Using a displacement reaction we can put a more reactive metal into cobalt sulphate of where the more reactive metal (such as zinc, aluminium or magnesium) will displace cobalt out of the solution leaving the elemental form of cobalt metal deposit left in a solution of (whatever metal you chose) sulphate.

The speed of the sound in air at room temperature is 343 m/s. Calculate this speed in miles per hour.
hjlf

Convert metres to feet:

343m*3.28f = 1,125.04ft/s

There are 3600 (60 seconds * 60 minutes) seconds in an hour. Therefore, use this number to convert to an hour.

1,125.04ft*3600s = 4,050,144 ft/h

Now, since you asked for miles, convert to miles (5280 ft in a mile):

4,050,144ft/5,280m = 767.072mph

That is your answer! Hope I helped. :)

Which statement best describes the way a catalyst works?
bogdanovich [222]

Answer: E. It decreases the value of Eact.

Explanation:

Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products.

The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
