An acid is a substance that increases the concentration of h3o ions in solution. look at the reaction below of phenol (c6h5oh) with water: upper c subscript 6 upper h subscript 5 upper o upper h (a q) plus upper h subscript 2 upper o (l) right arrow upper c subscript 6 upper h subscript 5 upper o superscript minus (a q) plus upper h subscript 3 upper o superscript plus (a q). which reactant acts as an acid by contributing a h ion to create h3o in the chemical equation <u>The reactant that acts as an acid, by contributing an H⁺ ion to create H3O+ in the chemical equation is C₆H₅OH.</u>
<h3>What is
acid ?</h3>
A Brnsted-Lowry acid or Lewis acid is a molecule or ion that can either donate a proton (the hydrogen ion, H+) or establish a covalent bond with an electron pair.
Proton donors, also known as Brnsted-Lowry acids, are the first class of acids. Proton donors, also referred to as Arrhenius acids, generate the hydronium ion H3O+ under the unique situation of aqueous solutions. The Arrhenius theory was expanded upon by Brnsted and Lowry to take non-aqueous solvents into account. A hydrogen atom is typically bound to a chemical structure in a Brnsted or Arrhenius acid that is still energetically advantageous after the loss of H+.
Aqueous Arrhenius acids have distinguishing characteristics that serve as a useful definition of an acid.

Answer:
You may be saving someone from a rock slide, where the rocks will fall at any time, before they fall they have potential energy.
Answer:
387.62, 83.33%
Explanation:
Given:
720g of Sucrose produces 323g ethanol.
<h3>Theoretical yield</h3>
To calculate the theoretical yield, you can use a mole-to-mole ratio. Assuming that there is excess H2O, you can calculate the theoretical yield like so:
<h3>Percent Yield</h3>
An easy way to find percent yield is
So, plug the numbers in.
So, the percent yield is 83.33%.
Answer:
the chemical element of atomic number 2, an inert gas which is the lightest member of the noble gas series.
Explanation:
Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.
The oxidizing agent is the one that is reduced which is also the one who gains electron. The reducing agent is the one that is oxidized which is also the one who loses electron. Thus,
a. The substance H2S is the one oxidized.
b. The substance I2 is the one reduced.
c. The oxidizing agent is I2.
d. The reducing agent is H2S.
