How many moles of PCl5 can be produced from 53.0 g of Cl2 (and excess P4)?
elena55 [62]

Answer:

0.299 moles of PCl5

Explanation:

First form an equation based of given information: P4 + Cl2= 4PCl5

Next balance it: P4 + 10Cl2 = 4PCl5

Take your given value (53.0g of Cl2) and divide it by its molar mass to get moles of Cl2: 53.0g/70.906g = 0.747 moles Cl2

Then, multiply by the molar ratio (10Cl2 to 4PCl5): (0.747 x 4 mol PCl5)/10 mol Cl2 = 0.299 moles PCl5

It is possible to make a model of a fission chain reaction with mousetraps and table tennis balls, with the balls placed on an a
konstantin123 [22]

Answer:

The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split

Explanation:

Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.

It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will  be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.

It can also be modeled as such:
