Which goal or task most likely be achieved in applied chemistry not pure chemistry?
The goal is the finding of practical applications for chemical reactions and chemical products.
Why are 18 group elements called noble gases?
According to the classical shell model for electrons, the group 18 elements have a fully filled outer shell, rendering them inert to most chemical reactions (little tendency to participate in chemical reactions ). So they are called noble or inert gases
Does chemical reactions need water?
Yes, most chemical reactions involved in metabolism do require water.
What are the only electrons that participate?
In most cases it is the valance electrons which participate in chemical reactions. Transition state elements are a major exception; they undergo reactions that involve the inner electron shells as well.
What chemical reactions are most common to break down the molecules?
These are decomposition reactions.
Is ATP the primary source of energy for chemical reactions?
Most likely.
Do elements in a group have different charges?
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.
What family of elements contains elements most likely to gain an electron in chemical reaction?
Nonmetals, expecially halogens.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
Which goal or task most likely be achieved in applied chemistry not pure chemistry?
The goal is the finding of practical applications for chemical reactions and chemical products.
Which elements are most likely to react in the same manner in a chemical reaction?
A pair of elements in the same group are more likely to have similar properties. This is why groups are also called families. In the main group elements, groups 1,2, 13-18, the elements in a group have the same numbers of valence electrons in their outermost energy levels. This accounts for the fact that they behave in a similar matter in chemical reactions.

Which goal or task would most likely be achieved in applied chemistry not pure chemistry?
The goal is the finding of practical applications for chemical reactions and chemical products.
Which pair of elements are most likely to form an ionic compound P and Br or Zn and K?
K and Br are most likely to form a chemical compound.
What element speeds up chemical reactions?
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
What are the only electrons that participate?
In most cases it is the valance electrons which participate in chemical reactions. Transition state elements are a major exception; they undergo reactions that involve the inner electron shells as well.
