<span>The organizational characteristics of the periodic table of the elements are within a system where all known elements are classified. They are placed from left to right and top to bottom in increasing order of their atomic numbers. The elements are arranged in seven horizontal rows called periods, and in 18 vertical columns called groups or families. Down and to the left increases the atomic radius and the ionic radius. Upwards and to the right increases ionization energy, electron affinity and electronegativity.</span>
C. when electrons are transfered, and a pathway for electrons is provided.
Answer:
What is a formation reaction? it is when a mol of a product it is formed from its elements constituents
What is standard heat of formation? the standard heat of formation or formation enthalpy, it is the amount of energy necessary for produce a mol of the product when its elements constituent react.
What is a combustion reaction? It is when a hydrocarbon reacts with oxygen and produce water a carbon dioxide
What is standard heat of combustion? It is the amount of energy released during a combustion reaction, measuring per mass or volume unit
Explanation:
A example of formation reaction is:
2H2 + O2 =2H2O
I hope my answer can help you
Both processes use and make ATP
