Schrodinger's major contribution to quantum theory was to
a. solve the wave equation for electron waves within the hydrogen atom confirming that the electron can only exist in discrete energy levels in that atom.
b. explain that energy is emitted from atoms in high temperature solids as discrete packets of electromagnetic radiation later called "photons"
c. prove that light with frequency above a certain threshold value can cause electrons to be released from certain metals
d. propose that electrons in atoms may exhibit wave-like behavior under some conditions
e. propose that for nanoscale particles like electrons, it is not possible to determine their energy or momentum and their positon simultaneously

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

explanation:

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
