Acid Rain is a result of chemical compounds, like sulfur dioxide and nitrogen oxide, are released into the air. These compounds rise high into the atmosphere and react with the different elements and compounds in the air, such as oxygen and water. This reaction forms acidic pollutants and eventually fall back to the ground as acid rain. This phenomenon is attributed to industrial waste; and it was especially common in the wake of the Industrialization Era of the United States.
Answer:
A. the iron atoms are gaining kinetic energy
Explanation:
when the iron melted and solidifies it loses potential energy and changes to kinetic energy
Answer:
C. The criterion of minimizing chemical waste favors the use of organic solvents.
Explanation:
I chose B on my quiz and got it wrong, then it showed that C was the correct answer. I didn't know this one myself.
The moment the question mention Diamond, suspect Carbon as the answer. (1) element: C, carbon. Atomic number: 12 (double check on periodic table). (2) Not sure what does the question means, but I guess in the first shell, there will be 2 electrons and the 2nd shell will have 8 electrons (may need to explain it based on electron configuration involving s,p,d and f orbitals). (3) MOST undergoes sharing of electron so they form covalent bond with non metals.
The answer is B to prevent condensation from forming on the agar surface
