How can the octet rule be used to explain why one magnesium (mg) atom would bond with one oxygen (o) atom?

a. oxygen has six valence electrons; it needs to lose these electrons to reach the octet rule with a full second energy orbital. magnesium has two valance electrons; it would prefer to gain six valence electrons to reach the octet rule of a full second energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.

b. magnesium has six valence electrons; it needs to gain two electrons to reach the octet rule with a full second energy orbital. oxygen has two valance electrons; it would prefer to lose both valence electrons to reach the octet rule of a full second energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.

c. oxygen has one valence electron; it needs to gain two electrons to reach the octet rule with a full first energy orbital. magnesium has one valance electron; it would prefer to lose its valence electron to reach the octet rule of a full first energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.

d. oxygen has six valence electrons; it needs to gain two electrons to reach the octet rule with a full second energy orbital. magnesium has two valance electrons; it would prefer to lose both valence electrons to reach the octet rule of a full second energy orbital. therefore, one magnesium atom can satisfy the needs of the oxygen atom to form an ionic bond.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
