Answer:
C10H200
Explanation:
The molecular formula C10H20O (molar mass : 156.27 g/mol) may refer to: Citronellol. Decanal.
a. volume of NO : 41.785 L
b. mass of H2O : 18 g
c. volume of O2 : 9.52 L
<h3>Further explanation</h3>
Given
Reaction
4 NH₃ (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (l)
Required
a. volume of NO
b. mass of H2O
c. volume of O2
Solution
Assume reactants at STP(0 C, 1 atm)
Products at 1000 C (1273 K)and 1 atm
a. mol ratio NO : O2 from equation : 4 : 5, so mo NO :
volume NO at 1273 K and 1 atm
b. 15 L NH3 at STP ( 1mol = 22.4 L)
mol ratio NH3 : H2O from equation : 4 : 6, so mol H2O :
mass H2O(MW = 18 g/mol) :
c. mol NO at 1273 K and 1 atm :
mol ratio of NO : O2 = 4 : 5, so mol O2 :
Volume O2 at STP :
Use the equation C = εA/d
Where C = capacitance, A = area, d = distance between plates & ε = electrical permittivity of the medium between the plates
Answer:
Group 1 and 2 elements
Explanation:
Nitrogen, a non-metal will form ionic bonds with most group 1 and group 2 metals on the periodic table.
How does ionic bonds form?
- They are bonds formed between a highly electronegative specie and one with very low electronegativity.
- As such, ionic bonds forms between metals and non-metals
- In this bond type, the metal due to its electropositive nature will transfer electrons to the non-metals for it to gain.
- The non-metals becomes negatively charged as the metal is positively charged.
- The electrostatic attraction between the two specie leads to the formation of ionic bonds.
Most metals in group 1 and 2 fits in this description. Some of them are calcium, magnesium, lithium, Barium e.t.c.
It mostly favors group 2 metals.
<span>Percent yield is the measured recovery of a substance in grams divided by the theoretical amount of substance expected in grams (times 100 to convert to %). Undissolved Aluminum trihydroxide would add mass to the Aluminum sulphate one is making here. The measured mass would be inaccurately high, increasing the percent yield calculated.</span>
