A student conducted a titration to determine the concentration of a mystery bottle of sulfuric acid (H2SO4) found in the lab with no label. The balanced equation for the reaction is below: 2 NaOH + H2SO4 → Na2SO4 + 2 H2O

a) If 400.0 mL of 1.7 M NaOH was used in the reaction, how many moles of H2SO4 were used in the reaction?
b) If there were 100.0 mL of the H2SO4 solution at the beginning of the reaction, what was the molarity of the H2SO4 solution?

Agas is contained in a thick walled balloon when the pressure changes from 1.21 atm to 2.52 the volume changes from 3.75 l to 1.72 l and the temperature change from 293k to blank k

How many moles of cu are needed to react with 5.8 moles of agno3? cu + 2 agno3 → cu(no3)2 + 2 ag

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.
