The answer that best completes the statement above is EXTENSIVE LAVA FLOW. Maria is the name that refers to an asteroid family. And this has punctured the surface of the moon which created magma to bleed out and resulted in an extensive lava flow. Hope this answer helps.
Explanation:
A mixture which shows presence of uniform composition of solute particles into the solvent is known as a homogeneous mixture.
- Distilled water is a clear solution in which there is uniform composition of solute particles into the solution.
- Gasoline is mixture of different compounds which are evenly distributed. Therefore, it is also a homogeneous mixture.
- Wine is also a clear solution in which particles are evenly distributed. Hence, it is a homogeneous mixture.
On the other hand, a mixture which shows non-uniform composition of solute particles into the solvent is known as a heterogeneous mixture.
- Beach sand is a mixture of different particles present in varying composition. Hence, it is a heterogeneous mixture.
- Also, in air there are different gases present in different composition. Mover over, there is presence of fog and smoke into the air. Hence, it is a heterogeneous mixture.
We are given that the concentration of the KCl is 2 meq /
mL. Assuming that the ampule also has exactly this concentration, therefore:
amount of KCl in ampule = (2 meq / mL) * (20 mL)
amount of KCl in ampule = 40 meq
This amount of KCl is now inside a solution of 1 Liter (also
equivalent to 1000 mL), therefore the new concentration in the resulting
solution is:
new concentration = 40 meq / 1000 mL
new concentration = 0.04 meq / mL
Since 0.04 in decimal is 4% in percentage, therefore the
strength of the resulting solution is 4% KCl.
The fronts shown on the weather map are best described as Cold and Warm fronts.
