Solid A at 80°C is immersed in liquid B at 60°C. Which statement correctly describes the energy changes between A and B?

Answers

We need answer options

Heat energy will be released by solid A which will then be absorbed by liquid B.

What is heat energy?

These little particles vibrate back and forth or run into each other constantly. All matter contains a type of energy known as heat (or thermal) energy, which is produced by the movement of particles.

Particle energy increases with temperature. It is possible for some of this energy to be transferred to cooler particles. For instance, in the gas state, when a fast-moving particle strikes a slower-moving particle, some of the energy from the collision is transferred to the slower-moving particle, increasing its speed.

A region of high energy will gradually spread throughout the material as a result of billions of moving particles colliding with one another until thermal equilibrium is established.

Therefore, heat energy will be released by solid A which will then be absorbed by liquid B.

A 200 milliliter sample of gas has a pressure of 1 atmosphere. If the volume of the gas is decreased to 50 milliliters at constant temperature, the new pressure of the gas will be

1) 4 atm
2) 1 atm
3) 3 atm
4) 2 atm

Answers

Answer:

Answer is - 2. ...........

At constant temperature, if the volume of the sample of gas decreases, the pressure increases to 4.0atm.

Hence, option1)4 atm is the correct answer.

What is Boyle's law?

Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.

Boyle's law is expressed as;

P₁V₁ = P₂V₂

Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.

Given the data in the question question;

Initial volume of the gas V₁ = 200mL = 0.2LInitial pressure of the gas P₁ = 1.0atmFinal volume of the gas V₂ = 50.mL = 0.05LFinal pressure of the gas P₂ = ?

We substitute our given values into the expression above to determine the new pressure.

P₁V₁ = P₂V₂

P₂ = P₁V₁ / V₂

P₂ = ( 1.0atm × 0.2L ) / 0.05L

P₂ = 0.2Latm / 0.05L

P₂ = 4atm

At constant temperature, if the volume of the sample of gas decreases, the pressure increases to 4.0atm.

Hence, option1)4 atm is the correct answer.

A weather balloon has a volume of 200.0 L at a pressure of 760 mm Hg. As it rises, the pressure decreases to 282 mm Hg.

a. Will the volume of the balloon increase or decrease? Why?

b. What is the new volume of the balloon? (Assume constant temperature)

Answers

Answer:

a. Increase

b. 539 L

Explanation:

Step 1: Given data

Initial volume (V₁): 200.0 LInitial pressure (P₁): 760 mmHgFinal volume (V₂): ?Final pressure (P₂): 282 mmHg

Step 2: Calculate the final volume of the gas

The pressure of the gas is inversely proportional to the volume. So, as the pressure decreases, the volume must increase. Assuming constant temperature and ideal behavior, we can calculate the final volume of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 760 mmHg × 200.0 L/282 mmHg = 539 L

What happens to the rate if the concentration of 1-iodopropane remains the same and the concentration of sodium hydroxide is doubled

Answers

Answer:

The rate of reaction is doubled

Explanation:

The reaction between 1-iodopropane and sodium hydroxide is an SN2 reaction. This reaction takes place by a concerted mechanism and the hydroxide ion is the nucleophile.

In an SN reaction, the reaction is second order because the rate of reaction depends both on the concentration of the alkylhalide and that of the nucleophile. Hence, when the concentration of 1-iodopropane (the alkyl halide) is held constant and the concentration of hydroxide ion (the nucleophile) is doubled, the rate of reaction is doubled since;

Rate =k [1-iodopropane] [OH^-]

1. Given the following unbalanced equation:
Al(SO3)3 + NaOH
---> Na2SO3 + Al(OH)3

If you start with 389.4 grams of Al(SO3)3 and 200 grams of NaOH ?

Identify the limiting reactant:

Identify the reactant in excess and by how much:

How many grams of Na2SO, will be produced:

If you perform the same reaction but get 212.4 grams of Na2SO3, what is
your percent yield?

Answers

Answer:

Limting reactant: NaOH

Excess reactant: Al₂(SO₃)₃ by 104.9 grams.

315 g of Na₂SO₃ are produced in the reaction

67.4 % is the percent yield.

Explanation:

Balaced equation is:

Al₂(SO₃)₃ + 6NaOH → 3Na₂SO₃ + 2Al(OH)₃

We convert the mass of each reactant to moles, to identify the limiting reactant:

389.4 g . 1mol/ 342.15g = 1.14 moles of sulfite

200 g . 1mol / 40g = 5 moles

1 mol of aluminum sulfite react to 6 moles of NaOH, according to stoichiometry.

If we have 1.14 moles of sulfite, we need (1.14 . 6)/1 = 6.82 moles

We only have 5 mol of NaOH, so this is the limiting reactant.

Then the aluminum sulfite is the excess.

6 moles of NaOH react to 1 mol of sulfite

Then, 5 moles of NaOH may react to (5 . 1)/6 = 0.83 moles.

1.14 mol - 0.83 mol = 0.31 moles remains after the reaction goes complete.

We convert to mass: 0.31 mol . 342.15g/mol = 104.9 g

Then, we work with the limiting reactant. Stoichiometry is 6:3 (2)

6 moles of NaOH can produce 3 moles of sodium sulfite

Then 5 moles will produce (5 . 3)/6 = 2.5 moles

We convert moles to mass: 2.5 mol . 126 g/mol = 315 g.

Percent yield = (Yield produced/Thoeretical yield) . 100

Percent yield = (212.4g /315g) . 100 = 67.4  %

The most common experimental technique to perform elemental analysis is combustion analysis, where a sample is burned in a large excess of oxygen and the combustion products are trapped in a variety of ways. A 99.99% pure, 0.4808 g sample containing only carbon, hydrogen, and nitrogen is subjected to combustion analysis, resulting in the formation of 0.6859 g CO2, 0.6973 g H2O, and 0.4646 g NO. What is the empirical formula of the sample

Answers

Answer:

C₂H₅N₂

Explanation:

In the combustion analysis, all NO comes from the nitrogen of the sample, that means:

Moles NO = Moles N in the sample

In the same way:

Moles CO2 = Moles C in the sample

Moles H2O = 1/2 moles H in the sample

To solve this problem we must convert the mass of each gas to moles in order to find the moles of each atom. The empirical formula is the simplest whole number ratio of atoms presents in the molecule:

Moles NO = N -Molar mass: 30g/mol

0.4646g * (1mol / 30g) = 0.01549 moles N

Moles CO2 = C -Molar mass: 44.01g/mol-

0.6859g * (1mol / 44.01g) = 0.01559 moles C

Moles H2O = 1/2moles H -Molar mass: 18.02g/mol-

0.6973g * (1mol / 18.02g) = 0.03870 moles H

The ratio of atoms is -Dividing in the low number of moles = moles N-:

C = 0.01559 / 0.01549 = 1

N = 0.01549 / 0.01549 = 1

H = 0.03870 / 0.01549 = 2.5

Twice this ratio of atoms -Because empirical formula must be given only with whole numbers:

C = 2

N = 2

H = 5

The empirical formula is:

Can you help with question 8

Answers

Answer:

pH = 9.4

Explanation:

With the given molarity of OH⁻ species we can calculate the pOH of the solution:

pOH = -log[OH⁻]

pOH = 2.6

Now we can use the pOH to calculate the pH of the solution, with the following formula:

pH = 14 - pOH

pH = 14 - 2.6

pH = 9.4

So a solution containing a OH⁻ concentration of 0.0025 M has a pH of 9.4.

What is the temperature of an 11.2-L sample of carbon monoxide, CO, at 744 torr if it occupies 13.3 L at 55 °C and 744 torr? 3C The pressure is not changing, so it looks like a case where charles’ law can be use.

Answers

Answer: The tempearture of 11.2 L of CO is [tex]3.0^0C[/tex].

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where,

[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.

are the final volume and temperature of the gas.

We are given:

[tex]V_1=11.2L\\T_1=?\\V_2=13.3L\\T_2=55^0C=(55+273)K=328K[/tex]

Putting values in above equation, we get:

[tex]\frac{11.2L}{T_1}=\frac{13.3L}{328K}\\\\T_1=276K=(276-273)^0C=3.0^0C[/tex]

Thus the tempearture of 11.2 L of CO is [tex]3.0^0C[/tex], pressure remaining constant.

A sample of unknown pressure occupies 0.776L at a temperature of 298K. The sample of gas is then tested under known

A. 27.43 kPa

B. 38.62 kPa

C. 58.73 kPa

D. 84.11 kPa

Answers

Answer:

27.43 kPa (Option A)

Explanation:

We can solve this by the use of the Ideal Gases Law.

P . V = n . R . T

As n and R are constant, we avoid them from the equation so:

P₁ . V₁ / T₁ = P₂ . V₂ / T₂

P₁ . 0776L / 298K = 32.6 kPa . 0.664L / 303K

P₁ . 0776L / 298K = 0.0714 kPa .L/K

P₁ . 0776L = 0.0714 kPa .L/K  . 298K

P₁ = 21.289 kPa.L / 0.776L

P₁ = 27.43 kPa

Explain how medicines that you can get without a prescription be more dangerous than those with a prescription. Use evidence from the text to support your answer. what is the answer to this? Read the excerpt from How Hurricanes Form.Hurricanes are often compared to engines. Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing. The system rotates faster and faster until the eye of the storm forms in the center area. Ironically, the eye of the storm is the calmest part, and it has very low air pressure.
