When 1.06 g of liquid PC13 at 11.8 C is added to a solution of water at in a coffee cup calorimeter, the temperature of the solution increases to 38.1C. If the heat
capacity of the solution and calorimeter is 421.7 J/C, calculate the molar heat of the
PC13. Answer to 0 decimal places in kJ/mol.

Hey can you me with this i really need y’all

The bohr model of the atom explained why emission spectra are discrete. it could also be used to explain the photoelectric effect. which is a correct explanation of the photoelectric effect according to the model?

Tinererining 01: 57: 44 which statement correcte describes the actual veld and the theoretical yield of a reaction? textual vec is calculated to the reactant amounts but the theoretical yeld must be measured for each instance of a the actual vec is calculated from the amount of the limiting reactant and the theoretical yield is calculated from the 发公主 the actual weld depends on the reaction centers, but the theoretical yield and only with reactant amounts the actual vele represents the maximum weld possible and the theoretical yield assumes perfect reaction conditions save and ext e அட
