Given that the density of water is 1.00 g/mL, the density of toluene is 0.867 g/mL, and the density of chloroform is 1.48 g/mL, what layer corresponds to what compound? ​

Answers

Answer:
Top-Toluene
Middle-Water
Bottom-Chloroform

Explication:
Chloroform is on the bottom layer because it is the densest liquid.
Toluene is on the top because it is the least dense.
Water is between the two because it’s density is between chloroform and toluene.

A student measures the mass of an object and obtains three values: 21.57 g,
22.04 g, and 21.35 g. What is the average mass of the object?

Answers

Answer:

21.65

Explanation:

The average = total divided by the number of readings

21.57

22.04

21.35

Total = 64.96

Average = 64.96 / 3 = 21.65

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%.

summerize in your own words Continental crust is much thicker than oceanic crust (averages between 20 to 25 miles thick), but is actually slightly less dense than oceanic crust. The main type of rock on continents is called granite. So if these two types of crust were to collide into each other, what do you think would happen to the oceanic crust? As a whole, notice that the crust is lighter than the mantle. It is sometimes said that the crust "floats" on the mantle like an iceberg in water and that is not too far from the truth and is called isostacy. Finally, the crust is the coldest, most rigid, and brittle layer with lots of folds and fractures.Recall that oceanic crust is denser than continental rock like granite. Thus when two tectonic plates collide, the denser oceanic crust will subduct underneath the lighter continental crust. If the subducting rock becomes stuck, vast amounts of energy builds up. But once the pressure and energy is too great, the rock will rupture creating powerful earthquakes. As the subducted material sinks further, it will begin to melt under great heat and pressure, becoming less dense as it melts, and rise up as magma to form dangerous composite volcanoes. Mountain ranges created by oceanic-to-continental convergence are the Andes mountains in South America, the Cascades in the western United States, and the Ring of Fire in the Pacific Ocean.

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.

The three chemical compounds used in the daily life are carbon dioxide (CO2), ammonia (NH3), and water (H2O).

What is a chemical symbol?

Chemical symbols are acronyms for chemical elements, functional groups, and chemical substances that are used in chemistry.

Chemical element symbols are typically composed of one or two letters from the Latin alphabet, with the first letter capitalized.

A chemical symbol, also known as an element symbol, is a letter or a combination of letters that represents a chemical element.

Because it is shorter and easier to write, the chemical symbol for an element is used when writing the chemical formula for a molecule or when writing a chemical equation.

Carbon dioxide (CO2), ammonia (NH3), and water are the three chemical compounds encountered in daily life (H2O).

Thus, these are some of the examples of chemical compounds.

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.

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.
