phosphorus burns in the limited supply of air to form phosphorus(iii)oxide, P4O6 and in unlimited supply of air to form phosphorus(v)oxide P4O10. If 3.3g of phosphorus(iii)oxide is formed what mass of oxygen from air is used

219 grams of iron (iii) oxide reacts with excess carbon according to the reaction equation shown below. fe2o3 + c → fe + co2 after a scientist performs the chemical reaction they find the actual yield of iron to be 57.4 grams. calculate the percent yield of this chemical reaction.

Non renewable resources like petroleum eventually

The three types is stress that act on earths rocks are compression, tension, and
