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.

Answer:
104.84 moles
Explanation:
Given data:
Moles of Boron produced = ?
Mass of B₂O₃ = 3650 g
Solution:
Chemical equation:
6K + B₂O₃ → 3K₂O + 2B
Number of moles of B₂O₃:
Number of moles = mass/ molar mass
Number of moles = 3650 g/ 69.63 g/mol
Number of moles = 52.42 mol
Now we will compare the moles of B₂O₃ with B from balance chemical equation:
B₂O₃ : B
1 : 2
52.42 : 2×52.42 = 104.84
Thus from 3650 g of B₂O₃ 104.84 moles of boron will produced.
