How many grams of a 1000.0g sample would remain after 24 hours?The rest of the questions are from the entire book (to help you start reviewing) (you still have to do them!!!)3) A chunk of copper weighing 352.4g has 4212 calories of heat added to it. By how many oC did the temperature change?The specific heat for copper is 0.108 cal/(g * oC). (Remember significant figures)4) Fill in the blanks on the following table.CompoundName_______________________________________nickel (III) sulfite_______________________________________perchloric acidPCl5_______________________________________Ti(CO3)2_______________________________________5) Write the electron configuration for a Niobium (Nb) atom. 6) A compound is found to be 54.52% carbon 9.17% hydrogen and 36.31% oxygen.
