Answer: Pentane
Explanation: According to the IUPAC(International Union of Pure and Applied Chemistry) the name of this compound will be pentane. This compound belongs to the alkane category, which has single bond between the carbon atoms. This naming is done on the basis of the number of carbon atoms and the nature of the chemical bond between the carbon atoms.
Word roots are selected based on the number of carbon atoms
1 C atom = Meth
2 C atom = Eth
3 C atom = Prop
4 C atom = But
5 C atom = Pent
6 C atom = Hex
7 C atom = Hept
8 C atom = Oct
9 C atom = Non
10 C atom = Dec
Suffixes are added based on the nature of chemical bond between the carbon atoms.
Word root + suffix (here: ane)
Potassium Sulfate = K₂SO4
SO4 = negative 2, so you need 2 K+ ions to counteract it, hence K₂
Answer: The temperature goes up.2.The piston doesn't move in and out.3.Heat flows out.4. Amount of heat evolved is +285 kj/mol
Explanation:
The temperature in the water bath will rise because heat being evolved is absorbed it.Based on principle of constant pressure, the piston doesn't move in and out.Since the reaction is a combination reaction, heat will be evolved.
