The total pressure in a 11.7 L car tire is 44 psi at 11 degrees Celsius. How much does the pressure in the tire rise if its temperature increases to 37 degrees Celsius and the volume remains at 11.7 Liters?

If 24.6 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 301 Kelvin and 1.01 atmospheres? Show all of the work used to solve this problem. 2Li (s) + 2H2O (l) yields 2LiOH (aq) + H2 (g)

How the law of conservation of mass could be useful for investigating chemical changes

A covalent chemical bond is one in which outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms. protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.
