Answer:An atom has 5 protons, 5 electrons and 6 neutrons The atomic number = number of protons = number of electrons = 5 The mass number = 5 protons + 6 neutrons = 11
Structural formula is the formula which shows the arrangement of atoms in the molecule of a compound
2-methylbutan-2-ol is an alcohol which the functional group (OH) is attached in carbon number two and also has methyl group in carbon number two.
The structural formula of 2=methylbutan-2-ol is as the attachment below

(a) 0.294 mol silver =
(b) 8.98 * 10-3 mol sodium chloride -
(c) 23.3 mol carbon dioxide =
(d) 0.310 mol nitrogen (N2) = 
Explanation:
In one mole there are
atoms/molecules
(a) 0.294 mol silver =
(b) 8.98 * 10-3 mol sodium chloride -
(c) 23.3 mol carbon dioxide =
(d) 0.310 mol nitrogen (N2) =
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.
