Suppose you inflate the tires on your car to 35 pounds per square inch (psi) on a warm fall day in Minnesota (27.0°C, or about 80°F). The next day the temperature plunges to -10.0°C (about 14°F). What is the resulting pressure in your tires? Assume that the volume of the tires remains the same.

a. 30.7 psi
b. 35.0 psi
c. 37.6 psi
d. 42.2 psi
e. 26.8 psi

part C

Explanation:

Suppose you inflate the tires on your car to 35 pounds per square inch (psi) on a warm fall day in Minnesota (27.0°C, or about 80°F). The next day the temperature plunges to -10.0°C (about 14°F). What is the resulting pressure in your tires? Assume that the volume of the tires remains the same.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
