g If the pressure of each gas is increased at constant temperature until condensation occurs, which gas will condense at the lowest pressure

Answers

Answer 1

The question is incomplete; the complete question is;

If the pressure of each gas is increased at constant temperature until condensation occurs, which gas will condense at the lowest pressure?

A) Octane

B) Ethane

C) Butane

D) All the gases will condense at the same pressure

Answer:

Octane

Explanation:

If we study the table closely we will realize that octane has the greatest molecular mass among all the gases shown.

The greater the molecular mass, the lower the pressure required for the condensation of the gas. Hence, the lowest pressure is required for the condensation of octane at constant temperature.

Answers

Answer:

Electrons that arent electrons

Explanation:

I teach chem

Answer:

Valence electrons are the electrons found in the highest and main energy level of the atom, being these responsible for the interaction between atoms of different species or between atoms of the same species. You can quickly determine these by looking at a periodic table like this one... Which is where the roman numbers come in and show the valence electrons. (THIS TABLE IS IN SPANISH, I hope you still recognize the symbols.) :))

A deck of cards has dimensions 8.9cm x 5.72cm x 1.82 cm. What is the volume of the deck in cubic centimeters?

Answers

The volume of the deck having dimensions 8.9cm x 5.72cm x 1.82 cm is 92.65 cubic centimeters.

How to find the volume of the Cube ?

The volume of a cube is obtained by multiplying its side three times. The formula of volume of the cube can thus be given as, Volume of cube = , where s is the side length of the cube.

Given ;

Length : 8.9cmBreadth : 5.72cmHeight : 1.82 cm

Formula used  ;

Volume = Length x Breadth x Height

            = 8.9cm x 5.72cm x 1.82 cm.


             = 92.65 cm³ i.e, 92.65 cubic centimeters

Write a balanced equation for each of the acid-base reaction given below.a. Aqueous sulfuric acid with aqueous potassium hydroxide.

Answers

Answer:

H2SO4 + 2KOH => K2SO4 + 2H2O

Explanation:

The acid-base reaction is a type of chemical reaction that involves the exchange of hydrogen ions.

The acid-base reaction between aqueous sulfuric acid ( H2SO4 ) and aqueous potassium hydroxide (KOH) is a neutralization reaction that results in potassium sulfate and water.

sulfuric acid + potassium hydroxide => potassium sulfate + water

So, the balanced equation for this reaction is as follows:

                  H2SO4 + 2KOH => K2SO4 + 2H2O

Hence, the correct answer is "H2SO4 + 2KOH => K2SO4 + 2H2O".

Air masses that form over large bodies of water are moist. What process determines the amount of moisture in an air mass?

Answers

Answer:

I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.

In a certain chemical reaction, the bond energy of the products is 67 kJ and
that of the reactants is 52 kJ. Because energy is conserved, how much
potential energy does the system release or absorb?
O A. The reaction uses up 15 kJ of energy from the reaction system.
B. The reaction creates 15 kJ of energy when bonds form.
C. The reaction system absorbs 15 kJ of energy from the
surroundings.
O D. The surroundings absorb 15 kJ of potential energy.

Answers

D. The surroundings absorb 15 kJ of potential energy.

Further explanation

Chemical bonds = potential energy

ΔH reaction from bond energy is a breaking and forming reaction of the 2 reacting molecules

Can be formulated:

ΔH rxn =  ∑ the energy of the reagent bonds broken - ∑ the energy of the bonds formed by the product

The bond energy of the products is 67 kJ and reactants 52 kJ

[tex]\tt \Delta H_{rxn}=52-67=-15~kJ[/tex]

ΔH = negative ⇒The reaction is exothermic(releases heat to surrounding)
