<h3><u>Explanation; </u></h3>

Ketones are byproducts of the breakdown of fatty acids.<u> They are organic compounds with the structure R(C=O)R', where R and R' can be a variety of carbon-containing substituents.</u>
Like aldehydes ketones contain a carbonyl group that is a carbon oxygen double bond.

What will create a insoluble salt with a potassium ion

navik [9.2K]

Explanation:

1) The dissolution of the salt potassium sulfite:

K₂SO₃(aq) → 2K⁺(aq) + SO₃²⁻(aq).

Potassium has +1 charge because it lost one electron to accomplish stabile electron configuration of noble gas argon.

2) From dissolution reaction: n(K⁺) : n(SO₃²⁻) = 2 : 1.

n(K⁺) = 0.700 mol.

0.700 mol : n(SO₃²⁻) = 2 : 1.

n(SO₃²⁻) = 0.700 mol ÷ 2.

n(SO₃²⁻) = 0.350 mol; amount of sulfite anions.

elena-14-01-66 [18.8K]

Answer: precipitate

Explanation: Chemical change is a change in which the chemical composition of the atoms changes. The following changes are seen when chemical reaction takes place:

1) Release or absorption of heat

2) Formation of solid or a precipitate

$2AgNO_3(aq)+BaCl_2(aq)\rightarrow 2AgCl(s)+Ba(NO_3)_2(aq)$

3) Change in color

4) Production of gas

hich of the followings decrease the affinity of adult Hb with O2? A. 2,3 BPG B. hydrogen ion C. CO2 D. Ferrous ion

Ivahew [28]

Answer:

A. 2,3 BPG

Explanation:

2,3-bisphosphoglycerate (BPG), otherwise known as 2,3-DPG, enables the transition of hemoglobin from a very high-oxygen-affinity state to a reduced-oxygen-affinity state.

Tissues hemoglobin oxygen affinity is reduced by numerous physiological factors including.

1. Temperature Increased,

2. Carbon dioxide,

3. Acid and

4. 2,3-Bisphosphoglycerate (2,3-BPG)

all of which can contribute to decrease the oxygen affinity of hemoglobin which favours unloading and increased oxygen availability to our body cells.
