although acids are corrosive to metals, you were able to pour these acids down the drain without hurting the pipes. Why?
Inorganic Chemistry
A balloon is inflated to a volume of 1.250 L with dry hydrogen gas, at 28.0 °C. The balloon is then
cooled, and its volume drops to 964 mL. If the pressure is unchanged, what is the hydrogen gas temperature (in °C) in the cooled balloon? Assume that no gas has been added or removed.
