The answer is A because Ag and Cu switch places- a SINGLE change occurred :) hope this helped!!
Because pressure (P) is directly proportional to n # of moles. So in a limited space (volume), as more gas is placed inside the closed container, the higher the pressure of the gas that the particles exert on each other and the container.
Salutations!
A change that occurs when a solid melts or a liquid freezes is an example of a _____ change.
A change that occurs when a solid melts or a liquid freezes is an example of a phase. change. A phase change is when one state of matter changes into another state of matter.
Thus, your answer is option B.
Hope I helped :D
Answer:
True
Explanation:
A disaccharide is a sugar and the general molecular formula of a disaccharide is C₁₂H₂₂O₁₁.
A disaccharide is formed when two monosachharide units are joined by a covalent bond called the glycosidic bond.
The glycosidic bond in a disaccharide is formed by dehydration reaction between the two monosachharide units. The removal of the water molecule results in the formation of the glycosidic linkage.
For example: maltose a disaccharide, is formed when two molecules of glucose are joined by a (1→4) glycosidic bond. As, the glycosidic bond is formed between the carbon 1 of one glucose unit and carbon 4 of another glucose unit.
Therefore, in a disaccharide the two monosaccharide units are joined by a glycosidic bond or linkage.
Therefore, the given statement is TRUE.
