Why do clouds usually form high in the air rather than near the earths surface

monitta

<span>"High in the air" is a matter of opinion and perspective. And, clouds do form near the earth's surface, we just call it fog. Clouds are often seen hanging around the top of mountains as well. However, the reason clouds usually form up in the air is clouds are moisture, and the moisture evaporates and rises from the earth to where the air is cooler above the earth surface. The moisture in the air then condenses to from lots of little water droplets that form the clouds. Depending upon the time of year and how warm and mosit the air is and how high and how cold the cold air is depends upon how high and what kind of clouds form.</span>

What does the term electrically neutral mean when discussing ionic compounds?

viva [34]

If you look at ionic compound, they are formed by a metal and a nonmetal. A metal is a positive ion after losing electron(s) and a nonmetal is a negative ion after gaining electron(s). Since there are both + and -, they are now electrically neutral.

Determine which of the following elements would gain electrons when becoming ions: I. Hydrogen II. Helium III. Sulfur IV. Fluori

klio [65]

Hydrogen, iron, and gallium is the correct answer. Hence, option B is correct.

<h3>What is an electron?</h3>

An electron is a negatively charged subatomic particle.

Let us take another look at the periodic table. The periodic table is composed of metals, metalloids and nonmetals.

Metals lose electrons more easily, that is why they form cations. Metals are found on the left-hand side of the periodic table.

As we move away from the left-hand side of the periodic table, the ability to form cations decreases as metallic character decreases and elements become more nonmetallic.

The noble gas helium rarely loses electrons. Fluorine would rather accept an electron to form a negative ion.

Hence, the elements hydrogen, iron and gallium are metals hence they lose electrons more easily.

Hence, option B is correct.

Complete the mechanism for the reaction by adding the missing curved arrows, atoms, bonds, charges, and nonbonding electron pair

Keith_Richards [23]

Answer:

See explanation below

Explanation:

In picture 1 attached, we have the starting structure. In picture 2, you have the answer for this.

Basically this is an acid base reaction to promove then, a condensation of the molecule.

In the first step, the carbonile substract a H atom from the HCl. Then, by resonance the OH+, pass the charge to the carbon, which is tertiary and can be easily stabilized. Now, after this, the Chlorine substract an Hydrogen to get a double bond on the carbon with the charge, and this be stable. Now, a second molecule of benzaldehyde reacts with this, so we can have a condensation product.

See picture 2 for complete mechanism.
