Be sure to answer all parts. Be sure to report your answer to the correct number of significant figures. Calculate ΔG o and KP for the following processes at 25°C: (a) H2(g) + Br2(l) ⇌ 2HBr(g) ΔG o = kJ/mol KP = × 10 (Enter your answer in scientific notation.) (b) 1 2 H2(g) + 1 2 Br2(l) ⇌ HBr(g) ΔG o = kJ/mol KP = × 10 (Enter your answer in scientific notation.)

Which of the following statements is false regarding aromaticity? a. the compound must be cyclic b. the compound must be fully conjugated c. the compound must be planar d. the number of electrons in the pi system must satisfy the hückel 4n+2 rule e. the compound must have a neutral charge

The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is called a

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
