Density can be calculated using the following rule:
density=mass/volume
therefore,
volume=mass/density
we have mass=0.451g and density=0.824g/ml
substituting in the above equation, we can calculate the volume as follows:
volume = 0.451/0.824 = 0.547 ml
Answer:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Explanation:
MgCl2 (s) + Li2CO3 (s) ==> MgCO3 (s) + 2LiCl (aq)
Double Replacement
Halogens are Soluble
Carbonates are Insoluble
This reaction DOES take place.
The answer is C. Isotopes.
Isotopes are defined as two substances that have the same number of protons and electrons, but a different number of neutrons, and therefore a different atomic mass. For example, carbon-12 and carbon-14 are isotopes of each other.
Hope this helps!
