This is an incomplete question, here is a complete question.

Hydrogen and iodine react to form hydrogen iodide, like this:

$H_2(g)+I_2(g)\rightarrow 2HI(g)$

Also, a chemist finds that at a certain temperature the equilibrium mixture of hydrogen, iodine, and hydrogen iodide has the following composition:

Compound Pressure at equilibrium

$H_2$ 61.8 atm

$I_2$ 46.5 atm

$HI$ 52.3 atm

Calculate the value of the equilibrium constant $K_p$ for this reaction. Round your answer to 2 significant digits.

Answer : The value of equilibrium constant $K_p$ for this reaction is, 0.952

Explanation :

The given chemical reaction :

$H_2(g)+I_2(g)\rightarrow 2HI(g)$

The expression of $K_p$ for above reaction follows:

$K_p=\frac{(P_{HI})^2}{P_{H_2}\times P_{I_2}}$

We are given:

$P_{H_2}=61.8atm$

$P_{I_2}=46.5atm$

$P_{HI}=52.3atm$

Putting values in above equation, we get:

$K_p=\frac{(52.3)^2}{61.8\times 46.5}\\\\K_p=0.952$

Therefore, the value of equilibrium constant $K_p$ for this reaction is, 0.952

Choose the weaker acid in each of the following pairs:H₂SO₃ or H₂SO₄

WINSTONCH [101]

H₂SO₃ is weaker acid than H₂SO₄.

The bonding power of an acid is typically influenced by the size of the "SO₄" atom; the smaller the "SO₄" atom, the stronger the H-A bond. The atoms get larger and the bonds get weaker as you proceed down a row in the Periodic Table, strengthening the acids.

<h3>Describe acid.</h3>

The term "acid" refers to any molecule or ion that can donate a proton (a Brnsted-Lowry acid) or establish a covalent bond with an electron pair (a Lewis acid). The first class of acids is the proton donors, also known as Brnsted-Lowry acids.

Its chemical name is lysergic acid diethylamide, or LSD as it is more often known. Because it has a potent hallucinogenic impact, using it could alter how you see the world and its objects. The effects of LSD are referred to as tripping.

The term "acid" is frequently used to denote aqueous solutions of acids with a pH lower than 8, even though the technical meaning of the term only pertains to the solute.

Is the following chemical equation balanced? MgI 2 + Br 2 MgBr 2 + I 2

kirill [66]

count the elements in eqn MgI2 + Br2 -> MgBr2 + I2

1 Mg, 2I, 2Br on the left n

1 Mg, 2I, 2Br on the right

they are equal so the eqn is balanced

Which form of asexual reproduction describes the process of a cell dividing to

stepan [7]

Answer:A

Explanation:Binary Fission, meaning ‘getting divided into half’ is a type of asexual reproduction where a single living cell grows twice its size and then splits to form two identical daughter cells, each carrying a copy of the parent cell’s genetic material. Examples of cells that use binary fission for division
