how many grams of the excess reactant are left over according to the reaction below given that you start with 10.0 g of al and 19.0 grams of o2?

divide 10.0g by each reactant's respective molar mass then divide that number by its coefficient in the balanced reaction. the smaller of the two numbers indicates the limiting reactant - it’s Al

hey your not cool]      

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
