Which of the following pairs would most accurately produce a 10 Which of the following pairs of sample compounds would most accurately produce a 10% HNO3 acid?
A. 10 g HNO3 and 90 g H2O B. 10 g HNO3 and 100 g H2O C. 10 ml HNO3 and 90 ml H2O D. 10 ml HNO3 and 100 ml H2O E. 10 g HNO3 and 100 ml H2O
Any one got explanations on this...??
What would be the percentage yield if 11 What would be the percentage yield if 11.85 g of Na2S2O3 were obtained from a reaction mixture containing 12.60 g of Na2SO3 and 5.00 g of S? Na2SO3 + S à Na2S2O3
A. 55% B. 60% C. 65% D. 70% E. 75%please explain the working procedure..
also.. What do you all know about Kinetic Energy ?
Any clue on what is thermodynamically favorable and non favorable? i believe there is question like that in the destroyer somewhere.. to tired to look up which one.
Also how do you all remember the difference between the galvanic /electrolytic cell.. on avhiever its asking for A Daniel CELL??? what is that.. Ok lots of questions..help me ou thanks guys
