How does thermal energy transfer when a room is heated by a furnace? a)hot air is absorbed by the objects in the room; cold air expands and rises. b) hot air is circulated through the room; the hot air rises, and cold air falls. c) hot air makes direct physical contact with the objects in the room and rises. d) hot air is transmitted by electromagnetic waves; the hot air rises and falls.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

Under which circumstances are kp and kc equal for the reaction aa(g)+bb(g)⇌cc(g)+dd(g)?

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
