Hopefully this is correct and I believe CO2 is bad because the cells in the body need oxygen to then release energy from food efficiently by carrying out aerobic respiration. And a waste product of aerobic respiration is Carbon Dioxide. And Carbon dioxide must be removed from our bodies or it them makes the blood dangerously acidic.
Hope this helps :)
a. vinegar
b. Mineral deficiencies in the body can make joint pain worse. Because Vinegar contains the calcium, magnesium, potassium, and phosphorus your body needs, it helps as a supplement and therefore reduces pain.
1. in making fertilisers which are chemical compounds or salts to increase fertility of soil.
2. lithium hydroxide is used in space because of its high absorption of carbon dioxide and the small amount of heat produce by the reaction.
3. Acid rain has a lower pH than "normal" rain . Rain is naturally somewhat acidic with a pH between 5.0-5.5 typically. Acid rain has a pH that is below this: 4.4-4.2
4. lemon juice is an anti bacterial and a good germicidal solution which helps in removing the unseen bacteria on our hands.

the variable that we change in an experiment is the Independent Variable. The dependent variable is the outcome and the constant is what remains the same throughout the experiment.
Answer:
The vapor pressure of ethanol in the solution is 10,27 kPa
Explanation:
To obtain the vapor pressure of a solution it is necessary to use Raoult's law:
<em>(1)</em>
The moles of ethanol are:
18,00mL×
×
= 0,3083 mol Ethanol.
Moles of benzoic acid:
12,55 g×
= 0,1028 mol benzoic acid.
Thus, mole fraction of solvent, X, is:
=<em> 0,7499</em>
Replacing this value in (1):
= <em>10,27 kPa</em>
<em></em>
I hope it helps!
Answer:
The water ligands surrounding the cobalt metal center are being replaced by ethylenediamine and chloride ligands which results in a different crystal field splitting. Thus, the energy associated with electron transitions between the do-orbitals will differ for the two compounds showing a color change.
Explanation:
The five d-orbitals are usually degenerate. Upon approach of a ligand, the d-orbitals split into two sets of orbitals depending in the nature of the crystal field.
The magnitude of crystal field splitting is affected by the nature of the ligand. Ligands having filled p-π orbitals such as ethylenediamine lead to greater crystal field splitting.
The change in the colour that takes place when ethylenediamine is added to the solution of cobalt(II) chloride occurs due to a different crystal field splitting pattern. Thus, the energy associated with electron transitions between the d-orbitals now differ for the two compounds showing a color change.
