Which test tube (1 or 2) initially had the most solid precipitate? Why was there more ppt. in this test tube? (Hint: Which solution initially contains more free floating C2O42- ions? ...K2C2O4 or H2C2O4?)

What four properties do all waves have in common

What conclusion can you draw from this experiment about the components of the black ink?

Calculate the standard enthalpy of formation of liquid methanol, ch3oh(l), using the following information: c(graphite) + o2 latex: \longrightarrow ⟶ co2(g) latex: \delta δ h° = –393.5 kj/mol h2(g) + o2 latex: \longrightarrow ⟶ h2o(l) latex: \delta δ h° = –285.8 kj/mol ch3oh(l) + o2(g) latex: \longrightarrow ⟶ co2(g) + 2h2o(l) latex: \delta δ h° = –726.4 kj/mol
