What is "protic solvent"?

Solvents are materials, usually liquids, used to dissolve one substance into another. There are protic and aprotic solvents. Protic solvents are capable of donating protons. The -OH group on protic solvents is their most distinguishable feature, although some protic solvents do not contain an -OH group. Nitromethane, with a chemical formula of CH3NO2, is one such example. Aprotic solvents do not contain an -OH group. Instead, they contain a C=O bond. Examples of aprotic solvents include acetone and ethyl acetate.

What does a sundial do?

The numbered dial has multiple lines to indicate the hour of day. The style or gnomon is a pointer that resembles a straight edge or a thin rod. When the sun moves during the day, the shadow-edge of the style aligns with a corresponding hour line.

What is vascular tunic of the eye?

The choroid is the posterior, or back, portion of the eyeball that provides blood supply toward the back of the eye. The choroid also gives rise to the ciliary body and iris. The ciliary body is located between the choroid and the iris. It features a circular layer of muscles that help control the iris for the ability to focus. The iris is known as the colored part of the eye. It is also made up of muscles that control the size of the pupil, which adapts with the amount of light for better focusing, explains class notes from Austin Peay State University.

What were the names of the three astronauts on the Apollo 13 mission?

The seventh manned mission in the Apollo space program, Apollo 13 was intended to land on the moon two days after its launch, according to Wikipedia. This, however, didn't happen, due to an explosion of an oxygen tank which crippled the service module. This forced the crew to shut off most of the electrical equipment on board to conserve battery power. Despite this, and the related challenges, Apollo 13 returned to Earth safely on April 17, 1970.

What are examples of distillation?

One method of distilling water at home involves heating water in a pot with a smaller container inside the pot. An inverted lid on the larger pot provides a collection point for the vapor that forms when the water is heated. Putting ice on the lid cools the steam and converts it back into a liquid. As the water liquefies, it moves to the center of the lid and drips into the smaller container.\nFractional distillation of petroleum uses the variations in boiling points of the components of crude oil to separate them. The refiner heats crude oil, and the vapors pass through a condensing tower. Th..

What are coniferous forest soil types?

In addition to being thin and relatively acidic, podzol soils are quite infertile. The infertile nature of these soils makes them ideal for supporting the growth of strong and sturdy evergreen trees, which are, like their supporting soils, quite versatile to environmental conditions and can thrive in extreme temperatures and subpar growing conditions. Podzol soils have very few minerals and nutrients, as the few nutrients that collect on and just below their surfaces tend to wash away in the spring following snowmelts. Most forests contain soils rich in decomposing plant and animal matter, whi..
