Write a balanced chemical reaction for the reduction of dissolved copper ion by Zn (s) to copper metal
Imagine you want to determine the binding constant for a reaction. You know you will need to generate data to calculate the binding constant.
A sample of water 53 g with a temperature of thirty six degree celsius is combined to 250 grams of H 2 O at 91 degree Celsius in an insulated container. Determine the final temperature after thermal equilibrium is reached?
high boiling point are obtained now you need to identify the limiting reagent and compute the percent yield of nitrobenzene
Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written
Calculate the molality of a 20.0 per cent by weight aqueous solution of NH4Cl. (Molecular weight: NH4Cl = 53.5) (b) If this NH4Cl solution is assumed to be ideal and is completely dissociated into ions
Calculate the concentrations of all species in a 0.370 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid
a solution of 8.32g of paba in 150g of chloroform boiled at 62.62C. what is the molecular mass of paba?
Calculate the values for Z1 and Z11 for mercury (Hg) vapor at 40 degrees C at P = 0.10 atm. How does this quantity depend on pressure
