Given
the structure of the alkanes
Required
match the image to the name
Solution
Alkanes are saturated hydrocarbons with all of the carbon bonds being single bonds
General formula:
If we look at the picture, we define the black atom as Carbon and the branch is Hydrogen
To determine the name of the alkane, all we have to do is count the number of Carbon atoms
Butane : C₄H₁₀ : 4 C atoms
Methane : CH₄ : 1 C atom
Ethane : C₂H₆ : 2 C atoms
Propane : C₃H₈ : 3 C atoms
Answer: The earth's atmosphere gets thinner with the increase in altitude. The earth's atmospheric layers are Troposphere, Stratosphere, Mesosphere, Ionosphere .

Answer: Absorption. The transfer of energy carried by light waves to particles of matter.
Explanation:
Answer:
Mass = 100.8 g
Explanation:
Given data:
Mass of sulfur formed = ?
Mass of water formed = 37.4 g
Solution:
Chemical equation:
2H₂S + SO₂ → 3S + 2H₂O
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 37.4 g/ 18 g/mol
Number of moles = 2.1 mol
Now we will compare the moles of water and sulfur.
H₂O : S
2 : 3
2.1 : 3/2×2.1 = 3.15
Mass of sulfur:
Mass = number of moles × molar mass
Mass = 3.15 mol × 32 g/mol
Mass = 100.8 g
The answer is (2). To calculate the density, you need to divide the mass with volume. When doing division, the significant figures of result is the minimal of the numbers using before. So the answer is 2.
