Copper is an brown-orange color which it's atomic number is 29. With high thermal and electricity conductivity with it's smooth surface.
It would be 4:15 . Just add 3:30 plus 45 too get the answer
Answer:
38 : 25
Explanation:
First thing's first, we have to confirm if the reaction is indeed balanced.
The equation of the reaction is given as;
C25H52 + 38 O2 → 25 CO2 + 26 H2O
From the reaction, 38 moles of O2 produces 25 moles of CO2
The ratio is given as;
38 : 25
