What is a reaction between a strong acid and a strong base is known as?
i need to know how each of these "Behaves", either an acid orbase and then write a reaction showing how it reacts withwater- i have noidea what i'm doing, or where to start... ='[-NaCN-HCL-HNO3-HC2H3O2-AlCl3-NH4Cl- How do i know if its acid or base and howit reacts in water???thankyou very much
A flask of Argon gas is connected to the left arm of a manometer. The Hg level is 76.1cm. The right arm of the manometer is open to the atmosphere and has a Hg levelof 63.9cm. The atmospheric pressure of the lab is 0.679 bar. What is the pressure (torr) of the gas sample?

How do you do back titrations to find the Molarity of Ascorbic Acid (C6H8O6)? There are three equations given: IO3^- +8I- --> 3I^- + 2H2O C6H8O3 + I3- --> C6H6O6+ 3I^- + 2H^+ I3- + 2S2O3^2- --> 3I^- + S4O6 ^2- How can you calculate the excess I3-? So that I can then calculate Ascorbic acid since its a 1:1 mole ratio. PLEASEHELP!!!
