2. What mass of CO2 will escape from the liquid champagne if the bottle is briefly opened and the partial pressure of CO2 is reduced to 1.0 atm? (Assume 1.0 L of liquid in the bottle).

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

Conservation efforts have been effective in "increasing the number of endangered species, reducing all the negative impacts of human activity, and preserving wildlife habitats".hope my answer has you : ) 

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
