Answer:
[H₃O⁺] → 0.063 M
Explanation:
To determine the pH, our formula is:
- log [H₃O⁺]
To determine the [H⁺] we have to apply the inverse function
10^-pH = [H₃O⁺]
10⁻¹'²⁰ = [H₃O⁺] → 0.063 M
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
Because the tree might get struck by lightning and the tree will catch on fire leaving you to get burned
Answer: The correct option is A.
Explanation: To calculate the volume at the end , we use Charles's Law, which states that the volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
or
Putting all the values in above equation, we get
Hence, the correct option is A.
The answer to this is solved through stochiometry: the answer is this: 0.0833mol
