Single and double replacement
MrMuchimi

Answer:

Explanation:

A single replacement or single displacement reaction is a reaction in which one substance replaces another.

            A  +   BC →   AC + B

The replacement of an ion in solution by a metal higher in the activity series is a special example of this reaction type.

The relative positions of the elements in the activity series provides the driving force for single displacement reactions.

A double replacement reaction is one in which there is an actual exchange of partners between reacting species. This reaction is more common between ionic substances;

              AB + CD → AC + BD

Such reactions are usually driven by;

  • formation of precipitation
  • formation of water and a gaseous product

A sample of gas has a pressure of 742 torr. What is the pressure in atmospheres?
ycow [4]

Answer:742 torr= approximately 0.976 atm

Explanation:

Since we know that one atm= 760 torr, we can compute the following calculation:

(742 torr/1)*(1atm/760torr)=0.976316 atm

Remember sig figs (3) to round it to 0.976 atm

\frac{742 torr}{1}*\frac{1 atm}{760 torr}=0.976316=0.976 atm

(torr cancels out and we're left with atm)

Hope this helps :)
