A solution with a ph of 2 has a h+ ion concentration that is _____ than a solution with a ph of 4

Chemistry

A  solution with  a Ph  of   2  has  a  H+  ion  concentration  that  is two  times  greater  than  a  solution  with  a  ph  of  4.      The  Ph  of  2  and 4 indicate  that  the  solution  is   acidic since  they  are  less  than  PH  of  7. The  H+   ions  are more present   when  the  solution is  acidic  but   the  Ph  differ  with  concentration  H+  ions. The  solution  with  a  Ph  of  2  has  more  H+    than  the  solution  with  Ph  of  4  thus  the  solution with Ph  of  2  has  more  hydrogen  ions  than  that  of  4

Write a chemical formula for each molecular model. (Blue ball represents nitrogen atom, red ball represents oxygen atom, white b
Marysya12 [62]

Answer:

See answer below

Explanation:

In this case, you are missing the picture. Luckily I found one on another site, so I hope is the one you are asking for. If not, please post again with the picture.

According to the picture below, you need to write a chemical formula for each molecular model.

To do this, is just simple. Let's see each model per separate.

In the first model, we have a blue ball and three white balls. According to the nomenclature of the question a blue ball represents nitrogen atoms and white ball represents hydrogen, therefore, we have an atom of nitrogen bonded to three atoms of hydrogens, so, the chemical formula should be:

NH₃: This molecule corresponds to the Ammonia molecule.

The second picture, shows 4 black balls (representing an atom of carbon each) and each black ball holds a determinated number of white balls. The two of the middle have two white balls each, and the terminals have 3 white balls, therefore, the molecule should be the following:

CH₃ - CH₂ - CH₂ - CH₃: this corresponds to the butane

Finally, the last picture shows a yellow ball (which represents sulphur) and three red balls (representing oxygen each), so, the molecule that represents this would be:

SO₃: this is the sulfite ion.

Which is the strongest base?
DochEvi [55]

Answer:

The answer to your question is: [H+] = 10⁻¹²

Explanation:

Remember that pH = -log [H+], then, in this exercise we need to calculate the pH of the substances and compare the results, the one which the higher value will be the strongest base.

a) [H+] = 10^-9      pH = -log[10⁻⁹] = 8

b) [H+] = 10^-11     pH = -log[10⁻¹¹] = 10

c) [H+] = 10^-10     pH = -log[10⁻¹⁰] = 9

d) [H+] = 10^-12    pH = -log[10⁻¹²] = 11      This is the strongest base
