Identifying Types of Chemical Reactions Identify the reaction type for each generic chemical equation.
A+B - AB:
AB - A + B :
Hydrocarbon + O2 - CO2 + H20:
AB + CD AD + CB:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
