Answer:

Chlorine

Explanation:

Even though chlorine is highly electronegative, the best answer is no, and in this class we will consider chlorine not to form hydrogen bonds (even though it has the same electronegativity as oxygen). This is because chlorine is large and its lone electron is in a diffuse orbital, covering a large area, and thus do not have the high charge density to act as a strong hydrogen bond acceptor. But it does form weak hydrogen bonds in solid crystalline hydrogen chloride at very low temperatures.

How many grams of kno3 pellets must be dissolved in water in order to prepare 100 ml of a 8 m kno3?

Montano1993 [528]

In 8M of KNO3, there are x moles of KNO3 divided by (100/1000)L of water (because molarity is concentration, given by no. of moles divided by total volume in liters).

by changing the subject of formula, x = 0.1L × 8M = 0.8mol

given the no. of mol of KNO3, mass of KNO3 is given by no. of mol multipled by the relative molecular mass of KNO3.

mass = 0.8mol × 101.10g/mol (or whatever your periodic table says) = 80.88g

In which set of elements would all members be expected to have very similar chemical properties?A) O, S, SeB) S, Se, SiC) N, O,

Artist 52 [7]

Answer:

A. O, S, Se

Explanation:

If you look up Oxygen (O), Sulfur (S) and Selenium (Se) in the periodic table, you will see that these three fall under the same column. In the periodic table, elements are arranged in rows and columns. Columns are called groups. The elements that fall under the same group share similar chemical properties.

The elements given above are all in Group VIA or group 16.

What would happen to our solar system if the Sun had an even greater mass than it currently does?

motikmotik

Answer: If the Sun had an even greater mass then it currently does, it would have a larger gravitational pull and since it's heat would be closer to Earth, both by magnitude and gravity, life on Earth wouldn't be possible and life on Mars would be reality. Also, when the sun would explode, it would have a larger supernova and possibly create a white dwarf (something that only happens to red supergiant stars when they die), with a gravitational force so strong it wold have two beams of light coming out it's north and south poles (like a black hole).

I hope this helps!

Heating carvone with aqueous sulfuric acid converts it into carvacrol. The mechanism involves the following steps:

Fittoniya [83]

Answer:

See figure 1

Explanation:

In this question, we have to start with the protonation of the double bond. In carvone we have two double bonds, so, we have to decide first which one would be protonated.

The problem states that the terminal alkene is the one that would is protonated. Therefore, we have to do the protonation in the double bond at the bottom to produce the carbocation number 1. Then, a hydride shift takes place to produce the carbocation number 2. A continuation, an elimination reaction takes place to produce the conjugated diene. Then the diene is protonated at the carbonyl group and with an elimination reaction of an hydrogen in the alpha carbon we can obtain carvacol.
