The molecule cyanazine, once used as an herbicide, has now been phased out by the EPA because of its significant human toxicity. Add lone pairs, as needed, to the structure of cyanazine. Indicate the hybridization of the specified atoms. Be sure to consider any lone pairs you added to the structure. The structure of cyanazine has 5 atoms highlighted. Atom 1 is an N atom bonded to 2 C atoms and 1 H atom through single bonds. Atom 2 is an N atom bonded to one C atom through a single bond and one C atom through a double bond. Atom 3 is a C atom bonded to one C l atom and one N atom through a single bond and one N atom through a double bond. Atom 4 is a C atom that is bonded to three C atoms and one N atom through single bonds. Atom 5 is a C atom that is bonded to one C atom through a single bond and one N atom through a triple bond. What is the hybridization of atom 1

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
