Answer:
1.8g
Explanation:
Initial volume = 43.5ml
Final volume = 49.4ml
Mass = 10.88g
Density = ?
Volume = Final volume - initial volume
= 49.4 - 43.5
= 5.9ml
Density = Mass/volume
Density = 10.88/5.9
= 1.8g/ml
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>
<span>When electrons shared unequal atoms such as hydrogen
and oxygen atom, one atom will get more of the common electrons and it will be slightly
negatively charged. The other atoms who gets less electron will be slightly
positively charged. This chemical condition describes water as a polar
molecule. The oxygen atom pulls the shared electrons more strongly than do the
hydrogen atoms within each of the two polar covalent bonds.</span>
