A graduated cylinder contains exactly 40 mL of water. A rock was dropped into the
cylinder of water. The water level rose to 52 ml. What is the volume of the rock?

Answers

Explanation:

first of all you should know that

1 ml = 1 cm³

therefore

increase in volume after putting stone=∆volume

= 52 - 40

= 12 ml

= 12 cm^3

therefore volume of the rock= change in volume= 12cm^3

The volume of the rock dropped into a cylinder containing 40 mL of water is 12 mL.

From the question given above, the following data were obtained:

Volume of water = 40 mL

Volume of water + rock = 52 mL

Volume of rock =?

The volume of the rock can be obtained as follow:

Volume of rock = (Volume of water + rock) – (Volume of water)

Volume of rock = 52 – 40

Volume of rock = 12 mL

Thus, the volume of the rock is 12 mL.

An organic chemistry student is experimentally determining the melting point of fluorenone. The experimental melting points are listed below from a to e. Which one should he discard so that he can say his data is precise?a. 83.5 °C.
b. 85.6 °C.
c. 83.6 °C.
d. 83.4 °C.
e. 83.3 °C.

Answers

Answer:

To say his data is precise, he has to discard option b - 85.6 degrees Celsius

Explanation:

During laboratory experiments, the precision of a result data covers the sameness of the data generated or results got each time the experiment is performed.

For the results to be seen as precise, the temperatures recorded during each experiment should be the same, or really close to each other.

Judging based on that, option B does not fit in as it is quite different from the other results by about 2 degrees Celsius. It also indicates that some errors may have occurred during the experiment.

To say his data is precise, he has to discard option b - 85.6 degrees Celsius.

The other temperatures recorded are close to each other. This would now make the data precise.

If the mass of an object stays the same but its volume decreases, will the density increase or decrease?

Answers

Answer:

Increase

Explanation:

Density = Mass ÷ Volume

Let the mass be 100 for instance and the original volume to be 4.

100 ÷ 4 = 25

The new volume let it be 2.

100 ÷ 2 = 50

50 is more than 25 so the density increases

Is mowing the lawn a physical change or a chemical change?

Answers

Answer:

Physical change

Explanation:

The only change is in the shape, or length in this case, of the object. So its chemical makeup is still the same, it's still grass.

Mowing the lawn is considered a physical change. A physical change is a change in the physical properties of a substance or material without altering its chemical composition.

A physical change is a transformation that alters the physical properties of a substance, such as size, shape, or phase, without changing its chemical composition. In the case of mowing the lawn, the grass is physically cut into smaller pieces, but the individual grass blades themselves remain chemically unchanged.

When you run a lawnmower over a lawn, the sharp blades of the mower cut through the grass, trimming it to a desired height. This action changes the appearance and size of the grass, but it does not alter the identity or chemical composition of the grass. The grass blades are still composed of the same materials, such as cellulose and other organic compounds.

When you mow the lawn, you are cutting the grass blades into smaller pieces, but the grass itself remains the same chemically. The process of mowing only affects the physical appearance and size of the grass, not its fundamental composition.

Therefore, mowing the lawn is considered a physical change.

Which of the following observations NOT likely describes a chemical change? a A white solid was exposed to ultraviolet light and turned brown. b Two clear liquids were mixed together and a yellow solid formed c A solid was added to water and the mixture was stirred until the solid was no longer visible d A piece of metal was added to a liquid and bubbles formed on the surface of the metal

Answers

Answer:

The correct answer would be - c.  A solid was added to water and the mixture was stirred until the solid was no longer visible

Explanation:

Photostabalizing is the process where a solid change its color in the presence of ultraviolet light, it is a chemical change, so the first option would not be the correct answer.

when two liquid or aqueous solutions are mixed together and form a solid substance, this reaction is known as precipitation and it is a chemical reaction too.

When a solid is placed in a liquid and after stirring it makes the solid vanish is a physical change known as dissolving character.

Thus, the correct answer is option C.

Which of the following is equivalent to 3.2 mg?
a
3.2 x 10-15 ug
b 3.2 x 1015 ug
С
3.2 x 10-3 ug
d
3.2 x 10'ug

Answers

Answer:

The options are not really clear, however, the answer is 3.2 × 10^3ug

Explanation:

Milligram (mg) and microgram (ug) are interconvertible measurements of mass or weight. One microgram (ug) is a millionth gram while one milligram (mg) is a thousandth gram.

Hence, one milligram is a thousandth microgram i.e. 1 mg = 1000 ug

Therefore, a measurement of 3.2mg in ug will be; 3.2 × 1000

= 3200

= 3.2 × 10^3 ug

Hence, an equivalent measurement of 3.2mg is 3.2 × 10^3ug.

If you find the mass of a sample to be 42.1 g and the actual mass is 42.0 g. your percent error would be what?

Answers

Answer:

0.24%

Explanation:

To find the percent error, first subtract the actual value by the expected value.  You can ignore the sign of the difference.

42.0 - 42.1 = -0.1 = 0.1

Divide the difference by the expected value and multiply by 100%.

0.1/42.1 = 0.0024 × 100% = 0.24%

The percent error is 0.24%.
