You need to have in mind the following equations given two different notations:
<span>In Organic notation you write the lacti acid calculation like this: </span>
<span>CH3CH(OH)COOH(aq) <----> CH3CH(OH)COOH-(aq) + H+ </span><span>(aq) </span>
<span>Now the simplified formula equation will be: </span>
<span>HC3H5O3(aq) <-----> H+(aq) + C3H5O3(aq) </span>
<span>0.110 - x M .................. x M ............. x M </span>
havign the regular formula you proceed as follows:
<span>Ka = [H+] [C3H5O3] / [HC3H5O3] </span>
<span>1.4x10^-4 = (x)(x) / (0.110 - x)
Do the maths and you will get the answer.

The bacteria are chemoautotrophs. These microorganisms make use of molecules that are inorganic for energy and using carbon dioxide for carbon source. The process of obtaining energy is called chemosynthesis which uses molecules like hydrogen sulfide, ferrous iron, ammonia and the like.

Answer:
0.21L
Explanation:
To solve this problem, we make use of Boyle’s law. It states that at constant temperature, the volume of a fixed mass of gas is inversely proportional to its pressure.
Mathematically PV = K
P1V1 = P2V2
P1 = 1 atm
V1 = 1.45L
P2 = 70 atm
v2 = ?
From the equation form, we know that
V2 = P1V1/V2
V2 = ( 1 * 1.45)/70
V2 = 0.021L
The answer is C. Air inside a balloon. This is because gases are much more affected by thermal expansion and contraction compared to liquids and solids. The reason behind this is that gas molecules are very loosely packed, so even the slightest changes in temperature have a big effect on its pressure and volume. If the air inside a balloon has a temperature rise, the tendency is for the balloon to expand and potentially explode.
Liquids are also affected by thermal expansion or contraction, but not as much as gases. Solids tend to maintain their shape under thermal expansion or contraction.
