Like the diagram we can see the the products of reaction are obtained with a amount of heat under the heat of reactants... so the reaction is exothermic and the Ea = E* - Eproducts = 100 - 40 = 60 kJ
Pentane consist of 5 carbon atom and have the shape of a pentagon...
one C atom is bonded to 2 other C atom and in addition 2 other H atom
so one C atom will be bonded to 4 other atom in total and hence sharing all its available electons
Hey there:
density = 11.3 g/cm³
mass = 15,1 g
Therefore:
D = m / V
11.3 = 15.1 / V
V = 15.1 / 11.3
V = 1.336 cm³
In my opinion the answer is D
