Answers

Answer:

0.75 M

Explanation:

Molarity = moles of solute / liters of solution

so;

Molarity = [tex]\frac{1.5 Moles}{2.0 Liters}[/tex]

According to molar concentration, the molarity of this solution is 0.75 molar.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.Substitution in formula gives, molarity= 1.5/2=0.75 M

Thus,  the molarity of this solution is 0.75 molar.

An aluminum can holds 350 mL of gas at 0 C and 1.0 atm. what is the new volume if the can is heated to 10 C and the pressure inside the can rises to 75 atm?

Answers

Answer:

Final volume of the gas is 4.837mL

Explanation:

Initial volume (V1) = 350mL = 0.35L

Initial temperature (T1) = 0°C = (0 + 273.15)k = 273.15k

Initial pressure (P1) = 1.0atm

Final volume (V2) = ?

Final temperature (T2) = 10°C = (10 + 273.15)k = 283.15K

Final pressure (P2) = 75atm

To solve this question, we'll have to use combined gas equation which is the combination of all gas law I.e Charle's laws, Boyle's law, Pressure law etc.

According to combined gas equation,

(P1 × V1) / T1 = (P2 × V2) / T2

Make V2 the subject of formula,

V2 = (P1 × V1 × T2) / (P2 × T1)

V2 = (1.0 × 0.35 × 283.15) / (75 × 273.15)

V2 = 99.1025 / 20,486.25

V2 = 0.004837L

V2 = 4.837mL

The final volume of the gas is 4.837mL

Answer:

4.84mL

Explanation:

Step 1:

Data obtained from the question. This include the following:

Initial volume (V1) = 350mL

Initial temperature (T1) = 0°C

Initial pressure (P1) = 1atm

Final temperature (T2) = 10°C

Final pressure (P2) = 75atm

Final volume (V2) =...?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This can be achieved by using the formula below:

T(K) = T (°C) + 273

Initial temperature (T1) = 0°C

Initial temperature (T1) = 0°C + 273 = 273K

Final temperature (T2) = 10°C

Final temperature (T2) = 10°C + 273 = 283K

Step 3:

Determination of the new volume.

The new volume can be obtained by using the general gas equation as follow:

P1V1/T1 = P2V2/T2

1 x 350/273 = 75 x V2/283

Cross multiply

273 x 75 x V2 = 1 x 350 x 283

Divide both side by 273 x 75

V2 = (1 x 350 x 283) / (273 x 75)

V2 = 4.84mL

Therefore, the new volume is 4.84mL

A solution has a pH of 8.4. what is the H+ concentration of the solution?

A solution has a pH of 11. What is the H+ concentration of the solution? Is the solution an acid or base?

Your father goes to the store to buy cleaner to remove such deposits from your bathtub. He has a choice between a product containing lemon juice (H+ =10^-2.5M) and one containing vinegar (H+ = 10^ -3.3M) which product would you recommend he purchase and why?

Answers

[H+]=3.98x10^-9

[H+]=10^-pH=10^-8.4

[H+]=10^-11, base

[H+]=10^-pH=10^-11

A solution with a pH of more than 7 is basic.

Lemon juice because it is more acidic

pH of lemon juice: 2.5

pH of vinegar: 3.3

Since the pH of lemon juice is lower, it is more acidic and will be more effective at removing the basic deposits.

An alkali is able to "cancel" out an acid. What is the other word for "cancelling out the acid"? * a) neutralise b) overcome c) nullify d) become acidic

Answers

Answer:

the correct answers is "neutralize"

Explanation:

When an acid is related to a base or also called an alkali and they reach a pH of 7, this acid will be neutralized or it will be canceled as the question says.

This happens so it reaches an equilibrium between both compounds, where the solution medium where these two compounds are is NEITHER ACID NOR BASIC, that is why it is called NEUTRAL medium.

Whenever you read that the pH of a solution is balanced, a neutralized acid, or a ph7 it means that the solution is NEUTRAL.

What is the total energy required to break all the bonds in 1 mol propanol,
C3H8O?

Answers

Answer:

The total energy to break all the bonds in 1 mole of 1-propanol, C₃H₈O, is 4411 kJ/mol

Explanation:

We note that propanol, C₃H₈O is also known as 1-propanol is written as follows;

CH₃CH₂CH₂OH which gives

CH₃-CH₂-CH₂-OH

Hence, the total number of bonds are;

C-H Bonds = 3 + 2 + 2 = 7

C-O Bonds = 1

O-H Bond = 1

C-C Bonds = 2

The bond energies are as follows;

C-H Bonds = 413 kJ/mol

C-O Bonds = 358 kJ/mol

O-H Bond = 468 kJ/mol

C-C Bonds = 347 kJ/mol

Energy required to break the bonds in 1-propanol is therefore;

C-H Bonds = 413 kJ/mol × 7 = 2,891 kJ/mol

C-O Bonds = 358 kJ/mol × 1 = 358 kJ/mol

O-H Bond = 468 kJ/mol × 1 = 468 kJ/mol

C-C Bonds = 347 kJ/mol × 2 = 694 kJ/mol

The total energy to break all the bonds in 1 mole of 1-propanol = 4411 kJ/mol.

Action and reaction forces are described by newtons what law of motion

Answers

According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. ... These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.

There are total three laws of newtons, first law of newtons, second law of newton and third law of newton. Therefore, action and reaction forces are described by newtons  third law of motion.

What is newton's third law?

Newton's first law is also called law of inertia. An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

Third law states that for every action there is an equal and opposite reaction. Third law is applicable in many field of physics. The third law is applicable in the running of rockets. The third law is also used by swimmers during swimming in pool.

A 10.0 g sample of an unknown liquid is vaporized at 120.0°C and 5.0 atm. The volume of the vapour is found to be 568.0 mL. The liquid is determined to be made up of 84.2% carbon and 15.8% hydrogen. What is the molecular formula for the liquid?

Answers

Answer:

C8H16

Explanation:

First thing to do here is to calculate the molar mass of the compound

Mathematically;

molar mass = mass/number of moles

we can calculate the number of moles using the ideal gas equation

Mathematically;

PV = nRT

n = PV/RT

where p is the pressure at 5 atm

V is the volume at 568 ml = 568/1000 = 0.568 L

R is the molar gas constant which is 0.0821

T is the temperature which is 120+ 273 = 393k

Inserting these values into the equation, we have

n = (5 * 0.568)/(0.0821 * 393)

n = 0.088 moles

So the molar mass = 10/0.088

= 114 g/mol

Now let’s go to the percentages

C = 84.2/12 = 7.016666666666667

H = 15.8/1 = 15.8

divide by the smallest

C = 7.016666666666667/7.016666666666667 = 1

H = 15.8/7.016666666666667 = 2 approximately

The empirical formula is CH2

So for the molecular formula, we have;

(12 + 2)n = 114

14n = 114

n = 114/14 = approximately 8

So the molecular formula of the liquid will be (CH2)n = C8H16

Given the following chemical equation at equilibrium: H2(g) + I2(g) ↔2HI(g) + heat. If the temperature is raised, in what direction will the equilibrium shift?

Answers

Answer: The reaction will shift in left or backward direction.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle. This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

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

As the given reaction is exothermic as the heat is released in the reaction. When the temperature is raised , the reaction will shift in a direction where temperature is decreasing and that is the reverse reaction which is endothermic in nature.

Thus the reaction will shift in left or backward direction.

1. If the potassium hydrogen phthalate is not completely dry, how would it affect the reported molar concentration (molarity) of the NaOH solution in Part A? Explain.

Answers

The given question is incomplete. The complete question is as follows.

Pure potassiom hydrogen phthalate is used for standardization of the sodium hydroxide solution. Suppose that the potassium hydrogen phthalate is not completely dry. Will the reported molar concentration of the sodium hydroxide solution be too high, too low, or unaffected because of the moistness of the potassium hydrogen phthalate? Explain please.

Explanation:

When potassium hydrogen phthalate is not completely dry then it means there will be some water present in it. According to this, actual potassium hydrogen phthalate is diluted because of the presence of water molecules.

Hence, 1 mole of potassium hydrogen phthalate needs 1 mole of NaOH. And, at the equivalence point according to the concept of moles:

No. of moles of potassium hydrogen phthalate = No. of moles of NaOH

Also, the titration of potassium hydrogen phthalate concentration is less because of the presence of water then the number of moles of NaOH calculated will be less.

Thus, we can conclude that the molar concentration of the sodium hydroxide solution be too low.
