The law of conservation of mass says that matter cannot be created or destroyed. This means that when a chemical reaction happens, you can never create new atoms or destroy the ones that are reacting, they simply rearrange themselves into new substances.
For purposes of looking at chemical equations, this means that the equation that describes the reaction has to be "balanced". In other words, there must be the same number and same kind of atoms on the reactant side of the equation as there are on the product side to ensure that no atoms are created or lost during the reaction.

Explanation:
Bones, lungs, and the liver are the most common places for cancer cells to spread, or "metastasize." Once in the bone, these cancer cells can form new metastatic tumors.
...
Bone metastasis is more likely with cancers such as:
Breast.Prostate.Lung.Kidney.Thyroid.
Sand and water can be separated by any of the following methods:
1. Sedimentation and decantation: This method involves the mixture being kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container. Now, water is poured into another container to separate it from sand.
2. Filtration: This method involves the mixture being passed through a filter paper (a filter with very fine pores). Sand particles being larger in size are retained by the filter paper and get separated from water.
I hope this helps! :D
Explanation:
This situation is analogous to a double replacement reaction. A double-replacement reaction occurs when parts of two ionic composites are exchanged, making two new composites. One characteristic of this kind of reaction is that there are two compounds as reactants and two different compounds as products. So, in this case we can relate with it because there are two new couples with the same members that formed the previous couples.
