1 answer:
Answer:
The correct answer is :It is a molecule composed of carbon and hydrogen only.
Explanation:
Hydrocarbons are defined as compounds which majorly made up carbon and hydrogen.There three types of hydrocarbons:
- Alkanes : These are saturated hydrocarbons with single bond present in between two carbon atoms.The general structure of an alkane is:
- Alkene :These are unsaturated hydrocarbons with double bond present in between two carbon atoms.The general structure of an alkene is:
- Alkyne :These are unsaturated hydrocarbons with triple bond present in between two carbon atoms.The general structure of an alkyne is:

Answer: The possible molecular formula will be
Explanation:
Mass of C= 27.3 g
Mass of O = 72.7 g
Step 1 : convert given masses into moles.
Moles of C =
Moles of O =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For C =
For O =
The ratio of C : O = 1: 2
Hence the empirical formula is
The possible molecular formula will be=
Answer:
a)
b)
c)
Explanation:
Hello,
a) In this case, the given height in cm is:
And the radius in cm is:
Thus, the volume in cubic centimeters which is also equal in mL (1cm³=mL) is:
b) In this case, the given height in mm is:
And the radius in mm is:
Thus, the volume in cubic millimeters is:
c) Finally, since 1000 mL equal 1 L, the required density in g/L turns out:
