Give the following details about HBr total number of electrons: [electrons] name: [name] number of sigma bonds: [sigma] number of pi bonds: [pi]

The following graph shows the progression of a reaction between molecular hydrogen (H2) and molecular (I2) to produce hydrogen iodide (HI). Referencing the graph, answer the next seven questions.   See the description for details “This image depicts a graph showing the progression of a chemical reaction between molecular hydrogen (H2) and molecular iodine (I2) to form hydrogen iodide (HI). The red line represents the concentration of H2(reactant). The black line represents the concentration of I2 (reactant). The red dashed line represents the concentration of HI (product).The vertical line marked “”A”” is used as a reference for further questions regarding the concentration progression over time.”

H2S molecular shape: [shape] hybridization of the central atom [hybridization] common name or IUPAC name: [name] number of sigma bonds: [sigma] number of pi bonds: [pi]

There are three types of molecular motion that gas molecules possess. Which of the following types of molecular motion do gas molecules possess but liquids and solids do not?

Answer the following questions using the simplified solubility rules below: Cations that are always soluble: Compounds of group 1 cations (Na+, K+, etc.) and ammonium (NH4+) are always soluble. Anions that are always soluble: Nitrate (NO3−) anions are always soluble. Halides: Compounds of the halides (Cl−, Br−, I−) are soluble except for silver(I) (Ag+) and lead(II) (Pb2+). Sulfate: Compounds of sulfate (SO4 2−) are soluble except for group 2 cations (Ca2+, Sr2+, Ba2+) and lead(II) (Pb2+). Everything else: Most other compounds not listed as soluble in rules 1–4 are assumed to be insoluble.
