3. Is this exercise an analog for physical or chemical weathering? Explain your reasoning.
4. Using your observations of the chalk in different solutions, explain how a limestone cave forms.

Answers

Answer:

Limestone caves are formed when acid rain occurs.

Explanation:

When chalk pieces which is made of calcium carbonate react with acetic acid, it produces carbon dioxide, calcium acetate, and water. When calcium carbonate react with Carbonated Water produces calcium bicarbonate. Limestone cave forms when the dissolution of limestone occur when rainwater which is acidic due to the addition of carbondioxide in the air react with limestone. This dissolution removes the lime from the rock and caves are formed.

The chalk has been made up of calcium carbonate. The reaction of calcium carbonate with different solutions results in the formation of varying products.

The reaction of chalk with acetic acid results in the formation of Calcium acetate, with the production of carbon dioxide and water.

The reaction of chalk with carbonated water results in the formation of calcium bicarbonate.

The limestone caves has been formed by the dissociation of limestone with reaction of acid, forming carbon dioxide.

The formation has takes place in the acidic solution, and carbon-dioxide thus the resultant can be due to the acid rain.

Explain why CaCl2 is likely to have properties similar to those of CaBr2

Answers

Answer:

Because both compounds (CaCl2 and CaBr2) contain elements (bromine and chlorine) from the same group (group 7)

Explanation:

Elements are organized into groups on the periodic table based on the number of valence electrons contained in their outermost shell. These elements in the same group i.e. same number of valence electrons, will behave in a similar manner chemically.

CaCl2 and CaBr2 are two compounds that contains elements (Chlorine and Bromine) from the same group, which is group 7. Elements in group 7 are called HALOGENS and have 7 valence electrons in their outermost shell.

Bromine (Br) and Chorine (Cl) are responsible for the similarity in the properties of CaCl2 and CaBr2 because the Chlorine and Bromine contained in them will cause them to react similarly and behave similarly in the presence of other compounds.

Which ONE of the following compounds is least soluble in water?
A) CH3CH2CH2NH2
B) CH3CH2CH2F
C) CH3CH(OH)CH3
D) CH3CH2COOH E) CH3CH2NHCH3

Answers

The one compound among the given options that is least soluble in water is;

Option B; CH₃CH₂CH₂F

       We know in chemistry that hydrogen bonding affects solubility in that the presence of hydrogen bonding between the molecules of a substance show us that such molecules are polar. This therefore means that the molecules will be soluble in a polar solvent such as water.

      Looking at the options, all of them form hydrogen bonds except for Option B which has Fluorine (F) alone not directly bonded to hydrogen. Instead the fluorine will be bonded to a carbon atom which means it is not going to be easily soluble in water.

     In conclusion, the one compound that would be the least soluble in water is CH3CH2CH2F.

Read more at; https://brainly.in/question/1201868

The compound that is the least soluble in water is CH₃CH₂COOH, which is also known as ethanoic acid or acetic acid. Therefore, option D is correct.

Ethanoic acid is a weak acid that partially ionizes in water, releasing hydrogen ions (H+) and acetate ions. However, it does not fully dissociate into ions and remains mostly in the molecular form.

1-propanamine can form hydrogen bonds with water through the amine functional group, enhancing its solubility.

1-fluoropropane has a polar C-F bond and can also experience dipole-dipole interactions with water, making it more soluble.

2-propanol, or isopropyl alcohol, is capable of hydrogen bonding with water due to the presence of the hydroxyl group, increasing its solubility.

Dimethylamine can form hydrogen bonds with water through the amine functional group, resulting in higher solubility.

What is the use of density in the calculation of percentage by mass?​

Answers

Answer:

First, the direct method requires recording the total mass of solution, and then evaporating off the solvent. The solid left behind is the solute, which is then weighed and used to calculate mass percent. Density can also be used to determine the mass percent of an unknown concentration.

If the density of the crushed bread is different from the density of the uncrushed bread, tell which bread has the higher density. Explain how you know.

Answers

Answer:

No. It is more dense than the uncrushed bread.

Explanation:

The mass is the same, however the volume has been decreased on the crushed side, forcing more matter into one space, which increases the density.

The loaf of bread was crushed then the density of crushed bread and uncrushed bread is same.  

What is density?

Density is defined as a measurement of how tightly the material is packed together.

It can also be defined as mass of a unit volume of a material substance.

Density can be expressed as

Density = mass / volume

The density depends on mass and volume and mass and volume of crushed and uncrushed bread is same only surface area changes with structural deformation.

Thus, the loaf of bread was crushed then the density of crushed bread and uncrushed bread is same.

the number of electrons in n=1 and n=2 shells of aluminum are

Hello

In this case, since the atomic number of aluminum is 13, its electron configuration is:

[tex]Al^{13}: 1s^2,2s^2,2p^6,3s^2,3p^1[/tex]

In such a way, we can see that the level n=1 is filled with two electrons since the subshell s is able to hold two electrons and the level n=2 is also filled but with eight electrons as s holds two whereas p holds 6. Moreover, n=3 is holding three electrons.

35-40. I do not know.

41. a bee hovering around a bee hive

42. the number of valence electrons in atoms of the element

Explanation:

21. Metals are ductile and malleable (conveniently also characteristics for chewing gum). They are stretchy and squishy. Brittle is the opposite of stretchy and squishy, and is a characteristic of non-metals.

22. On the periodic table, elements higher up are safer to use in labs. They are safer because they are less likely to react with other substances. Therefore the tendency to react with other substances increases from top to bottom within the group.

23. "Noble gases stable" (periodic table song by ASAP Science). Neon is a noble gas, therefore it is stable. When elements have only one electron to gain or lose, they are very reactive or least stable.

24. The formation of an ionic bond (metal + non-metal) is caused by the giving and receiving of electrons. Neutrons and protons do not transfer. Electrons are shared in covalent/molecular bonds (between non-metals).

25. A polar covalent bond occurs between non-metals, therefore they share electrons (ionic bonds transfer electrons). Non-metals become anions (whereas metals become cations). Polar bonds have unequal sharing and nonpolar bonds have equal sharing.

26. A one-to-two ratio of  beryllium ions to chloride ions means for every Be, there are two Cl. The number of atoms is represented by the ratio, and the numbers of atoms are written as subscripts after the element symbol.

27. MgCO2  reacting with HNO3  to form magnesium nitrate and carbonic acid is a double-replacement reaction. The elements in the beginning substances "switch partners" to form the products.

Carbonic acid then breaks down into water and carbon dioxide is decomposition. This occurs when the elements that make up a compound are split up.

28. In 2Cu + O2  => 2CuO + 315 kJ , the energy is on the right side. The right side is the products, or the stuff that was made. kJ is a unit to measure energy, therefore energy was made. Exothermic is the term that means energy was released.

29. Since oxygen is needed for a fire to burn, decreasing the oxygen slows the reaction rate (the reaction is burning, formally known as combustion).

30. Two things help substances dissolve: heat and stirring. Warm water is hotter than room-temperature water and ice water. This makes the salt dissolve faster.

31. A solution that contains more solute than it would normally hold is saturated. Saturated means there is a more than concentrated amount of solute in the solution. Concentrated is when there is a maximum amount of solute that will dissolve.

32. Acids do not feel slippery -- that is a characteristic of a base. To remember, bases are generally soaps and soaps are slippery. Acids taste sour  and bases taste bitter. Both acids and bases change the color of an indicator .

33. A base produces hydroxide ions, represented by OH. The OH is usually at the end of the chemical formula. Acids produce hydrogen ions, generally written at the front of the chemical formula.

34. Adding a little bit of acid to a buffer will cause the pH of the solution to stay about the same, probably increase a little. Buffer solutions are meant to make the pH "buffer". To remember, DVDs used to buffer. It's the same thing as "lag" for phones.

35-40: I'm sorry, I have no answer.

41. Electrons orbit like the plants revolve around the sun. Electrons revolve around a nucleus. A bee hovering around a bee hive  is probably flying around it in circles.

42. The tendency of an element to react is closely related to the number of valence electrons in atoms of the element.  If the valency is 8, the electron shell is full. The element is stable, opposite to reactive -- this applies to all noble gases (group 8A on the periodic table). If the valency is 1 or 7, the element is very close to being stable but not, the "desire" is so great and makes the element very reactive.

the answer is water ! there are always the same concentration of hydrogen ions and hydroxide ions, meaning it is neutral.
