A4.3.10.1 Reactivity

The presence of an amine group strongly increases the reactivity of the aromatic ring, due to an electron donating effect.

Ease of decomposition When metals are near the bottom of the reactivity series, their compounds generally decompose easily at high temperatures.

Geological resistance is a measure of how well minerals resist erosive factors, and is primarily based on hardness, chemical reactivity and cohesion.

This means that when the negative mood returns, for any reason, it will tend to trigger all the other symptoms a process called cognitive reactivity ).

Over time, if uncorrected, major depression can cause such conditions as progressive mineral loss from bones, accumulation of abdominal fat, increased blood platelet reactivity, and increased risk of cardiovascular disease.

Fortunately the designers had made provisions in the design to increase the reactor's reactivity (the number of neutrons per fission that go on to fission other atoms of nuclear fuel).

The reactivity of a chemical substance is a description of how it might react across a variety of potential chemical systems and, for a given system, how fast such a reaction could proceed.

Moreover, individual habits such as diet, exercise, the quality and quantity of sleep, and substance abuse also play a major role, as do early life experiences that set life long patterns of behavior and physiological reactivity.

Stereochemistry includes methods for determining and describing these relationships the effect on the physical or biological properties these relationships impart upon the molecules in question, and the manner in which these relationships influence the reactivity of the molecules in question (dynamic stereochemistry).

A4.3.10.1.1 Describe the reactivity hazards of the substance or mixture in this section. Provide specific test data for the substance or mixture as a whole, where available. However, the information may also be based on general data for the class or family of chemical if such data adequately represent the anticipated hazard of the substance or mixture.
