To 100.0 mL of a solution that contains 0.120 M Cr(NO3)2 and 0.500 M HNO3 is added 20.0 mL of 0.250 M K2Cr2O7. The dichromate and chromium (II) ions react to give chromium (III) ions. (a) Write a balanced net ionic equation for the reaction. (b) Calculate the concentrations of all ions in the solution after reaction.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

the answer is barium and copper bromide

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
