A wine-dispensing system uses argon canisters to pressurize and preserve wine in the bottle. An argon canister for the system has a volume of 29.1mL and contains 36.6g of argon.Assuming ideal gas behavior
If the titrant has a molarity of 0.2750 M and there are 25.00 mL of analyte present, what is the molarity of the analyte?
Use Hess' Law to show how the titration of acetic acid with sodium hydroxide can be expressed as the combination of two reactions: the acetic acid reacting with water, and the sodium hydroxide reacting with hydronium ion.
what is the molarity of the base? Show clearly all strps of calculation please and a generalized chemical equation
Water expands on freezing. Since water is the principle ingredient in soft drinks when the soft drink freezes it will rupture the can.
