A mixture of hydrogen and xenon gases, in a 5.77 L flask at 84 °C, contains 0.433 grams of hydrogen and 19.4 grams of xenon. The partial pressure of xenon in the flask is atm and the total pressure in the flask is atm.

A mixture of nitrogen and oxygen gases is maintained in a 8.23 L flask at a pressure of 1.46atm and a temperature of 56 °C. If the gas mixture contains 6.54 grams of nitrogen, the number of grams of oxygen in the mixture is g.

The stopcock connecting a 4.26 L bulb containing xenon gas at a pressure of 7.79 atm, and a 4.85 L bulb containing hydrogen gas at a pressure of 4.65 atm, is opened and the gases are allowed to mix. Assuming that the temperature remains constant, the final pressure in the system is atm.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance

Which of these features are formed when hot groundwater is forced out through cracks in the earth's surface?
