Which of these compounds are oxoacids (also known as oxyacids)?
devlian [24]

At the very least, an oxoacid must 1) be an acid and 2) contain oxygen.

Ba(OH)2 (barium hydroxide) is a strong base. HCN, HF, and hydrochloric acid (HCl) don't contain oxygen.

Nitrous acid (HNO2) is an acid, and it contains oxygen. And the acidic hydrogen is bonded to an oxygen. Thus, nitrous acid qualifies as an oxoacid.

I don't know if H2PO4 is a typo; if not, then it would properly be written as H2PO4⁻ since it's the first deprotonation product of phosphoric acid, H3PO4. In any case, H2PO4⁻ is still acidic, albeit weakly, and its acidic hydrogens are bonded to the oxygen atoms. Thus, "H2PO4" would qualify as an oxoacid (for that matter, H3PO4 would also be an oxoacid).

Chloric acid (HClO3) is an acid, and it contains oxygen; its acidic hydrogen is bonded to an oxygen atom. Thus, chloric acid qualifies as an oxoacid.

The synthesis of ATP by oxidative phosphorylation, using the energy released by movement of protons across the membrane down the
AlexFokin [52]

Answer:

It is an example of coupling an exogenic reaction to an endogenic reaction.

Explanation:

The endergonic reaction is typically being pushed by coupling it to strongly exergonic reaction. This is in most cases via shared intermediates. Most chemical reactions are endergonic in nature. In other word, the are not spontaneous (i.e ΔG>0). Energy must also be applied externally to initiate the reactions. The reactions can also be coupled to exergonic reactions (with  ΔG<0) to initiate them through a process known as share intermediate. Because Gibbs Energy can be summed up (i.e is a state function), the combined  ΔG  of the coupled reaction will be thermodynamically favorable.  The decomposition of calcium carbonate is a typical example.

A compound that donates hydrogen ions to a solution is.
jenyasd209 [6]

Your answer is, an acid

<u>Acid</u>

An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution.

<u>Acid Rain</u>

Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. Most water, including drinking water, has a neutral pH that exists between 6.5-8.5, but acid rain has a pH level lower than this and ranges from 4-5 on average.

<u>Examples of Acids</u>

  • sulfuric acid
  • nitric acid
  • hydrochloric acid
  • phosphoric acid
  • carboxylic acid
  • sulfonic acid

Thus, <u>an acid</u> is your answer.

What is the pH of a solution with [H+] of 1x10^-8 M?*<br> 15<br> -8<br> 8<br> 80
Serga [27]

Answer:

<h2>8</h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

From the question we have

ph  =  -  log(1 \times  {10}^{ - 8}  )  \\  = 8

We have the final answer as

<h3>8 </h3>

Hope this helps you

If the [H+] = 0.01 M, what is the pH of the solution, and is the solution a strong acid, weak acid, strong base, or weak base?
lana66690 [7]

Answer:

2, strong acid

Explanation:

Data obtained from the question. This includes:

[H+] = 0.01 M

pH =?

pH of a solution can be obtained by using the following formula:

pH = –Log [H+]

pH = –Log 0.01

pH = 2

The pH of a solution ranging between 0 and 6 is declared to be an acid solution. The smaller the pH value, the stronger the acid.

Since the pH of the above solution is 2, it means the solution is a strong acid.
