The water level in a graduated cylinder initially at 221 rises to 271 after a piece of lead is submerged. What is the mass in grams of the lead?
What exactly is an alkane and alkene? What is an ester?? does it relate to anything above?
the order of the reaction was n=0 and the value of the rate constant was 3.41*10^-3 M s^-1. I could find the order of reaction and the value of the rate constant but I am clueless about how to find the rate of reaction when [A]=0.15M.
Did an experiment where we extracted the caffeine in 1 bag of tea. We added the bag of tea leaves to the solution where the sodium carbonate solution. Explain what the purpose of adding the sodium carbonate was.
The principal quantum number, n, describes the energy level of a particular orbital as a function of the distance from the center of the nucleus. Additional quantum numbers exist to quantify the other characteristics of the electron
