Explanation:

There are three states of matter: Solid, liquid and gas. With change in pressure and temperature, matter changes its state. A solid has closely packed particles while a liquid and gas have loosely packed constituent particles. An outside force either compresses or expands the packed matter which causes it to change the state. On compression, particles come closer and gas changes to liquid and liquid to gas where as on expansion, the solid turns to liquid and liquid to gas.

A technician needs 500.0mL of a 0.500 M MgCl2 solution for some lab procedures. The stock bottle is labeled 4.00 M MgCl2. What v
mihalych1998 [28]

Answer:

Explanation:

To solve this problem, we need to obtain the number of moles of the solute we desired to prepare;

    Number of moles  = molarity x volume

Parameters given;

        volume of solution = 500mL  = 0.5L

          molarity of solution = 0.5M

   Number of moles  =  0.5 x 0.5  = 0.25moles

Now to know the volume stock to take;

           Volume of stock = \frac{number of moles }{molarity}

  molarity of stock  = 4M

                 volume  = \frac{0.25}{4}   = 0.0625L or 62.5mL

Ber [7]

ANSWER: C) Law of Conservation of Mass

EXPLANATION: In the given cycle, it is seen that th sediments are layered and gets compressed into sedimentary rocks which eventually gets heated and compressed to form metamorphic rocks. But, the total amount of minerals present in the sediments remains the same throughout any stage of the cycle.

This proves the law of conservation of mass which states that mass can not be created nor be destroyed, it can only be transferred from one form to another. So, in this case, only phase transition occurred but the component which is mineral inside the sediments remains constant.

Therefore, the answer is law of conservation of mass.
