In a 0.01 M solution of 1,4-butanedicarboxylic acid, HOOCCH2CH2COOH (Ka1 = 2.9 x 10-5,
azamat

Answer:

The correct answer is B) HOOCCH2CH2COOH(aq)

Explanation:

Both Ka1 and Ka2 are low, so the acid will dissociate only slightly into HOOCCH2CH2COO- ions and even more slightly into -OOCCH2CH2COO- ions. The concentration of hydronium ions (H₃O⁺) will be consequently low. The species that will be in the highest concentration will be HOOCCH2CH2COOH (the weak acid not dissociated).

Nitroglycerin, used both in medicine and as an explosive, can be prepared by the carefully controlled reaction of glycerol (C3H8
vesna_86 [32]

The mass of nitric acid (HNO₃) required for the production of 2.8 g of nitroglycerin? (C₃H₅N₃O₉) is 2.33 g

We'll begin by calculating the mass of HNO₃ that reacted and the mass of C₃H₅N₃O₉ produced from the balanced equation. This can be obtained as follow:

C₃H₈O₃ + 3HNO₃ —> C₃H₅N₃O₉ + 3H₂O

Molar mass of HNO₃ = 1 + 14 + (16×3)

= 1 + 14 + 48

= 63 g/mol

Mass of HNO₃ from the balanced equation = 3 × 63 = 189 g

Molar mass of C₃H₅N₃O₉ = (12×3) + (1×5) + (14×3) + (16 × 9)

= 36 + 5 + 42 + 144

= 227 g/mol

Mass of C₃H₅N₃O₉ from the balanced equation = 1 × 227 = 227 g

<h3>SUMMARY:</h3>

From the balanced equation above,

227 g of C₃H₅N₃O₉ were produced by 189 g of HNO₃.

Finally, we shall determine the mass of HNO₃ that will produce 2.8 g of C₃H₅N₃O₉. This can be obtained as follow:

From the balanced equation above,

227 g of C₃H₅N₃O₉ were produced by 189 g of HNO₃.

Therefore,

2.8 g of C₃H₅N₃O₉ will be produce by = \frac{2.8 * 189}{227} \\\\ = 2.33 g of HNO₃

Thus, the mass of nitric acid (HNO₃) required for the production of 2.8 g of nitroglycerin? (C₃H₅N₃O₉) is 2.33 g
