What is the balance chemical equation for the reaction of CuSO4 + NAOH and what is the reaction classification.
at equilibrium, it was found that the concentrations were: .0584M for H2, .0195M for N2 and .430M for NH3. What was the initial concentration of ammonia
Assuming that prior experiments have shown the single-step extraction removes only 71.0 % of the ethanol, what is the mass of ethanol in your original unknown?
The number of resonance structures (not involving d orbitals) required to correctly describe the bonding in the linear ion Nâˆ'3 is:
What is the vapor pressure at 75 degrees celcius of an aqueous solution prepared by the addition of 52.9 g of urea CO(NH2)2 to 178 g of water?
Orange juice is an aqueous solution that derives much of it's acidity from citric acid. There are variations in the acidity of each brand depending on many factors. Use the data below from an acid-base titration
A 5 m^3 tank comtains methane. the initial temperature and pressure are P=1bar T=18 degrees C. calculate the P following the each of the successive steps using the ideal gas law
The molality of the solution is determined to be .0480m. What is the molar mass of the substance?
You are looking for a range so you need to find the Ksp of the first test tube that did not have precipitate and the last test tube that had precipitate.
For the first order decomposition of acetone at 650 K, the concentration of acetone was 0.350 M after 25.0 min and 0.170 M after 40.0 min.
A buffer solution with a pH reading a 8.50 was prepared by mixing 0.25 mole acid (HA) and 0.05 mile NaOH in 500.0mL DI water. How much more gram of NaOH you should add to this solution in order to have the highest buffer capacity of this solution
