Answer:
Protons
Explanation:
I'm not exactly sure if this is what your question, but the number of protons is what makes an atom that atom. If you change the number of proton it is now a different atom. You change the number of electrons and get an ion or change the number of neutrons and get an isotope but you can't change the number of protons as you would be changing the elemnt.
D = m / V V = m / D V = 4770 g / 7.86g/cm³ V = 606.9 cm³
V = 606.9 cm³ x (1 dL / 100 cm³) V = 6.069 dL
The answer, 6.07 dL, is reported to three significant digits due to the precision reported for the density.
Answer:
A. Sugar
Explanation:
Sugar dissolves in water because of its molecular structure (C6H12O6), as the sugar is put in the water, energy is released and the polarity of the water breaks apart the molecules. However, the molecules can be obtained back by evaporating the water.
