The dipole moment (μ) of hbr (a polar covalent molecule) is 0.797d (debye), and its percent ionic character is 11.8 % . estimate the bond length of the h−br bond in picometers. note that1 d=3.34×10−30 c⋅m andin a bond with 100% ionic character, q=1.6×10−19
c.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
