The pressure in car tires is often measured in pounds per square inch (lb/in.2), with the recommended pressure being in the range of 25 to 45 lb/in.2. suppose a tire has a pressure of 27.0 lb/in.2 . convert 27.0 lb/in.2 to its equivalent in atmospheres.

1.36 atm

Explanation:

First, we have to transform lb and in² into the International System of Units.

The equivalence between Pascal and atm is 101,325 Pa = 1 atm. Then,

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
