An exergonic reaction proceeds with net release of free energy.
An endergonic reaction absorbs free energy
Explanation:
the energy that that is needed to break a bond is called the bond energy or dissciation energy
Answer:
4
Explanation:
Carbon configuration- 2,4
Valence electrons means the outershell electrons
That means valence electrons=4
In the combustion process using excess oxygen, each mole of methane results to 1 mole of co2 while ethane produces 2 moles of Co2. Under same conditions, these can be translated to volume. Hence the total volume absorbed is 10 cm3 + 20 cm3 = 30 cm3.
