The freezing point is -14.88 degrees celsius
I'm pretty sure it's B because carbon atoms are in all living organisms. They can also be bonded in different varations.
Answer:
Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.
Hope this helps!!!
Molar mass:
iron = 55.8 g/mol
Sulfur = 32.0 g/mol
Number of moles
<span>53.70 / 55.8 = 0.96 moles </span>
46.30 / 32.0 = 1.44 moles
Using the values determines the entire lower proportion in moles of the elements, just divide by the smaller one
Fe = 0.96 / 0.96
Fe = 1 mole
S = 1.4 / 0.96
<span>S = 1.5 moles </span>
multiply them by 2.
iron : 2 * 1 = 2
Sulfur : 1.5 * 2 = 3
<span>the empirical formula is Fe₂S₃</span>
