<u>Answer</u>:
Electric evaporator has been used to clean up the Chernobyl and 3 mile island accident.
<u>Explanation</u>:
About 14 years back, there was a puff of radioactive steam from the evaporator used in the "Three-mile island" nuclear plant. It took two years for the electric evaporator to clean up the 2.2 million gallons of water that have been destroyed because of the nuclear power plant accident.
The steam that came out of the electric evaporator carried a radioactive form of hydrogen and tritium with itself. Cost of clean up was $1 billion.
Answer:
heat energy are absorbed by water molecules and it is used to change the molecules from liquid to gas? if thats what your asking.
Explanation:
Answer:
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. You might recognize its chemical formula, H2O2, as being similar to that of water (H2O). The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.
Answer=1
Potassium Sulfide= K2S (two metals, one non metal)
Sodium Oxide=Na2O (two metals. one nonmetal)
Sodium Chloride=NaCl (one metal, one nonmetal)
Magnesium Oxide=MgO (one metal, one nonmetal)
Magnesium Chloride=MgCl2 (one metal, two nonmetals)
Answer: The energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
Explanation:
Given: n = 2
The relation between energy and 
orbit of an atom is as follows.
Substitute the values into above formula as follows.
The negative sign indicates that energy is being released.
Thus, we can conclude that the energy of an electron in the n = 2 level of a hydrogen atom is 3.40 eV.
