A. Put a stick or pencil through the center of each gear. Try putting them together, two at a time, by fitting the notches of one into the notches of the other. Use the small one to turn the big one. Use the big one to turn the medium one. Use the medium one to turn the big one and then the small one. b. Download and print the chart below, fill it by using your gears. Make a red mark on the rim of each of your gears. Fit Gear A into Gear B at the point at which the two red marks touch. Turn Gear A one full turn; how many turns does Gear B make? Is it fewer than Gear A or is it more than Gear A? Fill in the chart accordingly. For example, if for every turn that Gear A makes, Gear B turns 3 times, write “3” on the chart and fill in the ratio as 1:3. (The ratio is however many times the second gear turns in respect to one turn of the first gear.)

> 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.

b. is the answer hoped i        

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
