Explanation:
The balanced chemical equation of the reaction is:

From the balanced chemical equation,
1 mole of propane forms ------ 3 mol. of
gas.
The molar mass of propane is 44.1 g/mol.
One mole of any gas at STP occupies --- 22.4 L.
Hence, 44 g of propane forms (3x22.4 L=) 67.2 L of CO2 gas at STP.
Answer:
Thus, 67.2 L of CO2 is formed at STP.
Answer:
Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation.
On complete conversion (100% yield) 9.75 g of ethyl butyrate will be produced. Below is the solution.....
