CEM 141 Exam 1 MSU Pollock11.3 g of NO - ANS-What is the maximum amount (in grams) of NO that would be produced
during this reaction?
525.7 g - ANS-What is the mass of two moles of Mg3(PO4)2?
All atom contain electrons. - ANS-Thomson discovered that the type of metal used for the
cathode did not affect the behavior of the cathode ray. What claim does this piece of evidence
support?
Atoms of Y interact to form covalent bonds. Covalent bonds are stronger than LDFs and require
more energy to break. - ANS-You are asked to compare the interaction between atoms of two
substances, X and Y. When you look at the graph showing how potential energy changes as the
distance between atoms changes, you notice that substance Y has a much deeper potential
energy well than X. From this information you can conclude-
C. 15.0 g O2
15/16 (O atomic mass) - ANS-Which of these contains the largest number of molecules?
A. 15.0 g Br2
B. 15.0 g Cl2
C. 15.0 g O2
D. They all have the same number.
During a collision energy will be transferred from the surrounding Xe atoms to the system of two
Xe atoms and the stable interaction will be overcome. - ANS-Consider the container of Xe
atoms where two Xe atoms of interest are interacting (the system) and are surrounded by other
Xe atoms in the system. The surrounding Xe atoms have more energy than the system. Which
direction would you predict the energy would be transferred and what would happen?
increase because of the repulsive force between like charges. - ANS-As two protons move
toward each other, the potential energy of the system will -
LDFs between the O2 molecules are overcome. - ANS-When oxygen boils -
No, there are not enough reactants to produce 25g of NO. - ANS-In the lab you mix together
10g of ammonia with 15g of oxygen to form nitric oxide and water. You are asked to produce
25g of nitric oxide (NO). Do you have enough starting materials to produce the desired amount
of NO and why?
No, there is more product than could possibly be formed and so there must be an impurity in it. -
ANS-Glucose reacts with oxygen to produce carbon dioxide and water. During this reaction ten
