Bill, a lab technician, was asked to measure out sodium hydroxide (NaOH) for an experiment in a research lab. He was given a choice between a beaker, a graduated cylinder, and a buret (shown left). Bill used a graduated cylinder to measure the liquid NaOH because he says, “a graduated cylinder is the most accurate way to measure a liquid!” Do you agree or disagree with Bill? Use significant figures to justify your answer.

Answers

Answer:

He is wrong . Most accurate is Buret .

Explanation:

The number of significant figure denotes the level of accuracy of a measurement .

Beaker can measure liquid in mL upto significant figure of 2 . That means it can measure volume in terms of 10 , 20 , 30mL etc . It can not measure 25 mL

accurately . The last figure of 28 mL is read by guess in the question . So it is not an accurate measurement .

Similarly , graduated cylinder can measure liquid upto significant figure of 3 .  That means it can measure volume in terms of 11 , 22 , 33 mL etc . It can not measure 25.5  mL accurately . The last figure of 28.3  mL is read by guess in the question . So it is less  accurate measurement .

Similarly , buret  can measure liquid upto significant figure of 4 .  That means it can measure volume in terms of 11.2 , 22.3 , 33.5 mL etc . It can not measure 25.53  mL accurately . The last figure of 28.32  mL is read by guess in the question . So it is most accurate among all the three instrument because it can measure accurately mL upto one tenth of it .

A paper clip released gently into the liquid settles at the bottom of the cylinder. What best compares the densities of the substances?

The clip is denser than the three liquids, and water is denser than oil.
Oil is denser than water but less dense than the clip.
Corn starch is denser than the other liquids and the clip.
Oil is denser than the other liquids, and all liquids are denser than the clip.​

Answers

Answer:

C.

Explanation:

Objects and liquids float on liquids of a higher density and sink through liquids of lower density. the water and corn starch sank under the oil as well so that means they are denser. The paper clip sank through all three liquids also. Hence, the answer would be the clip is denser than the three liquids, and water is denser than oil.

Answers

Answer:

The salt is Zn(NO3)2

When the residue is allowed to cool, its colour changes from yellow to white

The equation of the reaction is; 2Zn(NO3)2(s) --->2ZnO(s) + 4NO2(g) + O2(g)

Explanation:

Decomposition of Zn(NO3)2 is one of the routes by which ZnO is obtained. ZnO is a white insoluble powder which has a yellow colour when hot and a white colour when cold. It is an amphoteric substance used as a white pigment in paints and as a filler for rubber.

In a very pure form, it is used in cosmetic powders and creams as well as in medicinal ointments and lotions.

Also recall that NO2 is a brown gas and oxygen gas rekindles a glowing splint.

Which of the following correctly describes a mixture? (4 points)
The particles are chemically bondeg together, and they retain their individual physical and chemical pro
The particles are not chemically bonded, and they can only combine in certain set ratios.
The particles do not retain their individual chemical properties, and they can only be separated by chemi
The particles have no set ratio for how to combine, and they can be separated by physical means.

Answers

The answer is (D) - The Particles gave no set ratio for how to combine, and they can be separated by physical means.

Mixtures can be separated through means or filtration, evaporation, and sublimation. No chemical process or chemical reaction/bonding takes place. Thus, which is why It can be separated by physical means because it’s still technically in it’s own individual elements.

The statement the particles have no set ratio for how to combine, and they can be separated by physical means describes a mixture.

What is mixture?A mixture is made when two or more substances are combined, but they are not combined chemically. The components of a mixture can be easily separated.  The components each keep their original properties. The proportion of the components are variables.

Physical means like filtration, evaporation, and sublimation can all be used to separate mixtures. There is no chemical reaction that takes place. As a result, it can be physically detached because it is still theoretically divided into its constituent parts.

Hence, we can conclude that option D is the answer.

You buy several bags of balloons. On the package, it says that each bag has 100 balloons. He opens the bags and only one of them has 100 balloons inside; the other bags either have too many or too few. How would you describe this sample of bags?

Answers

Answer:

Accurate but not precise

Explanation:

The sample of balloon bags can be described as being accurate but not precise.

Recall that accuracy is the closeness of measurements to their true values while precision is the closeness of repeated measurement.

The balloon bags are accurate because it appears that the number of balloons in each bag is not far from the actual number of balloons that should be in them - exactly 100 in one and a few off in others. By the time the average number of balloons is calculated, it will not be far off from 100, if not exactly 100.

However, the sample bags are described as not being precise because of the inconsistency or lack of closeness in the number of balloons in each of them.

Texas Ranchers are not fond of the mesquite tree. The tree invades range land and prevents the growth of other vegetation. Bee keepers, however, prize the nectar from the blooms of the mesquite tree because it makes the sweetest honey (measured in grams of sugar/ per ounce of honey). Can the rancher and the bee keeper live in the same community? Design an experiment to test various flower blooms to produce the same honey as the mesquite's blooms.

Answers

Answer:

No.

Explanation:

No, the rancher and the bee keeper can't live on the same place because the rancher need a specific area where there is a lot of vegetation for their animals while the bee keeper needs a lot of trees from which the honey bees collect nectar at the time of blooming. So both need different environment for making high yield and good profit so they can't live in the same community.

33. A student finds that the mass of 25ml of an unknown liquid is 20.5g. What is the density of this substance?​

Answers

Answer:

Density, [tex]d=0.82\ g/cm^3[/tex]

Explanation:

It is given that,

Mass of an unknown liquid, m = 20.5 g

The volume of unknown liquid is 25 mL

We need to find the volume of the brass object. Mass per unit volume of an object is called its density.

We know that, 1 mL = 1 cm³

So, 25 mL = 25 cm³

[tex]d=\dfrac{m}{V}[/tex]

Putting the values, we get :

[tex]d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3[/tex]

So, the density of this substance is [tex]0.82\ g/cm^3[/tex]

Which one of the following substances would be the most soluble in C6H6 ? Group of answer choices CO2 all of these can dissolve C6H6 C10H22 S8 (sulfur) SiO2

Answers

Answer:

C10H22

Explanation:

C6H6 is the molecular formula for Benzene. Benzene is an aromatic hydrocarbon which is obtained from the destructive distillation of coal. Benzene is a colourless volatile liquid with a sweet smell. Its vapor is highly toxic and mildly carcinogenic. It is highly inflammable. Benzene is nonpolar which is insoluble in water. Since benzene is insoluble in water , it will take an insoluble compound to be soluble in benzene since "like dissolves like".

From the options given:

C10H22 which is the molecular formula for Decane would be the most soluble in C6H6. This is because Decane is an alkanes which is an aliphatic hydrocarbon and their physical properties increases with increasing molar mass ( i.e melting points, boiling points , density, polarity) etc. The first mfour member of the family are gases. non-polar liquid starts with th fifth member of the family which is pentane and from hexadecane onwards the members are solids at room temperature. Thus, decane is a non-polar hydrocarbon which is insoluble in water but soluble in benzene

What concentration of ClO3â results when 967 mL of 0.367 M AgClO3 is mixed with 667 mL of 0.643 M Mn(ClO3)2?

Answers

Answer:

0.742M is the concentration of ClO₃⁻

Explanation:

The AgClO₃ contains 1 mole of ClO₃⁻ per mole of compound, but Mn(ClO₃)₂ contains 2 moles of ClO₃⁻ per mole of compound.

The moles of AgClO₃ are:

0.967L * (0.367moles / L) = 0.355 moles AgClO₃ = 0.355 moles of ClO₃⁻

And of Mn(ClO₃)₂:

0.667L * (0.643moles / L) = 0.429 moles Mn(ClO₃) * 2 = 0.858 moles of ClO₃⁻

That means total moles of ClO₃⁻ are:

0.355 moles + 0.858 moles = 1.213 moles ClO₃⁻ that are in 0.967L + 0.667L = 1.634L.

The concentration is:

1.213 moles ClO₃⁻ / 1.634L =

0.742M is the concentration of ClO₃⁻
