☆☆☆☆☆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
9.979 kg
Algebraic Steps / Dimensional Analysis Formula 22 lb*1 kg
2.2046 lb=9.97903214 kg
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
air and fuel intake, compression and ignition, combustion and expansion, exhaust
It compares how reactive the metals are
It predicts if one metal will replace another metal in a compound
62
The correct answer is: C5H12 + 8O2 5CO2 + 6H2O.
C3H8 + 5O2 = 3CO2 + 4H2O, so the coefficient for O2 is 5
The reactants will have one Na, one Cl, one O, and two H atoms
The engine will run inefficiently.
