When balancing nuclear reactions:
A) there must be a net increase in charge
B) there must be a net decrease in charge
C) there must be no net change in charge
D) depends on the reaction
C. While balancing a nuclear reaction there must be NO NET CHANGE in chargre.
Overall charge must balance. Overall charge of reactants must be equal to products.
When balancing nuclear reactions: A) there must be a net increase in charge B) there must...
When balancing redox reactions using the half-reaction method, several conditions apply. Check all the REQUIRED conditions. When combining half-reactions, you must make sure the total number of electrons in each half cancels out. Oxidizing agents gain electrons. Electrons are reactants in the reduction half-reaction The number of electrons transferred by a reducing agent can be found by counting oxidation numbers. For polyatomic ions, the oxidation number of the central atom is the same as the charge. The total charges of...
In balancing redox reactions using the half reaction method, what is added to balance charge? positrons neutrons electrons protons
1. Declaring a dividend will: A. Increase net income. B. Increase the net worth of a company. C. Not change net income. D. Decrease net income. 2. 2. The concept of adequate disclosure: A. Does not apply to events occurring after the balance sheet date. B. Grants users of the financial statements access to a company's accounting records. C. Specifies which accounting methods must be used in a company's financial statements. D. Demands a "good faith effort" by management.
6) When balancing oxidation–reduction reactions in acidic solution by the half-reaction method the addition of H2O is required to balance the Select one: a. O2 b. OH– c. O d. H2O e. none of these
2. Consider the reactions 1 and 2 shown below. Indicate how the reaction rate for each of the reactions will change your options are: increase, decrease, does NOT change) when the following modifications to the reactions and conditions are introduced: reaction 1 reaction 2 Br CH30 Na CH3OH CH OH as solvent CH3OH is also solvent A. The reaction temperature for both reactions is increased. B. The concentration of the reagent shown above the arrow is increased. C. The concentration...
Part IV: Balancing Redox Reactions in Acidic and Basic Solution General rules for balancing redox reactions in acidic or basic solution: 1. Divide the redox reaction into two half-reactions. One that contains the element that gets Oxidized and one that contains the element that gets reduced. 2. Focusing on one half-reaction at a time, balance all non-H and non-0 atoms. 3. Balance the O atoms by adding water molecules to the side with too few oxygens 4. Balance the H...
oart A and B please ission Reactions In a nuclear fission reaction a heavy nucleus divides to form smaller nuclei and one or more neutrons. Many nuclei can undergo fission, but the fission reactions of uranium-235 and plutonium-239 are the principal ones that generate energy in nuclear power plants. This problem deals with balancing the fission reaction of the uranium-235 isotope as it undergoes bombardment from a neutron 14 of 36 > Review Constants 1 Periodic Table When a U...
Completing and Balancing Neutralization Reactions 10 of 18 For example, if you have a cation with a 1+ charge and an anion with a 2-charge, you will need two cations to balance the charge: I(1+ charge on cation)(2)]+[(2-charge on anion)(1)) = (+2) + (-2) = 0 Complete the following statements regarding the number of cations and anions present in the various ionic compounds. Match the numbers to the appropriate blanks in the sentences below. Make certain each sentence is complete...
