Answer:
Mass of nitrogen dioxide produced = 4.6 g
Explanation:
Given data:
Volume of ammonia = 2.30 L
Mass of nitrogen dioxide produced = ?
Solution:
Chemical equation:
4NH₃ + 7O₂ → 4NO₂ + 6H₂O
Number of moles of ammonia at STP:
PV = nRT
n = PV/RT
n = 1 atm × 2.30 L / 0.0821 atm.L/K.mol × 273 K
n = 2.30 atm .L / 22.414 atm.L/mol
n = 0.1 mol
Now we will compare the moles of ammonia with nitrogen dioxide from balance chemical equation.
NH₃ : NO₂
4 : 4
0.1 : 0.1
Mass of NO₂:
Mass = number of moles × molar mass
Mass = 0.1 mol × 46 g/mol
Mass = 4.6 g
Based on the Hund's Rule, the three electrons in a 2p orbital are arranged as shown in option C.
<h3>What is an orbital?</h3>
The term orbital refers to a region in space where there is a high probability of finding the electron. We know that an electron in an atom could be defined by the use of four sets of quantum numbers which are;
- The principal quantum number
- The orbital quantum number
- The spin quantum number
- The magnetic quantum number
Hund's rule states that, electrons occur singly before pairing takes place. In this case, we can see that the only arrangement that obeys the Hund's Rule is option C.

Answer:
Number of moles = 2.89 mol
Explanation:
Given data:
Number of moles of sugar = ?
Mass of sugar = 990 g
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of C₁₂H₂₂O₁₁:
12× 12 + 22×1.008 + 16×11 = 342.2 g/mol
Number of moles = 990 g / 342.2 g/mol
Number of moles = 2.89 mol
C. Sugar is the solute and water is the solvent since sugar is the one dissolving and water is what the sugar is dissolving in.
