The correct answer is C. Excess food with cause a population to grow.
Reaching the carrying capacity causes a population to stop growing. Disease and crowded conditions may even cause a population to decline, so those can be ruled out.
Answer:
7 methyl 3 octyne is the answer option D
Answer:
0.16 J/g℃
Explanation:
We have the following data:
heat = 1,200 J
mass of metal = m = 150 g
change in temperature = ΔT = 50.0℃
The heat absorbed is calculated by using the following equation:
heat = m x Cp x ΔT
So, we introduce the data in the equation to calculate the specific heat of the metal (Cp), as follows:
Cp = heat/(m x ΔT) = (1,200 J)/(150 g x 50.0℃) = 0.16 J/g℃
Answer:
Explanation:
10)
Given data:
Mass of iron = 5 g
Mass of FeO = ?
Solution:
Chemical equation:
2Fe + O₂ → 2FeO
Number of moles of iorn:
Number of moles = mass/ molar mass
Number of moles = 5g / 55.845 g/mol
Number of moles = 0.09 mol
Now we will compare the moles of FeO with Fe.
Fe : FeO
2 : 2
0.09 : 0.09
Theoretical yield of FeO:
Mass of FeO:
Mass = number of moles × molar mass
Mass = 0.09 mol × 71.844 g/mol
Mass = 6.47 g
11)
Given data:
Mass of iron = 5 g
Mass of Fe₂O₃ = ?
Solution:
Chemical equation:
4Fe + 2O₂ → 2Fe₂O₃
Number of moles of iron:
Number of moles = mass/ molar mass
Number of moles = 5g / 55.845 g/mol
Number of moles = 0.09 mol
Now we will compare the moles of FeO with Fe.
Fe : Fe₂O₃
4 : 2
0.09 : 2/4×0.09 = 0.045
Theoretical yield of Fe₂O₃:
Mass of Fe₂O₃:
Mass = number of moles × molar mass
Mass = 0.045 mol × 159.69 g/mol
Mass = 7.2 g
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.
