In the flame test, a solution containing an ionic compound is heated. an observation is made concerning the color of the heated solution.(a) color in a substance arises from which two closely related processes? frequency and wavelengthmonochromatic and polychromatic ground state and excited stateabsorption and emission(b) what process is occurring when the solution is heated? an electron emits energy and it makes a transition to a higher energy orbital. an electron absorbs energy and it makes a transition to a lower energy orbital. an electron emits energy and it makes a transition to a lower energy orbital. an electron absorbs energy and it makes a transition to a higher energy orbital.(c) what process is occurring when the color appears in the flame? an electron emits energy and it makes a transition to a higher energy orbital. an electron absorbs energy and it makes a transition to a lower energy orbital. an electron emits energy and it makes a transition to a lower energy orbital. an electron absorbs energy and it makes a transition to a higher energy orbital.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
