Answer:

A. ✔️Substitution

B. ✔️Insertion

C. ✔️Deletion

Explanation:

In A, the type of mutation that is shown is Substitution. In B, the type of mutation shown is Insertion and in C, the type of mutation shown is Deletion.

Mutation refers to the change in the DNA sequence. This occurs in an organism. In gene mutation, the structure of DNA molecule changes and produces a different allele of a gene. While in chromosome mutation, there is the change in the structure or number of the whole chromosomes in a particular cell.

Actually, mutations can take place both in prokaryotic cell and in eukaryotic cell.

In genetics, there are: Substitution, Insertion and Deletion mutations.

Substitution mutation is an exchange of one base for another. Insertion mutation is simply addition of one or more nucleotide pairs in a DNA sequence while Deletion mutation refers to the situation in which a sequence of DNA is left out when there is DNA replication.

What is the mass in grams of ba(io3)2 can be dissolved in 500 ml of water at 25 degrees celcius?

lesya [120]

The mass of Ba(IO3)2 that can be dissolved in 500 ml of water at 25 degrees celcius is 2.82 g

<h3>What mass of Ba(IO3)2 can be dissolved in 500 ml of water at 25 degrees celcius?</h3>

The Ksp of Ba(IO3)2 = 1.57 × 10^-9

Molar mass of Ba(IO3)2 = 487 g/mol?

Dissociation of Ba(IO3)2 produces 3 moles of ions as follows:

$Ba(IO_{3})_{2} \leftrightharpoons Ba^{2+} + 2\:IO_{3}^{-}$

$Ksp = [Ba^{2+}]*[IO_{3}^{-}]^{2}$

$[Ba(IO_{3})_{2}] = \sqrt[3]{ksp} =\sqrt[3]{1.57 \times {10}^{ - 9} } \\ [Ba(IO_{3})_{2}] = 1.16 \times {10}^{-3} moldm^{-3}$

moles of Ba(IO3)2 = 1.16 × 10^-3 × 0.5 = 0.58 × 10^-3 moles

mass of Ba(IO3)2 = 0.58 × 10^-3 moles × 487 = 2.82 g

Therefore, mass Ba(IO3)2 that can be dissolved in 500 ml of water at 25 degrees celcius is 2.82 g.
