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.
Answer:

What is the difference between the two numbers? That is your answer
Answer:
there is no chance of any defects. 2) The position of isotopes becomes clarified in modern periodic table. That is the main two reasons as to why modern periodic table is less defective than Mendeeleev's periodic table.
Explanation:
Reason 1:- It is based on atomic number.
Reason 2:-Problem regarding Position of isotopes is resolved.
Reason 3:-Problem of position of Cobalt and Nickel is resolved whigh were placed wrongly in mandeelev periodic table.
Reason 4:-Blank spaces which were there in mandeelev periodic table are no more vacant now.
