What would indicate that a physical change takes place when copper is drawn into wire?

Answers

Answer 1

Answer: A physical change takes place when copper is drawn into wire when the wire can be made into smaller in diameter but longer in length tubes. This is a physical change becasue the copper is just molded into wire without any application of any substance.

7. Which of the following has to happen before the eardrum begins to vibrate with the same frequency as the source of the sound waves? A. Vibrations have to be transmitted to the fibers of the auditory nerve.
B. Impulses have to be sent to the brain through the auditory nerve.
C. The brain has to interpret the direction from which the sounds are being delivered.
D. The outer ear has to collect the sound waves and lead them to the middle ear.

Answers

The outer ear has to collect the sound waves and lead them to the middle ear and this is what has to happen before the eardrum begins to vibrate with the same frequency as the source of the sound waves. The correct option among all the options that are given in the question is the last option or option "D".

Answer : Option D) The outer ear has to collect the sound waves and lead them to the middle ear.

Explanation : Hearing is dependent on a series of complex steps that change vibrations of sound waves in the air into electrical signals. At first the vibrations of sound waves gets collected by the outer ear and from there sound waves travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. The auditory nerve then carries these signals to the brain.

Carbon forms molecular compounds with some elements from Group 16. Two of these compounds are carbon dioxide, CO2, and carbon disulfide, CS2.Carbon dioxide is a colorless, odorless gas at room temperature. At standard temperature and pressure, CO2(s) changes directly to CO2(g).

Carbon disulfide is formed by a direct reaction of carbon and sulfur. At room temperature, CS2 is a colorless liquid with an offensive odor. Carbon disulfide vapors are flammable.

59 Identify one physical property and one chemical property of CS2. [1]

Answers

Answer: Physical property of $CS_2$ is state of matter (liquid) and it is a chemical compound.

Explanation:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.

Carbon disulfide $(CS_2)$ is the compound which is formed by the chemical combination of carbon and sulfur atoms. The equation for this follows:

$C+2S\rightarrow CS_2$

The chemical property of carbon disulfide is different from that of carbon and sulfur. Thus, this is a chemical compound.

It is given, that this compound is a colorless liquid, which means that the state of this compound is liquid state.

Hence, physical property of $CS_2$ is state of matter (liquid) and it is a chemical compound.

The physical property of carbon disulfide is that at room temperature, CS2 is a colorless liquid with an offensive odor. The chemical property of carbon disulfide is that it is formed by a direct reaction of carbon and sulfur.

In a titration, 20.0 milliliters of 0.15 M HCI(aq) is exactly neutralized by 18.0 milliliters of KOH(aq).Complete the equation in your answer booklet for the neutralization reaction by writing the formula of each product.

KOH(aq) + HCl(aq)==> ________ +________

Compare the number of moles of H+(aq) ions to the number of moles of OH-(aq) ions in the titration mixture when the HCl(aq) is exactly neutralized by the KOH(aq).

Determine the concentration of the KOH(aq).

Answers

The reaction yields H2O and KCl (remember that neutralization reactions produce water and a salt).When HCl is exactly neutralized by KOH, you are left with no excess H+ or OH- from the strong acid or strong base. Also, since both the acid and base are strong, their conjugate base and conjugate acid, respectively, have negligible basicity. Therefore, the final solution is of neutral pH and there are equal amounts of H+(aq) and OH-(aq).Since the acid is monoprotic and the base releases only 1 OH- per molecule dissociated, you need not worry about dissociation constants. In this case, you find the molarity using M1V1 = M2V2. You are finding M2, so M2 = M1V1/V2 = (0.15)(20.0)/(18.0) = 0.17M (this is considering significant figures).
