Which one of the following is a common acid?

a. banking soda
b. antacid
c. ammonia
d. vitamin c

Hi!

The correct option is D. Vitamin C.

Vitamin C, or more commonly ascorbic acid, is considered a weak sugar acid that is widely available in fruits and vegetables. It is structurally related to glucose, and has the molecular formula of C6H8O6, and is the only acidic substance of the options.

Baking Soda contains sodium bicarbonate which dissolves in water to yield a basic solution.

Antacids may be aluminium hydroxide or sodium bicarbonate that react with acids to neutralize the pH. Antacids are normally used to neutralize the pH of the stomach in people with stomach ulcers.

Ammonia (NH3) is essentially considered a weak base, which dissolve in water to yield hydroxide ions and ammonium ions.

Hope this helps!

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
