A sample of gas occupies 15.0 liters at a pressure of 2.00 atmospheres and a temperature of 300 K. If the pressure
is lowered to 1.00 atmosphere and the temperature is raised
to 400 K, the volume of the gas sample would be

How many moles of gas are present if p=11 atm, v=12l, t=185k?

According to the vsepr theory what is the shape of a molecule that has a central atom valence three other items with no lone pairs of electrons

Which statement explains why the bonds between non metals tend to be covalent? the bonds are found to be nondirectional they have large differences in electronegativity they have small differences in electronegativity they have ions that produce an electrostatic pull
