i need help on both A and B please < Week 2 Assignment: Nuclear Chemistry and Chemical Equilibrium Calculating Equilibrium Constants The equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. For a gaseous reaction with the general form aA + bB =cC+ dD the K, and Kp expressions are given by K = ( CD [A]"B" K np _(Pc)(Pb) (PA)"(PB) The subscript c or...
please help with all pre-lab Dynamic Equilibrium Simulation with Pennies 1 of 11 on Equilibrium is a state where there are no observable changes over time. Equilibrium is achieved when the rate of the forward reaction equals the rate of the reverse reaction. R =P In this activity, we will simulate a reversible reaction where R = P: the reactant molecules (R) are pennies, which react and are transferred from the side to the P side, while the product molecules...
Need help, numbers 3-6 please show work. and fill out table of chemicals for all chemical used. calculate mmol in the table as well show work please and each of these must be listed in its own row. There are 10 column headings: IUPAC name OR common name, structure, CAS number (Chemical Abstract Service number) molecular mass, melting point (if applicable), boiling point (if applicable), solubility (in water, if applicable), density, amounts to be used in the experiment, and the...
