Answer:
no it dosen't matter
Explanation:
because it absorbed the light so it had to damage it.
The answer to your question is 12.01. I really hope this helps!
Answer:
The Relative Formula Mass of Fe(NO₃)₂ is 179.8524 grams
Explanation:
The Relative Formula Mass is the mass of one mole of a compound expressed in grams, obtained by adding together the Relative Atomic Masses, RAM, of the elements which makes the compound
The Relative Formula Mass of a compound is the same as its Relative Molecular Mass
The relative formula mass of Fe(NO₃)₂ is given as follows;
The relative atomic mass of Fe = 55.845 amu
The relative atomic mass of nitrogen, N = 14.0067 amu
The relative atomic mass of oxygen, O = 15.999 amu
Therefore, we have;
The formula mass of Fe(NO₃)₂ = (55.845 + 2×(14.0067 + 3×15.999)) amu = 179.8524 amu
The Relative Formula Mass of Fe(NO₃)₂ = 179.8524 grams.
Depending on the magnitude of radiation, the effects of exposure vary too. In this case, it is assumed that the small amount of radiation here has a very high radioactivity, then definitely it can cause DNA changes. In any way, it is rare that radiation affects the lining of the lungs and can cause illnesses such as emphysema and asthma. answer is A.
Answer:
yes, the number of protons makes an atom whatever element it is, and the number of protons cannot be changed, because changing the number of protons would change what element it is. the number of protons in each element is unique.
