A solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solution must beA)dilute B) saturated C) unsaturated D) supersaturated
Answers
Answer: Option (B) is the correct answer.
Explanation:
A solution that has maximum concentration of solute particles and on adding more solute the particles of solute remains undissolved is known as a saturated solution.
Whereas when particles of solute keep on dissolving in a solution then it is known as an unsaturated solution.
Thus, we can conclude that a solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solution must be saturated.

Ethyleneoxideisthechemicalagentsusedforsterilization.
Final answer:
Ethylene oxide is the chemical agent used for sterilization amongst those listed in the question. This gas sterilizes by disrupting the DNA of microorganisms. Other agents listed, such as chlorine, alcohol and phenolics are generally considered disinfectants, not sterilants.
Explanation:
Out of the chemical agents listed, ethylene oxide is the one commonly used for sterilization. Ethylene oxide is a gas that sterilizes by penetrating and disrupting the DNA of microorganisms, preventing them from reproducing. It is frequently used to sterilize medical and laboratory equipment, particularly items that cannot be sterilized by high heat such as plastic, electrical equipment, and delicate instruments.
While chlorine, alcohol, and phenolics can kill many microorganisms, they are generally considered disinfectants rather than sterilants because they may not kill all types of bacteria, viruses, fungi, and spores. Soap is typically used for cleaning, not specifically for its antimicrobial properties.

B. A 2 kg pot at 120°C
C. A 5kg pot at 25°C
D. A 2 kg pot at 25°C
Answers
Final answer:
The 2 kg pot at 25°C has the least thermal energy because it has both a smaller mass and a lower temperature than the other options.
Explanation:
The thermal energy of an object is related to both its mass and its temperature. In this case, we are considering iron pots of different masses and temperatures. Given the options, the 2 kg pot at 25°C would have the least thermal energy. This is because it has both a smaller mass and a lower temperature than all the other options listed.
The thermal energy is calculated by multiplying the mass, specific heat, and change in temperature. An object with a smaller mass and lower temperature would therefore have less thermal energy.

Answer : The total mass of oxygen gas released in the reaction will be, 12.8 grams
Explanation :
Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The balanced chemical reaction will be,
According to the law of conservation of mass,
Total mass of reactant side = Total mass of product side
Total mass of = Total mass of
or,
Total mass of = Mass of
+ Mass of
As we are given :
Total mass of = 16.12 grams
The mass of = 9.72 grams
So,
Total mass of = Mass of
+ Mass of
Therefore, the total mass of oxygen gas released in the reaction will be, 12.8 grams
Final answer:
The law of conservation of mass states that the total mass remains constant before and after a chemical reaction. In the decomposition of magnesium oxide into magnesium and oxygen, the mass of oxygen gas released can be found by subtracting the mass of the substance after the reaction (magnesium) from the mass before the reaction (magnesium oxide), resulting in 6.40 g of oxygen gas.
Explanation:
The question pertains to the law of conservation of mass, which states that mass is neither created nor destroyed. It is also linked to the third postulate in Dalton's series. In the case of magnesium oxide decomposing into magnesium and oxygen, you can use this law to solve the problem.
If 16.12 g of magnesium oxide decomposes to 9.72 g of magnesium, this means that the rest of the mass must be the oxygen gas released. The mass of the magnesium oxide (16.12 g) minus the mass of the magnesium (9.72 g) gives the mass of the oxygen gas. Therefore, the mass of oxygen gas released is 16.12 g - 9.72 g = 6.40 g.
