6. A chemist adds an indicator to a basic solution. The indicator is yellow in a basic solution, but turns blue in an acidic solution. The chemist wants to determine when a basic solution becomes acidic as he adds measured amounts of a weak acid to the solution. Which of the following is an observation that will prove useful? (2.5 Points) the indicator measured amounts of a weak acid a color change a change in the chemical composition of the solution

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
