It's not unusual for students who see this demonstration to claim that the "red stuff" is rust (meaning the compound iron III oxide). Brainstorm some empirical data (information that you could collect in the lab) that would prove or disprove the claim that the "red stuff" is rust.

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
