Find the molar mass of CaCO3 then subtract the molar mass what it originally weighed and the loss of mass. Hopefully this works!
The answer should be D, cells can only create an identical copy of the original cell.
Answer: It means that the energy is being stored or preserved to be used at a later time.
Your question was a little vague, so if this isn't the answer you were looking for, just let me know and I'll fix it.
Hope this helps! Good luck! :D
0.83 m/s seems the correct answer, hope it helps
Answer:
n=6 to n=3 (B)
Explanation:
Energy of an electron present in the orbit is directly proportional to .Hence a transistion from one orbit to another orbit emits an energy proportional to the difference of their squares of the orbits. that is if an electron travels from orbit n1 to orbit n2 then it emits an energy corresponding to .So in the above question the highest energy emission occurs when an electron moves from n=6 to n=3.(Highest difference of energy levels).
