Lithium metal reacts with molecular oxygen gas to form lithium oxide. A closed container of volume 8.00 x 103 mL contains oxygen gas at 99.8 °C and 2.12 x 103 Torr. Then 11.5 g of solid lithium is introduced, and the reaction goes to completion. What is the final pressure (in Torr) if the temperature rises to 168.1 °C?

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

The higher the temperature, the increased rate constant for a reaction.(positive linear association)

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.

Is a renewable energy source that's highly environmentally friendly.hope this is what you're looking for. have a great day! : d
