Solutions & Mixtures

A:

How fast candy dissolves in water depends on how much candy is used, the temperature of the water, the composition of the candy and its surface area. The duration can range from minutes to hours or even longer. Candy is composed mostly of sugar, which is very soluble in water, so although the dissolving process should not take long, an exact figure is impossible to give without knowing all variables.

  • What are some examples of viscous liquids?

    Q: What are some examples of viscous liquids?

    A: Some examples of highly viscous liquids are oils, honey, glycerin, tar and sulfuric acid. Viscosity is the ability of substances, especially fluids, to resist flow. It can also be referred to as the measure of the ability of a liquid to resist being deformed by extensional stress.

  • How do you identify heterogeneous and homogeneous mixtures?

    Q: How do you identify heterogeneous and homogeneous mixtures?

    A: Heterogeneous and homogeneous mixtures are identified by the level at which the mixtures blend together. Visible indications of different components within a mixture denote a heterogeneous mixture, while a uniform, single-component appearance indicates a homogeneous mixture.

  • What is the meaning of evaporation?

    Q: What is the meaning of evaporation?

    A: Evaporation describes the process of a liquid changing to a gas. Usually, the surface parts of a pool of liquid vaporize into a vapor or gas first. Evaporation occurs in both cold and warm liquids.

  • What happens when you mix salt with water?

    Q: What happens when you mix salt with water?

    A: Mixing salt with water results in the salt dissolving in the water to produce a saline solution. The salt splits up into positively and negatively charged ions that exist independently in the solution.

  • How does hydrogen peroxide kill bacteria?

    Q: How does hydrogen peroxide kill bacteria?

    A: Hydrogen peroxide kills bacteria by oxidizing their cell walls, stealing electrons from them and disrupting their chemical structures. Hydrogen peroxide is a compound with two hydrogen atoms and two oxygen atoms. It is very similar to water, but it has an extra oxygen atom that is shed readily to react with its environment, often in ways that are destructive to surrounding organisms.

  • What is the difference between a mixture and a compound?

    Q: What is the difference between a mixture and a compound?

    A: A mixture is formed when two or more substances are physically mixed together. A compound is formed when two or more substances are chemically combined through a chemical reaction. The components of a mixture can be separated with relative ease, whereas the components of a compound are almost impossible to separate without a chemical reaction.

  • Why does paint peel off walls?

    Q: Why does paint peel off walls?

    A: Peeling paint can be due to any of three common causes, including lack of surface preparation, moist walls and wrong paint, according to Red Beacon. If the wall underneath is dirty, wet or covered in old paint, the paint on top of the bad layer may not hold properly. One way to fix peeling paint is to paint the wall correctly after scraping off the malfunctioning layers.

  • What type of acid is in vinegar?

    Q: What type of acid is in vinegar?

    A: Vinegar contains acetic acid. Acetic acid is derived from alcohol, as bacteria in the air turn it from ethanol to acid, though the acid is diluted in commercial vinegar.

  • Why are oil and water immiscible?

    Q: Why are oil and water immiscible?

    A: Water and oil do not mix because of their molecular properties. On one hand, water has a slight positive charge and is attracted to atoms and molecules with a negative charge. Oil is an electrically neutral substance and has no affinity for water. Water molecules also have high surface tension and are strongly attracted to each other. A surface-active intermediary is necessary for water and oil to mix.

  • What is a filtrate in chemistry?

    Q: What is a filtrate in chemistry?

    A: In chemistry, a filtrate is a liquid that has passed through the filtration process. In this process, liquid is strained. Bigger particles get stuck in the strainer, while smaller particles and liquid pass through, becoming filtrate.

  • Why does iodine turn starch blue?

    Q: Why does iodine turn starch blue?

    A: Starch when mixed with Iodine turns a deep shade of blue because starch contains amylose. Amylose is a soluble component of starch as well as other carbohydrates.

  • What are bricks made of?

    Q: What are bricks made of?

    A: Bricks are made with the two most abundant materials on Earth: clay and shale. These two materials are then put in a furnace, called a kiln, and heated to 2,000��F (approximately 1,100��C). By a chemical process (vitrification), the materials fuse together and form bricks.

  • How does filtration work?

    Q: How does filtration work?

    A: Filtration is a method of separating solid impurities from liquid by allowing the liquid to pass through a filter, which usually consists in a porous material such as cotton wool, cloth, paper, glass wool or asbestos. The filter traps solid particles, and the size of its pores or holes determines which particles pass through. Water flows through the material at a low speed.

  • Is helium gas used to fill a balloon a substance or a mixture?

    Q: Is helium gas used to fill a balloon a substance or a mixture?

    A: Most of the helium gas used to fill balloons is a mixture because commercial helium is seldom pure. Usually, it contains impurities in the form of nitrogen and oxygen gas. However, the helium present in this mixture is also a substance.

  • What is the difference between a solution and a suspension?

    Q: What is the difference between a solution and a suspension?

    A: A solution is a mixture featuring solutes that have been dissolved, while a suspension is a mixture of liquids also containing solid particles that may not completely dissolve inside the liquid. Materials that dissolve in liquids are considered soluble. When no more solute dissolves in a particular solvent while temperature remains the same, the solution is considered to be saturated.

  • Is bleach flammable?

    Q: Is bleach flammable?

    A: Bleach, which is essentially chlorine dissolved in water, is not a flammable substance on its own. If mixed with certain materials such as ammonia or acetylene, it can become unstable, forming explosive compounds or reactions.

  • Why does iodine sublime rather than melt and boil?

    Q: Why does iodine sublime rather than melt and boil?

    A: When iodine is heated, the intermolecular bonds are broken and the iodine goes directly to vapor from solid crystalline form. This is because the bonds are too weak to sustain liquid form under those conditions (slightly above room temperature and standard atmospheric pressure). If you were to continue heating the iodine, it would eventually melt at 113.6 degrees Celsius, and it would boil at 185 degrees C.
