Answer:

Compare the solubility of silver iodide in each of the following aqueous solutions:

a. 0.10 M AgCH3COO

b. 0.10 M NaI

c. 0.10 M KCH3COO

d. 0.10 M NH4NO3

1. More soluble than in pure water.

2. Similar solubility as in pure water.

3. Less soluble than in pure water.

Explanation:

This can be explained based on common ion effect.

According to common ion effect the solubility of a sparingly soluble salt decreases further in a solution which has a common ion to it.

The solubility of AgI(s) silver iodide in water is shown below:

$AgI(s) Ag^{+}(aq)+I^{-}(aq)\\$

a. a. 0.10 M AgCH3COO has a common ion Ag+ with AgI.

So, AgI is less soluble than in pure water in this solution.

b. 0.10 M NaI has a common ion I- with AgI.

So, AgI is less soluble than in pure water in this solution.

c. 0.10 M KCH3COO:

This solution has no common ion with AgI.

So, AgI has similar solubility as in pure water.

d. 0.10 M NH4NO3:

In this solution, AgI can be more soluble than in pure water.

Discuss electrochemical principle about rusting of iron

Levart [38]

Answer:

The electrochemical phenomenon of rusting of iron can be described as : At Anode: Fe (s) undergoes oxidation to releases electrons. Electrons released at anode move to another metal and reduce oxygen in presence of H+. It is available from H2CO3 formed from the dissolution of CO2 from air into water.

Identify one disadvantage to each of the following models of electron configuration

8_murik_8 [283]

Answer:

The disadvantages or the limitations are as follows:

Dot structures: based on an empirical trend “atoms like octets”, not a rigorous description of the true nature of electrons

Arrow and line diagrams: Does not say much of the possible properties of the molecule.

Written electron configurations: no 3D representation of the molecule or the atom

nasty-shy [4]

Answer:

<em>D) raises blood glucose levels. </em>

Explanation:

Glucagon is a small polypeptide synthesized by cells. This 29 amino acid peptide hormone is synthesized by pancreas alpha cells and has a molecular weight of 3485 dalton

It has an opposite effect to insulin by increasing blood glucose levels since it increases phosphorylase activity through cyclic AMP, after binding to glucagon receptors coupled to protein G on hepatocytes.

It is a stress hormone. Stimulates catabolic processes and inhibits anabolic processes.

The correct answer is D. raises blood glucose levels.
