☆☆☆☆☆16.0 lbs = 7,257 g of O2
Oxygen exists in the gas form as 02
7,257g O2 * 1 mol O2/ 32 g * 2 mol O / 1 mol O2 * 6.022x10^23 atoms/mol
= 2.73E26 atoms of O
A+B ➝AB
it tells which compounds will dissolve in water
Percentage composition= (mass of the element/mass of the molecule)*100
The fraction of the molecule's mass that comes from the element's mass
It compares how reactive the metals are
It predicts if one metal will replace another metal in a compound
62
Metals higher in the series will replace metal ions in solution that are lower in the series
The correct answer is: C5H12 + 8O2 5CO2 + 6H2O.
A combustion reaction
