When balancing the equation you need to know how many moles reacted and how many were formed.To balance this equation we require 1 moles of C2H4, 3moles of O2 to form 2 moles CO2 and 2 moles H2o
therefore the equation is represented as
C2H4+3O2 ->2CO2+2H2O
Answer : The new pressure of the gas will be, 468.66 atm
Explanation :
Boyle's Law : This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
or,
where,
= initial pressure of the gas = 74 atm
= final pressure of the gas = ?
= initial volume of the gas = 190 ml
= final volume of the gas = 30 ml
Now we put all the given values in the above formula, we get the final or new pressure of the gas.
Therefore, the new pressure of the gas will be, 468.66 atm
Answer:Answer: Mendeleev's table of elements was better accepted than those of other scientists at the time because it predicted correctly the properties of elements that had not yet been discovered. Moseley went a step further in suggesting that the elements be arranged according to atomic number
Explanation:
Odd, unusual, or unexpected.
