Given molecule:
CH3-CH2-CH2-CH2-CH2-CH2-CH3
- The molecule contain only C and H atoms, hence it is a hydrocarbon
- The C atoms in the linear chain are linked together by carbon-carbon single bonds, hence it is a saturated compound
- It has 7 C atoms and 16 H atoms, hence the molecular formula is C7H16
-The molecular formula can be generally represented as CnH2n+2 where n = 7. This corresponds to the general molecular formula for alkanes
The given molecule is best described as an <u>alkane</u>
Answer:
Physical geography is one of the two fields of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere
Answer:
The correct answer is 0.206 moles
Explanation:
According to the given scenario, the calculation of the number of moles of ammonium chloride is available in the resulting solution is given below:
Given that
Amount of 
is 11.0 grams
And, the volume is 235 mL
Now the molar mass of is 53.49g/mol
So, the number of moles presented is
= 11.0 ÷ 53.49
= 0.206 moles
hence, the number of moles of ammonium chloride are available in the resulting solution is 0.206 moles
Answer:
V = 43.95 L
Explanation:
Given data:
Mass of CH₄ decomposed = 15.63 g
Volume of H₂O produced at STP = ?
Solution:
Chemical equation:
CH₄ + 2O₂ → 2H₂O + CO₂
Number of moles of CH₄:
Number of moles = mass/molar mass
Number of moles = 15.63 g/ 16 g/mol
Number of moles = 0.98 mol
Now we will compare the moles of H₂O with CH₄.
CH₄ : H₂O
1 : 2
0.98 : 2×0.98 = 1.96 mol
Volume of hydrogen:
PV = nRT
1 atm × V = 1.96 mol × 0.0821 atm.L/mol.K × 273.15 K
V = 43.95atm.L / 1atm
V = 43.95 L
It doesn't because pepper does not dissolve
