S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

Chemistry
1 answer:
lina2011 [118]2 years ago
7 0

Answer:

43.5 moles of HNO₃.

Explanation:

The balanced equation for the reaction is given below:

S + 6HNO₃ —> H₂SO₄ + 6NO₂ + 2H₂O

From the balanced equation above,

6 moles of HNO₃ reacted to produce 2 moles of H₂O.

Finally, we shall determine the number of mole of HNO₃ required to produce 14.5 moles of H₂O.

This can be obtained as illustrated below:

From the balanced equation above,

6 moles of HNO₃ reacted to produce 2 moles of H₂O.

Therefore, Xmol of HNO₃ will react to produce 14.5 moles of H₂O i.e

Xmol of HNO₃ = (6 × 14.5)/2

Xmol of HNO₃ = 43.5 moles

Therefore, 43.5 moles of HNO₃ is required to produce 14.5 moles of H₂O.

How do you do these?
Agata [3.3K]

Solve these problems like weighted averages:

The first one:

Multiply the masses (isotope numbers) by the decimal form of the percentage. Add them

0.076 (6) + 0.924 (7) = 6.924


The second one:

0.2 (10) + 0.8 (11) = 10.8


If you think about it, these answers make sense. 6.924 is much closer to 7 than to 6 (since there's a lot more lithium-7 than there is lithium-6). 10.8 is closer to 11 than to 10.

Which molecule has the greatest difference in electronegativity (DE) between the two different elements? A. CO_2 B. H_2S C. NH_3
Natalka [10]

Answer:

Water has the greatest ΔEN

ΔEN H₂O → 3.4 - 2.1 = 1.3   Option D.

Explanation:

We should find the Electronegativity data in the Periodic table for all the elements:

C : 2.6

O: 3.4

H: 2.1

S: 2.6

N: 3.0

a. ΔEN CO₂ → 3.4 - 2.6 = 0.4

b. ΔEN H₂S → 2.6 - 2.1 = 0.5

c. ΔEN NH₃ → 3 - 2.1= 0.9

d. ΔEN H₂O → 3.4 - 2.1 = 1.3
