color change
A substance with a pH level of 8 is slightly basic. Some examples include seawater, baking soda solution, and eggs.
Table salt is a pure substance because it is composed of only one type of molecule, sodium chloride. Seawater is a mixture of different substances, including salt, water, and various dissolved ions. Sand is a heterogeneous mixture of minerals and particles, making it not a pure substance.
A substance with a pH level of 8 is considered slightly basic. Examples include seawater and baking soda when dissolved in water.
Temperature and Salinity. Both are important although temperature has a much greater effect than salinity on seawater density.
seawater is a homogeneous mixture. The water being the solvent and the salt being the solute. A heterogeneous mixture is mixed but not as thoroughly as a homogeneous mixture. None of these though are chemically combined, none are compounds. (hence mixture)
It is a mixture
No, the process of evaporating water from seawater is a physical change, not a physical property. Physical properties are characteristics of a substance that can be observed without changing the substance itself, whereas physical changes involve a change in the state or appearance of a substance without altering its chemical composition.
Seawater and fresh water contains oxygen that fish absorb using their gill. So the substance is oxygen.
After water, SALT
A substance with a pH level of 8 is slightly basic. Some examples include seawater, baking soda solution, and eggs.
chemistry
Seawater does not have a density of 5.
A solution.
Seawater is a mixture. It is a combination of salt and water that is a homogeneous mixture. An example of a pure substance is either pure salt or pure sugar.
The calcium carbonate is formed.
