I’m pretty sure it’s single replacement
For example
Na2CO3
[na=23 o=16c=12]
2x23+12
+16x3
46+12+48
106
%comp of Na=46/110x106=44%
%comp of C =12/110x106=12%
% comp o O=48/110x106= 46%
Answer:
B. Mixing a solute and a solvent
Explanation:
Hello,
In this case, solutions are defined as liquid homogeneous mixtures formed when two substances having affinity are mixed. It is important to notice that the two substances are known as solute, which is added to other substance that is the solvent. Therefore, answer is B. Mixing a solute and a solvent.
Notice that when two insoluble substances are mixed no solution is formed. Furthermore, if two solutes together or a solute and a precipitate are mixed, no liquid homogeneous solution is formed, as commonly solutes are solid, nevertheless, when liquid, one should have to act as the solvent.
Best regards.
