Salts get dissolved in water because it has partial positive and negative charges. So option (c) is correct.
<h3>Why does salt dissolves in water?</h3>
The water molecules pull the Na and Cl ions apart while breaking the ionic bond which held them together. After the salt ions are pulled apart, they get surrounded by water molecules. The salt dissolves to form a homogeneous solution.
- The slightly positive portion of sodium is attracted to the slightly negative portion of oxygen on the water molecule. At the same time, the slightly electronegative chlorine moieties of NaCl are attracted to the slightly electropositive hydrogen moieties of water.
- In either case, no true bond is formed, the stronger covalent bonds of water (also commonly held by hydrogen bonds between water molecules) win, NaCl gets pulled apart, resulting in dissociation of Na+ and Cl- ions with the Na+ and Cl- ions setting loosely in place between the intact H₂O molecules. NaCl is then dissolved.
Salts are ionic and are expected to dissolve in water because water itself is polar. Therefore, ionic salts are expected to dissolve in polar solvents.

The independent variable would be the amount of sunlight because that is what you are testing and the dependent variable would be the length of time the mice slept because it is what you are measuring. The constants would be everything else water, food, cage size, exercise wheel, and temperature because they stay the same.
Answer:
mass = 963.53 grams
Explanation:
mass = moles x molar mass
m = 9.45 x 101.96 (molar mass of Al2O3)
m = 963.53g
Steel is an alloy, or a solution of several metallic elements. Although some steels can technically be heterogenous, steel is generally a homogenous mixture/solution.
The energy needs of a cell is very important because they need energy to breakdown,synthesis, and transport nutrients and molecules so an living organism can survive just like how the city needs energy to power its cities so it’s people can do what they need to do to survive. HOPE IT HELPS
