chapter 4 types of chemical reactions and solution

... a. Volumes are always estimated to one position past the marked volume increments. The estimated volume of the first beaker is 32.7 mL, the estimated volume of the middle beaker is 33 mL, and the estimated volume in the last beaker is 32.73 mL. b. Yes, all volumes could be identical to each other be ...

... The best way to identify a redox reaction is to assign oxidation states to all elements in the reaction. If elements show a change in oxidation states when going from reactants to products, then the reaction is a redox reaction. No change in oxidation states indicates the reaction is not a redox rea ...

... molar mass is larger. Balance C: The element on the left (orange) has the higher molar mass because 5 orange balls are heavier than 5 purple balls. Since the orange ball is heavier, its atomic mass is larger, and therefore its molar mass is larger. Balance D: The element on the left (gray) has the ...

Chapter 4 MATERIAL BALANCES AND APPLICATIONS

... Material balances are nothing more than the application of the law of conservation of mass, which states that mass can neither be created nor destroyed. Thus, you cannot, for example, specify an input to a reactor of one ton of naphtha and an output of two tons of gasoline or gases or anything else. ...

... Avogadro’s number is used to change the number of moles to formula units. Each formula unit has two phosphate ions, so the total number of phosphate ions is two times the number of formula units. Solution: a) The formula of calcium phosphate is Ca 3 (PO 4 ) 2 . The molar mass, M, is the sum of the a ...
