Answer:
b. some sodium iodide will precipitate out of solution
Explanation:
We know that for salts solubility decreases as the temperature of the solution decreases. So, NaI being a salt, its solubility will surely decrease when the temperature is cooled down to 25°C from 50°C.
Thus,the undissolved sodium iodide will precipitate out of the solution.
The given statement is true, because the activation energy must be provided in order for the molecule to reach the transition state because it is a high-energy state. Reactant molecules don't stay in the transition state for very long since it is unstable; instead, they move on to the next phase of the chemical reaction right away.
To create a successful transition state (with lower activation energy). Heat, which is the most frequently employed energy source, favours the breakdown of processes and lowers the amount of energy needed when the enzyme attaches to the substrate.
The remainder of the process can be completed once the molecule has taken in enough energy to reach the transition state.

A liquid with high viscosity does not flow easily and is not effective in wetting a surface.
When a metal is subjected to corrosive elements including salt, moisture, and high temperatures, a reaction called corrosion takes place inside the metal. Some foods contain metallic compounds that can corrode a material. The majority of corrosion is simply surface dis-colouration, which polishing agents may quickly remove.
Increasing viscosity and constant intermolecular water bonding together result in surface tension. Any liquid that was more viscous than water possessed a surface tension that was equal to or lower than that of water. Viscosity with surface tension decrease when temperature rises.
Therefore, a liquid with high viscosity does not flow easily and is not effective in wetting a surface.

Plasma is the fourth state of matter. Plasma occurs at extreme high temperatures. It is found in stars, lightning, and neon lights. Plasma is the most commonly found matter in the universe, even though its not common on earth.
In crystalline solids, the particles are arranged in a repeating, three dimensional pattern called a crystal. Some forms of crystalline solids are table salt, sugar, sand, and snow. Diamonds are also crystalline solids.
Gas is a matter that does not have a definite shape or volume.The particles in gas are much father apart than those in a liquid or solid. Gas particles move at high speeds in all direction.
Plasma is different because it can only exist in extremely high temperatures. It is not common on Earth, like the other states of matter. It is only common in the universe. Plasma is found in a lot of things in space. Plasma is not bound to one atom, so it is free. Plasma is formed by adding more heat to the molecules of gas. Eventually, the molecules are moving so fast, that they break apart from their atoms, and then they are positively charged ions, or plasma.
