The following statements apply:
1. Salt is not chemically bonded to water.
2. The ratio of salt to water may vary.
3. Salt and water retain their own chemical properties.
The solution formed by dissolving salt in water is an example of a mixture, it is a physical change and no new substance is formed. The salt and the water are not chemically bonded and salt can easily be recovered from the water by mean of evaporation. Any amount of salt can be dissolved in the water and each of the component, that is, salt and water still retain their individual chemical properties.
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.
