Answer:
Environmental cleanup includes removal of heavy metals and other toxic contaminants from the environment and the process is called remediation.
MgF is an ionic compound because it's bond is between a metal and a non-metal
Density = 0.186 g/cm^3
Step 1. Calculate the <em>volume</em> of the block
V = lwh = 9.8 cm × 5.6 cm × 4.2 cm = 230 cm^3
Step 2. Calculate the <em>density
</em>
Density = mass/volume = 42.8 g/230 cm^3 = 0.186 g/cm^3
(<em>There is no metal with this low a density</em>.)
Answer:
I think its the first one
Explanation:
The formula equation is Ca + F2 = CaF2.
