round your answer to 3 significant digits.

Answers

Answer:

24.8 moles MgO

Explanation:

To find the number of moles produced, you need to multiply the mass (999 grams) by the molar mass of magnesium oxide. The molar mass is made up of the atomic weights of each element times their quantities in the molecule.

Molar Mass (MgO): 24.305 g/mol + 15.998 g/mol

Molar Mass (MgO): 40.303 g/mol

 999 g MgO              1 mole

What is Chemical Bonding?
Explain please.​

Answers

Answer:

Chemical bonds are how atoms, and even molecules join together.

Explanation:

There are two main types of primary chemical bonds. While secondary links relate to molecules, primary ties are atom to atom. This answer explains basic primary bonds only.

One must comprehend what a valence shell is before I proceed. The outer electron orbital of an atom is known as the valence shell. Most of the time (except from hydrogen), atoms desire to have 8 electrons in their valence shell, thus they form bonds with other atoms to accomplish this.

All bonds result in a new chemically different molecule. Now, the two types are:

Covalent: When two atoms combine their electrons to fill their valence shells. The atoms are joined together by this "sharing."Ionic: When one atom transfers an electron to another atom in order to fulfill the valence electron requirement. Because electrons have a negative charge, the atom that produced them gains a positive charge as a result of losing its negative charge. The atom that received the electron therefore acquires a negative charge. Because opposing charges attract, it seems sense that the charged atoms bind as a result.

Answers

Answer:

The air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down.

Explanation:

As molecules heat they begin to move faster. The heat from the metal plate will make the molecules at room temperature move faster. And the room temperature makes the hot place cool, making the hot plate molecules slow down.

A pressure cooker is a covered pot sealed everywhere except for a small circular opening at the top. A small weight placed over this opening determines the pressure at which steam is released from the pot. Suppose that the radius of the opening is 0.450 mm and the weight is 0.848 N. Find the maximum pressure inside the pot.

Answers

Answer:

1.02 N/mm2

Explanation:

We can see that the pressure is applied on the small weight that covers the opening.

The area of the circular opening is π(0.512 mm)

= 0.824 mm2

Pressure = Pressure = Force / Area

=  (0.847 N) / (0.824 mm2)

= 1.02 N/mm2

Sixty-three grams of copper reacted with 32 grams of sulfur. this chemical reaction produced the compound copper sulfide. what was the mass of this compound?

The mass of, [tex]Cu_2S[/tex], compound formed is 77.9g

62 grams of copper reacted with 32grams of sulfur to form copper sulfide.

[tex]Cu + S_2 \rightarrow CuS_2[/tex]

stoichiometry of Cu to S is 2:1

We need to find the limiting reactant

Molar mass of copper = 63.5 g/mol

Molar mass of Sulfur = 32 g/mol

Number of moles of Copper =  [tex]\dfrac{mass} {molar mass } = 0.99mole[/tex]

Number of moles of Sulfur = [tex]\dfrac{mass} {molar mass} = \dfrac{32g} {32g/mol} = 1 mole[/tex]

Since copper have lesser number of moles, therefore the limiting reagent is copper so the amount of product formed depends on amount of Cu present

stoichiometry of Copper to [tex]Cu_2S[/tex] is 2:1

0.99 mol of Copper forms = [tex]\dfrac{0.99} {2}[/tex]  = 0.49 mol of [tex]Cu_2S[/tex]

Mass of [tex]Cu_2S[/tex] produced = Number of moles  [tex]\times[/tex] Molar mass

When uranium ionizes and becomes u 238 5 , there are _____ protons, _____ neutrons, and _____ electrons.

Answers

The ionized uranium (238 [tex]U^{5+}[/tex]) has 92 protons, 146 neutrons and 87 electrons.

What is Uranium(238) called?

The U²³⁸ is a stable isotope of Uranium. It cannot sustain a chain reaction.

The atomic number for uranium is 92 and its atomic mass is 238.

How many protons, electrons and neutrons are there?

The atomic number for U²³⁸ is 92.

So, the number of protons or electrons = 92

Then, the number of neutrons = atomic mass - number of protons

⇒ 238 - 92 = 146

How many protons, electrons and neutrons are there in the ionized Uranium?

The Uranium is ionized and becomes ²³⁸U⁵⁺.

So,

The number of protons = 92

The number of electrons = 92 - 5 = 87 (Since uranium is ionized by 5+ electrons i.e., removing 5 electrons)

The number of neutrons = atomic mass - number of protons

= 238 - 92 = 146

Thus, when uranium ionizes and becomes ²³⁸U⁵⁺, there are 92 protons, 146 neutrons, and 87 electrons.

Basic

Considering the definition of pH, the pH of the solution is 10.47 and since it is higher than 7, it is a basic substance.

Definition of pH

pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:

pH= - log [H⁺]= - log [H₃O⁺]

Numerical scale of pH

The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.

pH in this case

In this case, you know [H₃O⁺]= 3.4×10⁻¹¹ M.

Replacing in the definition of pH:

pH= -log (3.4×10⁻¹¹ M)

Solving:

pH=  10.47

Finally, the pH of the solution is 10.47 and since it is higher than 7, it is a basic substance.
