Answer:
Explanation:
1 x 10²³ molecules of methane
6.02 x 10²³ molecules of methane = 1 mole of methane
10²³ molecules of methane = 1 / 6.02 moles of methane
= .166 moles .
Answer:
The correct answer is option B.
Explanation:
When we increase number of molecules of reactant frequency of the molecular collision increases due to which effective collision between reactant molecules to form a product also increases, With this overall rate of the reaction increases.
Where as:
When we increase the temperature of the reactant molecules increase in average kinetic energy of the molecules is observed.
When we increase the activation energy of the reaction rate of the reaction slows down,
Answer: 75.7 % yield
Explanation:
The balanced chemical equation is:
According to stoichiometry :
68.2 g of 
will require = 64 g of 
Thus 7.5 g of will require = 
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 68.2 g of give = 96 g of
Thus 7.5 g of give =
of 
% yield=
Thus 75.7 % yield is there.
