Match the terms to the correct descriptions. question 1 options: this type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band this is energy that is transferred by the movement of electrons through a conductor: the electrons create a current. this can be either kinetic or potential and has to do with the energy of position and motion of an object this type of energy is often found in things like batteries or food this has to do with the speed of an object and how much mass it has; basically how the object is moving this is radiant energy from the sun; it's the only kind of energy we can see with our eyes this type of energy travels through vibrations on waves this type of energy can be transferred in three different ways: 1) direction contact through collisions (also called conduction), 2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection), and 3) by waves traveling with or without a medium (also called radiation) this is the energy found in the nucleus of an atom this is the term used when energy changes from one form to another 1. mechanical energy 2. kinetic energy 3. potential energy 4. electrical energy 5. light energy 6. thermal energy 7. sound energy 8. chemical energy 9. nuclear energy 10. energy conversions

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
