Two solids of identical mass, A and B, are analyzed using identical calorimeters. Each calorimeter contains the same amount of water and is at room temperature. When the solids are heated to the same initial temperature and placed in their calorimeters, the final temperature of solid A's calorimeter is higher than that of B. What can we infer from this

Answers

Answer 1

Answer:

Specific heat of solid A is greater than specific heat of solid B.

Explanation:

In the calorimeter, as the temperature is increasing, the vibrational kinetic energy will increase and this means that additional amount of energy will be needed to increase the temperature by the same value. Therefore, we can conclude that specific heat increases as temperature increases.

Now, we are told that the final temperature of solid A's calorimeter is higher than that of B.

This means from our definition earlier, Solid A will have a higher specific heat that solid B.

Explain which intermolecular force is primarily responsible for the unusually high boiling point of H2OH2O. Compare the strengths of intermolecular forces of attraction present in a sample of liquid water to the strengths of intermolecular forces of attraction present in liquid samples of H2SH2S, H2SeH2Se, and H2TeH2Te. Justify your answer using the information presented in both tables, and complete the statements below.

Answers

Answer:

See explanation

Explanation:

Intermolecular forces are forces of attraction that exist between molecules of a substance in a particular state of matter.

The dominant intermolecular force of attraction in H2O is the hydrogen bond. The hydrogen bond exists between molecules of a substance when the substance is made of hydrogen atoms bonded to atoms of a highly electronegative element. Hence, strong hydrogen bonding accounts for the high boiling point of water.

The magnitude of hydrogen bonding between molecules depends on the electro negativity of the atoms to which hydrogen is bonded.

The more the electro negativity of the atoms to which hydrogen is bonded, the greater the magnitude of intermolecular hydrogen bonding.

Since the electro negativity of elements decrease down the group, the strength of intermolecular hydrogen bonding between the molecules decreases as follows;

H2O> H2S> H2Se> H2Te

A student measures the volume of a small irregularly- shaped stone. Which apparatus must be used? a. a measuring cylinder containing water and a ruler only. b. a measuring cylinder containing water only. c. an empty measuring cylinder and a ruler only. d. a ruler only.​

Answers

Answer:

a measuring cylinder containing water only.

Explanation:

If we want to measure the volume of an irregular object. We need a properly calibrated measuring cylinder filled with water of known volume.

The irregular object is now inserted into the measuring cylinder containing water and the change in the volume of water is noted. The volume of the irregular object is now obtained as;

New volume of water - initial volume of water.

Hence, only a measuring cylinder filled with water is required to measure the volume of a small irregularly- shaped stone.

Answers

Answer:

if you have options please include them, but I'll give you an idea.

Explanation:

The existence of ions happens when atoms lose or gain electrons.

if an atom gains an electron it will become a negative ion (because electrons are negative, and you gained more negativity.)

if an atom loses an electron it will become a positive ion (because it has lost negativity, which is the electron that we've lost).

Mother is frying fish in the kitchen. The aroma of fried fish can be smelled by Sofea who is sitting in the living room. Explain how the aroma of the fried fish reach the living room.​

Answers

Answer:

through process of diffusion

Explanation:

air particles and odours move freely in all directions and eventually spreads out thus reaching the sitting room

The process of diffusion causes the particles of the aroma of the fried fish to reach the living room.

What is diffusion?

Diffusion can be described as the net movement of anything such as molcules, or energy from a region of higher concentration to a region of lower concentration. Diffusion is generally driven by a gradient in Gibbs free energy or chemical potential.

The concept of diffusion can be used in fields such as physics, chemistry, biology, sociology, economics, and finance. The central idea of diffusion is common that a substance undergoing diffusion spreads out from a point or location at which there is a higher concentration of that substance.

A gradient can be defined as the change in the value of an amount such as concentration, pressure, or temperature with a change in another variable, distance.

A change in concentration over a distance is known as a concentration gradient, and a change in pressure over a distance is known as a pressure gradient.

The Latin word diffusion means "to spread out." Therefore, the aroma of the fried fish diffuses and reaches to lining room.

Which factors ALL increase reaction rate?


decrease temperature, stir, increase surface area, remove catalyst

none of these

increase temperature, increase surface area, add catalyst, stir

increase temperature, stir, decrease surface area, add catalyst

Answers

Answer:

increase temperature, increase surface areas, add catalyst, stir

The rate of reaction can be increased with the increase in temperature, surface area, adding catalyst and allowing stirring. Thus, option C is correct.

What is rate of reaction?

The rate of reaction is given as the rate of formation of product or the rate of disappearance of reactant in unit time.

The rate of reaction can be affected with:

Increase in temperature - It will increase the collisions between the reactants, and thereby the rate.

Increase in surface area - It results in increased interaction of the reactant molecules for the formation of product.

Catalyst - It lowers the activation energy of the reactant, and thereby increases the rate of reaction.

Stirring - It mediates the increase in the collisions and the surface area, and resulting in increased rate of reaction.

Thus, the rate of reaction can be increased with the increase in temperature, surface area, adding catalyst and allowing stirring. Thus, option C is correct.

a 20.5g sample of cleaning detergent contains 8.61g of NH40H.CALCULATE the percentage composition of nitrogen in the cleaning detergent sample​

Answers

Answer:

The mass percentage composition of nitrogen in the sample of the cleaning detergent is approximately 16.78%  

Explanation:

The given mass of the sample of the cleaning detergent, m₁ = 20.5 g

The mass of the ammonium hydroxide, NH₄OH in the detergent, m₂ = 8.61 g

The molar mass of NH₄OH = 35.04 g/mol

The molar mass of nitrogen, N = 14.01 g/mol

Therefore, the mass, m₃ of nitrogen, N, in 8.61 g of ammonium hydroxide, NH₄OH, is found as follows;

m₃ = (14.01/35.04) × 8.61 g = (402,087/118,800) g ≈ 3.44 g

The mass of nitrogen, N, in the ammonium hydroxide, NH₄OH, contained in the 20.5 g sample of the cleaning agent, m₃ ≈ 3.44 grams

The percentage composition of nitrogen in the sample of the cleaning detergent, %N is given as follows;

[tex]\% Composition = \dfrac{Mass \ of \ component}{Total \ mass \ of \ cleaning \ detergent} \times 100[/tex]

Therefore;

%N ≈ ((3.44 g)/(20.5 g)) × 100 ≈ 16.78 %

The percentage composition of nitrogen, %N ≈ 16.78%.
