Choose the stronger acid in each of the following pairs:H₂Se or H₃As

Chemistry

H₃As is stronger acid than H₂Se.

The H-A bond strength typically determines the size of the "As" atom in an acid; the smaller the "As" atom, the stronger the H-A bond. In the Periodic Table, the atoms get bigger and the bonds get weaker as you advance down a row, strengthening the acids.

<h3>What is acid?</h3>

Any molecule or ion that may donate a proton—a Brnsted-Lowry acid—or establish a covalent bond with a pair of electrons—a Lewis acid—is regarded as an acid. The first class of acids are the Brnsted-Lowry acids, often known as proton donors.

The compound is referred to chemically as lysergic acid diethylamide, or LSD as it is more commonly known. Using it may lead you to have a distorted perception of reality and objects because it has a potent hallucinogenic effect. LSD has an effect known as tripping.

Aqueous solutions of acids with a pH lower than 8 are frequently referred to as "acids," even though the term "acid" technically only refers to the solute.

Which of the halide ions (f−, cl−, br−, and i−) is the most stable base? which is the least stable base?
Nezavi [6.7K]
You should take note that the question is about stability. A compound is stable if it does not easily react with other elements. Hence, its reactivity must be low. As you move down the group, reactivity decreases. So, the halide at the very bottom is the least reactive. It would then be logical that the most stable conjugate base is I⁻ and the least stable conjugate base is the most reactive which is F⁻.

Why is it better to use the metric system, rather than the English system, in scientific measurement?
frez [133]
The metric system is based on powers of 10 so it is much easier to convert units, often just by moving the decimal point.

An object has a mass of 45.0 g and a volume of 4.0 ml. what is its density?
andreev551 [17]

Answer:

The answer is

<h2>11.25 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

mass = 45 g

volume = 4 mL

Substitute the values into the above formula and solve for the density

We have

Density =  \frac{45}{4}

We have the final answer as

<h3>11.25 g/mL</h3>

Hope this helps you

The periodic table is based on an element's
grin007 [14]
Well, TECHNICALLY, the periodic table is "based" upon a whole myriad of characteristics. But if you're talking about the consecutive arrangement of elements...it would be B, the atomic number.
