Physical change is when something change its physics such as turning water into ice and chemical change is making something then intosomething completely different or new
Because its made of different materials so it could be strong
Answer:
V = 15.6 L
Explanation:
Hello there!
In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:

Thus, given the moles and concentration of the solution, we can find the volume as shown below:
V=n/M
Therefore, we plug in the given data to obtain:
V = 2.5mol /(0.16mol/L)
V = 15.6 L
Best regards!
D is asking basically asking if would you get the same results if the tubes had salt instead of sugar
