Dr. bunsen has a problem—he stored a rack of six bottles filled with clear colorless liquids too close to a heat vent and the labels fell off of each of the bottles. he needs your in order to correctly identify each of the solutions. below is a list of the solutions:  pure di water  0.10 m agno3  0.20 m hcl  0.20 m hno3  0.20 m koh  0.50 m nahco3 we are provided with ph paper and phenolphthalein

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4

How does the principle of electromagnetism explain the interaction between earth’s magnetic field and the solar wind?

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 .
