Chemical properties describe how things undergo chemical reactions, while physical properties describe how things behave when they're not undergoing reactions.
In the case of melting a metal, the melted metal continues to be the same material - just in a liquid rather than a solid form. As a result, melting (and all phase changes, for that matter) is a physical change and the ability of the metal to melt at 450 degrees is a physical property.
Answer:
H2 + O2
Explanation:
H2 + O2 --> H2O
The items on the left side is the reactants. The arrow means yields, and the item the arrow is pointing at is the product.
Answer:
0.321M would be the concentration of the final solution
Explanation:
In the problem, you are decreasing the concentration of a solution (The stock solution) by the addition of more solvent (This process is known as dilution).
You are increasing the volume of the solution from 15mL to 700mL, that means the solution <em>is diluted:</em>
700mL / 15mL = 46.67 times
Now, to know the concentration of a final solution we need to take the concentration of the stock solution. <em>Assuming the stock solution is 15M:</em>
15M / 46.67 =
<h3>0.321M would be the concentration of the final solution</h3>
