20 maj 2018 · The activity series is a list of elements in decreasing order of their reactivity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series. The table \(\PageIndex{1}\) below is an activity series of most common metals, and the table \(\PageIndex{2}\) is an activity series of the ...

- The Activity Series
Use the activity series to predict if the following reactions will occur. If not, write \(\text{NR}\). If the reaction does occur, write the products of the reaction and balance the equation.
28 lut 2020 · The activity series of metals is an empirical tool used to predict products in displacement reactions and reactivity of metals with water and acids in replacement reactions and ore extraction. It can be used to predict the products in similar reactions involving a different metal.
Identify and name a variety of everyday materials including wood, plastic, glass metal, water and rock. Compare and group everyday materials on the basis of their properties, including their hardness, solubility, transparency, conductivity (electrical and thermal) and response to magnets.
The activity of component A (a A) can be calculated from the concentration of component A in solution ([A]) and its activity coefficient (γ. A) by. aA = [A] γA. Thus, and. The reason KN changes with the salt concentration is that the activity coefficients depend on the concentration of the salt.
Compare and group together a variety of everyday materials on the basis of their simple physical properties. Identify and compare the suitability of a variety of everyday materials for particular uses. Concepts supported. Children will learn: That different materials have different properties.
This Chemical Sciences unit investigates the observable properties of materials. Descriptive vocabulary is explored as well as the suitability of materials for different purposes. It consists of 6 lessons of approximately 60 minutes duration.
