I would say the water is the solvent and carbon dioxide is the solute. Carbon dioxide is usually introduced to water under pressure and then sealed. Once the cap is removed, the carbon dioxide starts to escape since it is then under low pressure. Sometimes, natural groundwater has dissolved carbon dioxide in it but most of our soft drinks have it artificially introduced. Water plus carbon dioxide also form carbonic acid and this can give the tingly sensation on the tongue when drinking soft drinks.
C. They are genetically capable of making chlorophyll
The element that has the smallest atomic radius is <u>titanium</u>
<em><u>explanation</u></em>
- Calcium,potassium, scandium and titanium are in period 4 in the periodic table.
- Generally the atomic radius decreases across the period (from the left to the right) . This is because across the period there is increase in nuclear charge which make electrons been strongly attracted to the nuclear.
- Titanium is in atomic number 22 thus it has more nuclear charge that calcium,potassium and scandium therefore titanium has the smallest atomic radius.
Explanation:
Number of oxygen molecules = 10 billion = 
Number of hydrogen molecules = 10 billion =
Number of molecules of hydrogen peroxides = 10 billion =
Moles of oxygen gas :
Moles of hydrogen gas :
Moles of hydrogen gas :
Number of moles in hydrogen gas, oxygen gas and hydrogen peroxide is same.
Total number of atoms in 
molecules of oxygen:
(2 atoms in 1 molecule)
Total number of atoms in molecules of hydroegn :
(2 atoms in 1 molecule)
Total number of atoms in molecules of hydrogen peroxide:
(4 atoms in 1 molecule)
Number of oxygen atoms and number of hydrogen atoms are equal but individually they are not equal to number of atoms in hydrogen peroxide.
