Besides producing hydrogen ions in water, all Arrhenius acids have a few things in common. They have pH values anywhere from 0 up to 7, they taste and smell sour and they will turn pH paper pink, red, or orange.
<h3>What Arrhenius acids?</h3>
A substance that raises the concentration of H+ ions in an aqueous solution is known as an Arrhenius acid. Traditional Arrhenius acids are highly polarized covalent substances that dissociate in water to form an anion (A-) and the cation H+.
Aqueous Arrhenius acids have distinguishing characteristics that serve as a useful definition of an acid. Acids can turn blue litmus red, produce aqueous solutions with a sour taste, and react with bases and some metals (like calcium) to generate salts. The Latin word acidus/acre, which means "sour," is where the word acid originates.
Although the precise definition solely refers to the solute, the term "acid" is sometimes used to refer to an aqueous solution of an acid that has a pH lower than 8.

I think I have done a question like this before and i'm pretty sure your answer would be the 2nd one 1s22s22p4. I'm not 100% sure but try it at least.
<span>I didn't know Selenium was considered organic? :P atoms form ions that mimic the electronic structure of noble gases. so add or subtract electrons from the atom to achieve the configuration of a noble gas.</span>
Explanation:
Characteristics of good solvent choice for the recrystallization.
1. Water has low solubility of benzoic acid at room temperature.
2. Cold water's low solubility of benzoic acid allows for the high concentration production of crystal. And these crystals could be easily soluble in hot water.
3. Water dissolves soluble impurities well at the room temperature.
Answer :
Incorrect
Explanation : In the given solution set of Ax = b;
is set of all vectors to form w=
p +
here
is is any solution of the equation Ax = 0;
this stands to be incorrect, as the correct would only exists when some vector
p is found to be like this
Ap=b
