Consider the hydrocarbon below. 2 carbons are double-bonded to each other; the pair are single bonded to h above left, above rig
1 answer:
Answer:
Explanation:
As the above statement says two carbon atoms are bonded to each other with double bond, the suffix used for double bond is -ene & the prefix for two carbon atoms is eth- & it says four Hydrogen atoms are attached to carbons, 2 Hydrogens to each carbon above & below.
When we draw the structural formula it comes out that the molecule is ethene.

Answer : The initial temperature of system 2 is,
Explanation :
In this problem we assumed that the total energy of the combined systems remains constant.
The mass remains same.
where,
= heat capacity of system 1 = 19.9 J/mole.K
= heat capacity of system 2 = 28.2 J/mole.K
= final temperature of system =
= initial temperature of system 1 =
= initial temperature of system 2 = ?
Now put all the given values in the above formula, we get
Therefore, the initial temperature of system 2 is,
