The signs of a chemical reaction are bubbles, heat an magnesium disappearing.
Answer:
Explanation:This question is simply asking you to describe the following equations:
E = hv
v = c/L
E = hc/L
where E is the energy, h is Planck's constant, v is the frequency, c is the speed of light and L is the wavelength.
By looking at the equations you should be able to tell what the relationships between energy, frequency and wavelength are. If you are having difficulty describing them, then create a table with actual values and see what happens to the energy as you increase or decrease the frequency and/or wavelength.
The moon orbits the earth in the same direction as the earth, like if you had a ball on a string and you started spinning, the ball would spin the same direction.<span />

The organism shown above belongs to "the animal kingdom".
<u>Answer:</u> Option C
<u>Explanation:</u>
The biological classification's hierarchy involves eight important taxonomic ranks. They are written below in decreasing order: Life > Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species.
The U.S and Canada have historically used a six-kingdom scheme in their traditional textbook, such as Plantae, Animalia, Protista, Fungi, Archaea / Archaebacteria, and Bacteria / Eubacteria. The given image depicts snake which come under "Animalia Kingdom", carnivorous reptiles to suborder Serpentes.
