Correctly classify each of the following compound as highly soluble or insoluble in water. 1. NaCl 2. CH3Cl 3. CH3OH 4. KOH 5. C

Anna35 [415]

There are solubility rules for inorganic compounds in water as shown in the picture attached. For organic compounds, we use the concept of polarity.

1. NaCl: Since NaCl is a chloride and Na is not included in the list of insoluble, therefore, NaCl is highly soluble.

2. CH₃Cl: This compound is organic. Since the electonegativity between C and Cl is great, it tends to be polar. Because water is also polar, this is highly soluble.

3. CH₃OH: This is an alcohol. Alcohols with short chains of hydrocarbon are highly soluble in water because of hydrogen bonding (-OH).

4. KOH: From the table, KOH is highly soluble. In fact, this is a strong solid which readily dissociates in water.

5. C₆H₆ is the benzene ring. This is a nonpolar molecule, so you would expect this to be insoluble with water.

6. C₆H₁₄ is hexane which is a long chain of hydrocarbons. Because there is no point of hydrogen bonding, this is nonpolar, and therefore, insoluble in water.

7. KNO₃ is highly soluble because all nitrates are soluble.

8. CCl₄ is an organic compound. Individually, C-Cl bonds are polar. But because there are 4 of them, they cancel out. As a result, there is a balance of partial charges which makes it nonpolar. Thus, this is insoluble in water.

9. NaSO₄: from the table, this is highly soluble.

10. CH₃CH₂OH: Although it is composed of the nonpolar hydrocarbon chain, the OH group is much stronger such that it is highly soluble in water.

11. CH₂Cl₂: This is polar because there is an imbalance due to the C-H and C-Cl bonds. Thus, it is highly soluble in water.

12. CH₃COOH is a carboxylic acid which is even more soluble than alcohols. Thus, this is highly soluble in water.

How many grams in 3.4 moles of Neon (Ne)?

Luba_88 [7]

Answer:

60.42 grams

Explanation:

So, neon has a molar mass of 20.18 g/mol , which means that every mole of neon has a mass of 20.18 g so that means three of them is 60.42 grams

When ice is melting, the heat being added causes:

In-s [12.5K]

Explanation:

Adding heat can cause ice (a solid) to melt to form water (a liquid). 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. Even though the water's physical form changes, its molecules stay the same.

The formation of protons over neutrons (thus producing about a 7:1 ratio) was favored in the early universe because:____.

tatiyna

Because it requires more energy to create a neutron from a proton than it does to create a proton from a neutron, protons were formed more frequently than neutrons in the early universe. The correct answer is option b.

To find the answer, we need to know more about the early universe.

<h3>How the formation of proton over neutrons was favored in the early universe?</h3>

A neutron is produced with greater energy than a proton.
However, later on, some of the protons were changed into neutrons.
Contrary to some claims, the proton is a stable particle that never decays, but the neutron is unstable outside of the nucleus and decays with a half life of around 10.5 minutes.
However, very few would have had time to decay on the timeline you mention in your question.
Every matter particle should have been accompanied by an antimatter particle, and every proton, neutron, and electron, by an anti-neutron and a positron, respectively.
Where did all the antimatter go is the great mystery. There have been a few attempts to explain this, but they have failed.

Thus, we can conclude that, the correct answer is option b.
