An alloy of al and cu was treated with aq hcl .the aluminium dissloved according to the reaction al+3h =al+3/2h2,but the cu remained as the pure metal .a 0.350 gm sample of the alloy gave 415cc of h2 measured at 273.1 °k and 1 atm pressure .what is the wt percentage of the al in the alloy

What are the major products produced in the combustion of c10h22 under the following conditions? write balanced chemical equations for each. a. an excess of oxygen b. a slightly limited oxygen supply c. a very limited supply of oxygen d. the compound is burned in air

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

What forms when chemical reactions combine pollution with sunlight?
