Answer:
Generally, the first ionisation energy increases along a period. But there are some exceptions one which is not an exception
The most of the pollutants (carbon monoxide, nitrogen monoxide and unburned hydrocarbons) are released from the car during the first one to two minutes after the car is started, and then decrease significantly after that, due to increasing the temperature which supply the system by heat that required to oxidize the released gases by increasing the rate of the chemical reaction.
Then, the correct answer is the temperature (B).
Answer:
B
Explanation:
Trust me I've had problems like these
3CH4 refers to three molecules of a
compound and C3H12 refers to only one
molecule of a compound.
3CH4 and C3H12 are actually different
molecules though they contain the same
number and types of atoms. Recall that both
of them are hydrocarbons hence they
contain only hydrogen and carbon.
3CH4 refers to three molecules of methane
while C3H12 refers to one molecule of
diphenyl methane. Hence 3CH4 refers to
three molecules of a compound and C3H12
refers to only one molecule of a compound.
