Answer:
The answer to your question is: C₂H₆O₁ = C₂H₆O
Explanation:
Data
CxHyOz
mass = 40 g produced 76.40 g of CO2
46.96 g of H2O
Empirical formula = ?
Process
CxHyOz + O2 ⇒ CO2 + H2O
44g of CO2 -------------------- 12 g of Carbon
76.40 g of CO2 --------------- x
x = 20.84 g of Carbon
12 g of Carbon --------------- 1 mol
20.84 g of C --------------- x
x = (20.84 x 1) / 12
x = 1.74 mol of Carbon
18 g of H2O -------------------- 2 g of H
46.96 g of H2O -------------- x
x = (46.96 x 2) / 18
x = 5.22 g of H
1 g of H ------------------------ 1 mol of H
5.22 g of H ------------------- x
x = 5.22 mol of H
Mass of Oxygen = 40 - 20.84 - 5.22g
= 13.94 g
16 g of Oxygen ---------------- 1 mol
13.94 g of O -------------------- x
x = 0.87 mol of O
Divide by the lowest number of moles
Carbon = 1.74 / 0.87 = 2
Hydrogen = 5.22 / 0.87 = 6
Oxygen = 0.87 / 0.87 = 1
Empirical formula
C₂H₆O₁ = C₂H₆O
The answer is b. the water molecules are more closely packed together in ice than in water <span />
Answer:
Recall that, at the boiling point, we observe that both liquid and gas are at equilibrium with one another. This is true at every combination of applied pressure and boiling point temperature. ... The applied pressure will be greater than the vapor pressure, and all of the gas will condense into the liquid
The name of the compound by using the <u>IUPAC nomenclature of organic compounds</u> is 1 -octene. The correct option is the last option - 1-octene.
<h3>Nomenclature of Organic compounds</h3>
From the question, we are to determine the name of the given molecule.
To name the compound, we will follow the IUPAC rules.
Some of IUPAC rules are
- Find the longest continuous carbon chain. Determine the root name for this parent chain.
- For Alkenes (organic compounds with double bond), number the chain of carbons that includes the C=C so that the C=C has the lower position number. Change “ane” to “ene” and assign a position number to the first carbon of the C=C.
The given compound has 8 carbons and a double bond. The root name of the compound is octane.
By <u>IUPAC rules</u>, the compound is an <u>Octene</u>.
Since the double bond is between carbon-1 and carbon-2. The compound becomes 1-octene.
Hence, the name of the compound by using the <u>IUPAC nomenclature of organic compounds</u> is 1 -octene. The correct option is the last option - 1-octene.
