A cylinder is filled with 10.0 L of gas and a piston is put into it. The initial pressure of the gas is measured to be 90.1 kPa .The piston is now pulled up, expanding the gas, until the gas has a final volume of 49.0 L. Calculate the final pressure of the gas. Round your answer to 3 significant digits.

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
