They include elements 57-71 (lanthanides) and 89-103 (actinides)
It is impossible to run 15 miles an hour

Hope this helps :D
Mass per volume percent is simply calculated by getting the ratio of the mass in g of solute and the volume in mL of the solution multiplied by 100 percent. In the problem, we are given all the required values. Calculation is as follows:
%w/v = 140 / 1590 x 100 = 8.81%
Answer:
Plastic polymers
Explanation:
Plastic polymers are usually made up of synthetic and semi-synthetic polymers such as polyethylene, polystyrene etc.
Plastic polymers have a unique property called malleability. Malleability is the ability of a substance to be moulded into different sizes and shapes.
When hear is applied plastics gets soft and can be molded into different forms and then it becomes hardened after exposure to air(dried).
The plastic polymers are usually very cheap to produce in large quantities which is why it is very common in industries.
