The wavelength of green light is 5.5X 10^-7 meters. Please calculate the energy that this light gives off using the speed of light equation to find the frequency which is in the question above, as well as the energy equation, E-h*1(
hPlanck's constant 6,63*10^-34 J*s). Make sure your final answer is in scientific notation using the
carrot to signify an exponent​

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

answersilicon (si); oxygen (o);

the objects have the same charge.
