Explanation:
Answer:
I think the answer is 138.11 gram
Explanation:
Answer:a) 11.34 g of ethane
can be formed
b)
is the limiting reagent
c) 3.44 g of the excess reagent remains after the reaction is complete
Explanation:
To calculate the moles :
1. 
2. 
According to stoichiometry :
1 mole of
require 1 mole of 
Thus 0.378 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
moles of
left = (2.10-0.378) = 1.72 moles
mass of
left=
According to stoichiometry :
As 1 mole of
give = 1 mole of 
Thus 0.378 moles of
give =
of 
Mass of 
Thus 11.34 g of ethane is formed.
Answer:

Explanation:
chemistry the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Science the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
