18.2 g of a basic solution was mixed with 31.1 g of an acidic solution in a calorimeter with a calorimeter constant of 76.8 J K–1 with all substances initially at 27.8 °C. The resulting solution was observed to be at a temperature of 54.2 °C and have a heat capacity of 4.59 J g–1 K–1.
Determine q for the mixing process.

Which scenario is most similar to the type of collision that gas particles have according to kinetic molecular theory

Who discovered a pattern to the elements in 1869?

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
