Answer:
The compound which will precipitate first will be AgI with 
Explanation:
In order to precipitate a salt solution the ionic product of salt must exceed the solubility product.
Given:
Ksp of AgI = 
Ksp of PbI2= 
As Ksp of AgI is very low it will precipitate faster than lead iodide.
Now, higher the concentration of AgI solution taken faster its precipitation.
In the given choice the highest concentration solution of AgI is 
The quantity pH stands for the negative logarithm of the H⁺ ions concentration in a solution. In equation form, pH = -log[H⁺], where [H⁺] is the concentration of hydrogen ion in molarity or moles/liter. Using this definition, the pH of the following substances are:
Oven Cleaner: pH =-log(10⁻¹³ M) = 13
Water: pH = -log(<span>0.0000007 M) = 6.15
Blood: pH = -log(</span><span>0.00000004 M) = 7.40
Vinegar: pH = -log(</span><span> 0.0063 M) = 2.2
The measure of the pH is important when it comes to reactions because pH is a strong factor. The net charge of a substance is a result of its pH. This charge is the basis of the degree of intermolecular forces like electrostatic attraction due to difference of charges by the substance and its substrate.</span>
Answer: D. Mutation in coding sequences are more likely to be deleterious to the organism than mutations in noncoding sequences.
Explanation: It was not likely to be that the coding sequences are replicated more often. The only possible explanation is that the mutations in coding is more likely to be deleterious to the organism than mutations because it is in a non coding sequence.
Answer:
- Adenine
- Guanine
- Thymine
- Cytosine
Explanation:
The nitrogen bases that form DNA are derivatives of pyrimidine and purine, both organic molecules with a heterocyclic ring.
In RNA, thymine is replaced by Uracil.
