Answer:
THE TEMPERATURE AT WHICH THE CHEMICAL REACTION IS BEING CONDUCTED.
Explanation:
The reaction rate constant is dependence on the temperature in which the reaction takes place. The rate of a reaction and the activation energy relationship is given by the Arrhenius equation with the rate constant as a function of temperature.
Mathematically, the rate constant is expressed as;
k(T) = Ae^-Ea/RT
where Ea is the activation energy, R is the gas constant, Ae is the pre-exponential factor and it is the frequency at which a reactant molecule collide with each other, T is the temperature.
Ecological succession is the steady and gradual change in a species of a given area with respect to the changing environment. it is a predictable change and is an inevitable process of nature al all the biotic components have to keep up with the changes in our environment.
Answer:
Fe + CuCl2 = FeCl2 + Cu
Explanation:
This is already balanced.
The right answer is screening test.
In medicine, screening consists of looking for one or more diseases or abnormalities known as "at risk" in individuals of a given population.
These investigations are followed or not by medical consultations, clinical examinations and treatments.
In addition, screening is a preliminary procedure (test or examination) to detect one or more characteristic signs or symptoms of a disease or syndrome and potentially leading to further investigation.
