<h3>What does an empirical formula mean ? </h3>

- Empirical formula represents a molecule with its elements combined in simplest ratio, it's not necessarily same as the form in which the compound really exists in the nature. Hence we can say that empirical formula shows the simple ratios in which atoms combined to form a molecule.

For example : Hydrogen peroxide

- Hydrogen peroxide exists in nature as $\sf H_2O_2$ , which is its molecular formula.

but it's empirical formula will be H0 [ simplest ratio of 1 : 1 ]

Therefore, the correct choice is :

C. $\sf H_2O$

Define and give an example of an acid and of a base.

Debora [2.8K]

A Brønsted-Lowry acid is defined as a compound that gives hydronium ions to another compound—for example, hydrochloric acid gives H+ ions to compounds it reacts with. Brønsted-Lowry bases are compounds that can accept hydronium ions—when ammonia gets a hydronium ion from HCl, it forms the ammonium ion.

The individual components of a solution_____.

Misha Larkins [42]

Its been awhile since I've dabbled in chemistry, but i do know that A isnt the answer because the question says solution, not mixture. This looks somewhat like a trick question, it says individual components, so the answer would be C. This is because the individual components do react to form a compound. B and D would be true if it didnt say individual components, so the question is basically focusing on only one ingredient, not the whole solution. Answer: C

How is an oxidation half-reaction written using the reduction potential chart? How is the oxidation potential voltage determined

insens350 [35]

Oxidation half reaction is written as follows when using using reduction potential chart
example when using copper it is written as follows
CU2+ +2e- --> c(s) +0.34v
oxidasation is the loos of electron hence copper oxidation potential is as follows
cu (s) --> CU2+ +2e -0.34v

Salivary amylase is an enzyme produced by the salivary glands that breaks down carbohydrates. What will happen to this enzyme as

o-na [289]

Answer:

It will be denatured.

Explanation:

Salivary amylase works best at pH 6.8.

At pH 2.5, its activity will decrease enormously as it becomes denatured by the high acidity of the stomach contents.
