Q:

What is a sucrose gradient?

A:

Quick Answer

A sucrose gradient is a type of density gradient used to obtain the centrifugal separation of differently sized particles. Sucrose gradients are made by layering sucrose solutions of decreasing concentrations into a centrifuge tube to create a gradient of decreasing density or viscosity.

Full Answer

Centrifugation is a technique used to separate small particles of different size, shape or density by subjecting mixtures of particles to high rotational speeds. Particles with different attributes sediment or migrate at different rates during centrifugation, allowing them to be isolated. Several types of centrifugal separation techniques rely on the use of density gradients such as sucrose gradients to stabilize or differentiate separate groups of sedimenting particles.

    What is the enthalpy of hydration?

    A:

    The enthalpy of hydration is the change in enthalpy when an ion is dissolved in water to infinite diluteness. Enthalpy is a thermodynamic term for the internal energy of a system plus the product of the pressure and the volume of the system. Enthalpy of hydration is always negative.

    What are sources of carbon monoxide?

    A:

    Carbon monoxide is a poisonous gas that is produced from the incomplete burning of fossil fuels, such as coal, oil, wood, charcoal, kerosene, propane and natural gas. It is also produced by products that use internal combustion engines, including cars, lawn mowers, motorcycles and generators. Certain modern industrial processes, such as iron smelting, produce carbon monoxide, as do some natural phenomenon, such as volcano eruptions and forest fires.

    What is rubber made out of?

    A:

    Natural rubber is made from the sap of a tree, and synthetic rubber is created from chemicals found in petroleum. Rubber trees first originated in South America, and the sap is called latex. The latex oozes from the bark of the rubber tree and can be easily collected to form balls or other objects.

    What is a homogeneous compound?

    A:

    A homogeneous compound is a compound in which individual components are uniformly mixed throughout the compound. Homogeneous compounds are consistent in their composition and are only present in one state of matter at a time. An example of a homogeneous compound would be a metal alloy, such as steel.
