Answer:chemistry is a subject that deals with composition of substances and of the changes which they undergo in consequences of alteration in the constitution of molecules which depend upon variation of the number, kind or mode of arrangement of the constituent atom while biology deals with characteristic life processes and phenomena of living organisms
Explanation
Answer:
placing the reactants on a hot plate
Explanation:
If the temperature goes up, the reaction rate will increase. Because the particle will move faster and makes the kinetic energy larger.
The noble gas configuration system helps to shorten the total electron configuration by using the symbol for the noble gas that lies before the particular element in the periodic table.
For example:
Na has atomic number 11
Electron configuration of Na: 1s2 2s2 2p6 3s1
Noble gas electron configuration of Na: [Ne] 3s1
Ne has atomic number 10 and lies before Na in the periodic table.
Answer:
the other number is different
