Vinegar is an ingredient commonly used by chefs. Scientists also use it as well, although they call it acetic acid. When vinegar is in its liquid or solid (frozen) states, it has a fixed volume. But when vinegar is in its gas state, it takes up the entire volume of whatever container it is in. This is why you can smell an open bottle of vinegar the minute you walk into a kitchen, even though you cannot actually see the gas particles!

Which statement best explains why the volume of vinegar gas is changeable as opposed to the fixed volume of its solid and liquid states?

A. Gas particles are always at a higher pressure than solids and liquids.

B. Gas particles are always at a higher temperature than solids and liquids.

C. Gas particles are spaced far apart and can move freely.

D. Gas particles stay close together but can move around each other.

Answer:

She should use the crystalization technique

Explanation:

First, the copper sulfate solution should be filtered to clear any impurities.

By heating the solution of copper sulfate on a china dish, the excess water in the solution evaporates and leaves behind a saturated solution of copper sulfate.

Upon cooling this saturated copper sulfate solution, crystals of solid copper sulfate will be formed on the china dish.

In solid form, copper sulfate appears in triclinic-shaped crystals.

Answer:  

0.15 sec/min = 9 sec/hour

9*24 = 216 seconds = 3.6 minutes

Explanation:

Answer:

216 Seconds

Explanation:

If every minute is 60 seconds than 60 multiplied by .15 is 9 Seconds Lost.

If every hour is 60 minutes compared to what we know than 24 hours multiplied by 60 is 1440 minutes.

Do the same math as before: 1440 x .15 = 216 Seconds

Answer:

Removing heat causes water (a liquid) to freeze to form ice (a solid). When water changes to a solid or a gas, we say it changes to a different state of matter. ... This causes the hydrogen atoms in one water molecule to be attracted to the oxygen atom in another water molecule.

Answer:

B and C

Explanation:

A. Their particles are held together by chemical bonds.

This option is incorrect for both compounds and mixtures. It is only true for Compounds.

B. They are made up of more than one type of atom.

This is correct. Both compounds and mixtures consists of different atoms of elements.

C. They can be separated into two or more elements.

This option is correct. Compounds are broken down into elements through chemical means.

D. Their particles all have the same chemical formula.

This is wrong. Mixtures do not have a chemical formula

The first stage of the experiment is focusing only on the physical properties of acidic property.

A physical property would be any quantifiable attribute whose value describes the condition of a physical system. Changes in a system's physical attributes are able to characterize its transitions between brief states. Physical attributes are sometimes known as observables.

Physical characteristics are frequently classified as intense or extensive. An intense property is independent of the system's size or extent, as well as the amount of material in the item, whereas an extended property has an additive link. The first stage of the experiment is focusing only on the physical properties of acidic property.

Therefore, the first stage of the experiment is focusing only on the physical properties of acidic property.

Answer:

the ability to be dissolved, especially in water.

Explanation:

Answer:

We can mix two compounds and create a third that bears little resemblance to its parents. For instance, by mixing two parts of hydrogen gas with one of oxygen - liquid water is formed. We should not be misled by the fact that chlorine and chlorine dioxide share a word in common. The chemistries of the two compounds are completely different.

Chlorine and chlorine dioxide are both oxidizing agents (electron receivers). However, chlorine has the capacity to take in two electrons, whereas chlorine dioxide can absorb five. This means that mole for mole, ClO2 is 2.6 times more effective than chlorine.

If equal, if not greater importance is the fact that chlorine dioxide will not react with many organic compounds, and as a result, ClO2 does not produce environmentally dangerous chlorinated organics. For example; aromatic compounds have carbon atoms arranged in rings and they may have other atoms, such as chlorine, attached to these rings, to form a chlorinated aromatic - a highly toxic compound that persists in the environment long after it is produced.  

Chlorine dioxide's behaviour as an oxidizing agent is quite dissimilar. Like ozone, the predominant oxidation reaction mechanism for chlorine dioxide proceeds through a process known as free radical electrophilic (i.e. electron-attracting) abstraction rather than by oxidative substitution or addition (as in chlorinating agents such as chlorine or hypochlorite). This means that chlorinated organic compounds such as THMs and HAAs are not produced as a result of disinfection using chlorine dioxide

Hope this helps, have a nice day! :D

The way that the names of these compounds show that the Chlorine oxides are different is by making reference to the number of individual molecules in the compound.

The number of chlorine and oxygen molecules in each compound are used to name the compounds which ensures that they are differentiated.

ClO₂ is called "Chlorine Dioxide" which shows that there are two Oxygen atoms.

Cl₂O₃ is called "Dichlorine Trioxide" which shows that there are two Chlorine molecules and 3 Oxygen molecules.

Answer:

4.0 moles of krypton converts to 89.6L.

Explanation:

To convert moles to liters, remember that at standard temperature and pressure (STP), 1 mole is equal to 22.4 liters. Multiply your mole value - in this case, 4.0 - by the molar volume constant, 22.4L, to convert moles into liters. 4.0 x 22.4 is equal to 89.6, thus your answer is 89.6L.

We can check this by dividing 89.6 by 4.0, which will give us the molar volume constant 22.4L, proving that this answer is correct.

Answer:

The answer is the first one.

Explanation:

The lower a pH level the higher the the number hydrogen ions present in the acid's container.

ph = - log(H)

4 = - log(H)

- 4 = log(h)

10^-4 = H+

1 * 10^-4 = H +

ph = - log(H)

ph = 2

- 2 = log(H)

10^-2 = H

1*10^-2 = h

Something the power - 2 is 100 times greater than something with the power of -4

If a solid object is taken from Earth far into space, which of the following measurements of the object will change the most?

A. density

B. mass

C. volume

D. weight

option D. weight

Because the gravity of the planet/object changes, the weight of the object changes when you move it away from the earth or place it on another planet.

However, the mass of the object remains the same regardless of whether it is on Earth or outer space.
