An object with a mass of 1.2 g takes up a space of 2.4 mL. What is it's density?

Answers

Answer:

The answer is 0.5 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

From the question we have

[tex]density = \frac{1.2}{2.4} \\ [/tex]

We have the final answer as

0.5 g/mL.

Hope this helps you

The formula for density is almost always expressed as grams per milliliter in chemistry. To find the density of this object, simply divide the number of grams by the number of milliliters.

Therefore, we get:

1.2g / 2.4 mL = 0.5g/mL

This results in a density of 0.5g/mL!

Which element has the
greatest number of valence electrons available for bonding?
O selenium
Oboron
O calcium
O chlorine

Answers

The element Chlorine has the greatest number of valence electrons for bonding. This is because selenium has 6 valence electrons, boron has 3 valence electrons, calcium has 2 valence electrons, and chlorine has 7 valence electrons. Therefore we can see that since 7 is the greatest number chlorine has the greatest number of valence electrons.

Why are small quantities of chlorofluorocarbons so harmful to the ozone layer? a. The chlorofluorocarbons act like ultraviolet radiation causing large amount of ozone to be produced. b. The chlorine from the chlorofluorocarbons reacts with free molecules of oxygen causing a stop in ozone production. c. Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone. d. Chlorofluorocarbons absorb ultraviolet radiation, preventing the formation of ozone.

Answers

Answer:

Why are small quantities of chlorofluorocarbons so harmful to the ozone layer?  Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone.

Explanation:

The statement for small quantities of chlorofluorocarbons so harmful to the ozone layer is "Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone."

What is ozone layer?

The ozone layer is a thin layer of air in the Earth's atmosphere that absorbs nearly all of the sun's damaging UV radiation.

What is CFCs?

CFCs (chlorofluorocarbons) are harmless and nonflammable compounds made up of carbon, chlorine, and fluorine atoms.

The earth's protective ozone layer is destroyed by chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons, which shield the earth from damaging ultraviolet (UV-B) rays released by the sun. CFCs and HCFCs also warm the earth's lower atmosphere, causing global climate change.

When some substances are exposed to high UV radiation in the stratosphere, they emit chlorine or bromine. Ozone-depleting chemicals are compounds that contribute to ozone depletion (ODS). Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), carbon tetrachloride, and methyl chloroform are examples of ODS that produce chlorine. Halons and methyl bromide are two ODS that emit bromine.

Because there isn't much ozone in the atmosphere, what little there is is critical for protecting the Earth's surface from excessive UV light from the Sun. It turns out that it reacts with chlorine, which means that chlorine effectively eliminates ozone.

When the chlorine in CFCs combines with ultraviolet light, it releases chlorine, which then reacts with ozone, reducing the protection humans get from ultraviolet light, allowing more CFCs to release chlorine, and so on. Multiple ozone molecules will interact with one free chlorine atom, which is free because UV light has hit the CFC molecule. As a result, the damage it can cause is likely to be significantly more than you might imagine.

Hence the correct option is c.

Ou are subliming camphor and you note that pure camphor is condensing nicely on the cold finger. You check on the process several minutes later and you see that the amount of camphor on the cold finger has not changed appreciably since the last time you looked at it. However, there is still plenty of impure camphor left at the bottom of the flask. What do you suppose is the reason and what do you need to do.

Answers

Answer:

The reaction is endothermic

Increase temperature of the flask

Explanation:

Sublimation is a phenomenon in which a substance changes directly from solid to gas,without passing through the liquid phase.

Camphor is a sublime substance. The sublimation of camphor is an endothermic reaction. This implies that energy is absorbed in the process.

For an endothermic reaction, the equilibrium position is shifted towards the right hand side by increasing the temperature of the system. Hence, if the flask is heated, more camphor will condense within a shorter time interval.

A physical change is easier / more difficult to reverse than a chemical change.

Answers

Answer:

the answer is that a physical change is easier to reverse then a chemical change.

Explanation: In order for a physical change to take place it's easier to just undo what happened then if it was a chemical change because in order for very few chemical changes to reverse to it's original substance you would need another chemical change.

how many atoms are in CaCI2​

Answers

Answer:

4

Explanation:

bc Ca is 1 C is one L is two

CaCl₂ is an ionic compound consisting of one calcium ion and two chloride ions; a single calcium ion has a doubly positive charge while a single chloride ion has a single negative charge. So two chloride ions bonded to one calcium ion results in an electrically neutral calcium chloride compound.

In this particular case, an ion is merely an atom with a positive or negative charge. Since there are three ions that comprise CaCl₂, there are three atoms in a single unit of CaCl₂.

Do not confuse the C here for carbon and/or the I for iodine. There is no chemical element whose symbol is “L” (yet).

The IUPAC name for NO is nitric oxide. The correct option is A.

What is IUPAC naming?

The International Union of Pure and Applied Chemistry (IUPAC) is a global organization that represents chemistry as well as related sciences and technologies.

The chemical compound's identity is represented by its common and IUPAC names, which differ from one another. Every chemical compound has multiple names.

Complete the following step-by-step response: The IUPAC nomenclature is a standardized name given to organic compounds in accordance with official naming rules.

Nitric oxide, also known as NO, is a colorless gas. It is one of the most important nitrogen oxides.

Nitric oxide is a free radical, which means it has an unpaired electron, which is sometimes represented in its chemical formula by a dot.

Thus, the correct option is A.
