Answer 1

Answer:

The student selected the correct tile for the problem and doesn't need to flip the tile or add another tile. The problem is ready to be solved using the chosen tile. selected the correct tile for the problem and doesn't need to flip the tile or add another tile. The problem is ready to be solved using the chosen tile.

The correct answer is option D.

The student seems to be using a tile with the following information: "1.293 metric ton + 1000 kilograms/1 metric ton" to convert the mass of the container from metric tons to grams. Given that 1 metric ton is equivalent to 1000 kilograms, this tile can be used to perform the conversion. The problem statement provides the mass of the container as 1.293 metric tons, and the student wants to find the mass in grams.

A. The student chose the wrong tile to solve the problem.

This option is not correct. The tile selected by the student is appropriate for the given problem since it allows for the conversion of metric tons to kilograms, which is a necessary step to eventually convert to grams.

B. The student chose the correct tile but needs to flip the tile to make the units cancel.

This is not the case. The tile is already set up to correctly convert from metric tons to kilograms, and subsequently to grams. There is no need to flip the tile; it is correctly oriented for the given problem.

C. The student chose the correct tile but needs to add a second tile to solve the problem.

This is not necessary either. The single tile provided by the student allows for the complete conversion from metric tons to grams.

D. There is nothing wrong. The problem is ready to be solved.

This is the correct choice. The student's tile choice is appropriate, and no additional tile is required. They can proceed to solve the problem by multiplying the given mass of the container (1.293 metric tons) by the conversion factor on the tile (1000 kilograms/1 metric ton) to obtain the mass of the container in grams.

Therefore , from the given options the correct one is D.

Explanation:

the mass of empty cylinder is 20 gram its mass when its filled completely with water is 30 gram and its mass when its filled completely with unknown liquid is 27 gram find the density of, the unknown liquid

Answers

Answer:

≈ 0.70 g/cm³ (answer rounded up to 2 decimal places)

Explanation:

The mass of empty cylinder is 20g

The mass of water filling the cylinder = 30g - 20g = 10g

The mass of unknown liquid filling the cylinder = 27g - 20g = 7g

Density of water = 997 kg/m³

Converting this density to g/cm³ we get;

1kg = 1000g , 1m³ = 1000000cm³

So density = $(997000)/(1000000)$ g/cm³ = 0.997 g/cm³

So the volume of water occupied by 10g is;

10 × 0.997 = 9.97 cm³

This volume is also occupied by 7g of the unknown liquid.

Density = mass/volume

Density of the unknown liquid = 7g ÷ 9.97cm³ = 0.702106319 g/cm³ ≈ 0.70 g/cm³ (answer rounded up to 2 decimal places)

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.

Why would you add boiling chips/stones to a solution that is to be refluxed? when should you add them?

Answers

Chip stones should be added to a solution that is to be refluxed as they act as nucleation sites for formation of solvent bubbles.

This should be added when the temperature of the liquid is still low.

What are Boiling Chips?

These are usually added to a solution as they contain trappedair which

helps in the reflux process.

The high surface area ensures it acts as nucleation sites and the best time

to dd is when the temperature of the solution is still low for best results.
