Carbon forms molecular compounds with some elements from Group 16. Two of these compounds are carbon dioxide, CO2, and carbon disulfide, CS2.Carbon dioxide is a colorless, odorless gas at room temperature. At standard temperature and pressure, CO2(s) changes directly to CO2(g). Carbon disulfide is formed by a direct reaction of carbon and sulfur. At room temperature, CS2 is a colorless liquid with an offensive odor. Carbon disulfide vapors are flammable. 59 Identify one physical property and one chemical property of CS2. [1]
Cranberries and grapes may have therapeutic value. A cranberry company obtained the patent for a process to extract the oil from cranberry seeds. According to the patent, this oil can be used to treat breast cancer or to reduce its incidence. The oil can be used in drinks and foods. A grape juice company claims to have evidence that certain grapes have health benefits ranging from improving cardiovascular health to improving cognitive brain function in the elderly. These claims will be tested by the Food and Drug Administration (FDA) before the companies are allowed to market their products for “treating” ailments or “improving” health. Until then, the companies can describe that their products “help to maintain” or “support” health. Until studies support their claims, the companies cannot ascribe direct health benefits to their products.Why would the FDA perform tests when a cranberry company and a grape company have already conducted research on the same products?A. The FDA is the only organization that can test if health actually improves.B. Tests that are performed by any company which benefits financially are considered unreliable.C. The FDA tests give reliability to the results of improved health obtained by each company.D. Tests performed by the FDA follow established scientific methods, but those performed by companies do not.

Answers

The fact that when in solution C₂H₅OH conducts electricity means that it is an electrolyte so you can automatically cross out A and C (the definition of an electrolyte is a substance that will conduct electricity when in a solution).  I think the correct answer is B due to the -OH group (the - indicates a covalent bond) which allows the molecule to give up a proton (H⁺).
 I hope this helps.  Let me know if anything is unclear.

Which mineral reacts to hydrochloric acid (HCl) only when powdered?

Answers

Answer:The mineral that reacts to hydrochloric acid (HCl) only when powdered is calcite. Calcite is a carbonate mineral composed of calcium carbonate (CaCO3). When calcite is in its powdered form, it readily reacts with hydrochloric acid to produce carbon dioxide (CO2), water (H2O), and calcium chloride (CaCl2). This reaction can be described by the chemical equation:

CaCO3 (s) + 2HCl (aq) → CO2 (g) + H2O (l) + CaCl2 (aq)

The reaction occurs because the surface area of the powdered calcite is increased, allowing for a greater contact area between the mineral and the hydrochloric acid. This increased contact area facilitates a faster and more vigorous reaction compared to when the calcite is in its solid, non-powdered form.

It's important to note that not all minerals react with hydrochloric acid. Only minerals that contain carbonate ions (CO3^2-) will react with hydrochloric acid to produce carbon dioxide gas. Other common minerals that exhibit this reaction include limestone and marble, which also contain calcium carbonate.

By understanding this reaction and its characteristics, you can identify calcite and other carbonate-containing minerals by their reaction to hydrochloric acid when in powdered form.

Final answer:

Calcite is a mineral that reacts to hydrochloric acid (HCl) only when powdered. This reaction produces carbon dioxide gas.

Explanation:

The mineral that reacts to hydrochloric acid (HCl) only when powdered is calcite.

When solid calcite is exposed to hydrochloric acid, it does not undergo any noticeable reaction. However, when powdered calcite is mixed with HCl, it readily fizzes and releases carbon dioxide gas.

This reaction occurs because the acid dissolves the calcite, converting it into dissolved calcium ions and carbon dioxide gas.

Theresa invested $5,000 in an account she expects will earn 7% annually. Approximately how many years will it take for the account to double in value?

Answers

It will take 10 years for the account to double in value.

What is account?

Account is defined as a record in an accounting system that keeps tabs on the financial transactions involving a particular asset, obligation, equity, source of income, or expense. It is used to document financial transactions, totals, or balances related to assets, liabilities, income, outlays, and owner equity.

Given future value = 2 x 5,000 = $10,000

Present value = $5,000

Interest rate = 7%

n = number of periods to double in value

The value of n can be calculated as

FV = PV x ( 1 + r ) ⁿ

10,000 = 5,000 x ( 1 + 0.07 ) ⁿ

2 =  1.07 ⁿ

n = ln ( 2 ) / ln ( 1.07 )

n = 10.24

Thus, it will take 10 years for the account to double in value.

Charles's law states that A-Volume decreases as pressure decreases

C- Pressure and temperature are inversely proportional
D- Volume increases as temperature increases

Answers


A modern statement of Charles's law is:  Whenthe pressure on a sample
of a dry gas is held constant, the Kelvintemperature and the volume will be
directly related.

Choice 'D' looks like the closest one.


While I was answering this question, I discovered something very useful:

I went to the internet, and opened my favorite search engine.  (I can't tell
you the name of it on here, but it rhymes with Ploogl.)  Then I just typed
'Charles Law' into the little window, and a lot of stuff popped up and told
me everything I wanted to know about it, and a lot more.  You could try it.

Which is a substance that is made up of only one type of atom? compound element solution mixture

Answers

Element is a pure substance that is made up of only one type of atom.

An element cannot be broken down by any chemical means. However, nuclear reactions can lead to the generation of new elements.
Examples of elements include: copper, neon and iron.
Currently, there are 115 known elements in nature.

Final answer:

An element is a substance made up of only one type of atom. It is the simplest form of matter and examples include hydrogen, oxygen, gold, and silver.

Explanation:

A substance that is made up of only one type of atom is an element. Elements are the simplest form of matter that cannot be broken down into simpler substances by ordinary chemical means. Examples of elements include hydrogen, oxygen, gold, and silver, each comprising only one type of atom. On the other hand, compounds, mixtures, and solutions can be comprised of more than one type of atom, molecule, or substance.
