The correct answer is c. H3PO4 2H++ HPO42¯(Phosphoric acid)
<h3>
Phosphoric acid</h3>
Known also as ortho-phosphoric acid, phosphoric acid is a triprotic acid that occurs as a viscous liquid. It irritates or corrodes human skin, eyes, and other mucous membranes as well as those of experimental animals. However, the irritancy potential of its salts is much smaller. When mice were exposed through inhalation, moderate toxicity was seen. Both phosphate salts and phosphoric acid have been shown to enhance the action of recognized carcinogens, however phosphoric acid alone is neither genotoxic nor carcinogenic. Typically, irrigation or water flushing are used to treat exposures. As a food addition to different cola drinks, phosphoric acid has attracted a lot of attention but also generated a lot of debate due to its potential for negative effects.

<span>It is said
that the carbon atom is a tetra valence which means, it contains 4
covalent bonds that can be bonded with other atoms. Therefore, it needs 4
hydrogen atoms to bind into 1 carbon atom. Carbon Atom contains a total of
6 electrons that occupies the 2 shells which is the K (have 2 electrons)
and L (have 4 electrons) shells. The
outermost shell of carbon atoms that contains 4 electrons is called as
valence shell. In order to complete its octet, carbon Atom needs other
atoms to share their valence electrons.</span>

Answer:
Explanation:
Using the ideal gas equation as follows:
PV = nRT
Where:
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
Based on the information provided in this question;
P = 1.6atm
n = 4.4 moles
R = 0.0821 L*atm/mol*K
T = 32.9°C = 32.9 + 273 = 305.9K
V = ?
