Answer:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Explanation:
Answer:
Gold has a high conductivity
Explanation:
This is because gold is a metal that occur free in nature in rocks, alluvial , grains e.t.c. it is a transition metal and in group 11 of the periodic table do it conduct electricity. It has has conductivity because it is a metals because all metals have ability to conduct electricity. When it is pure, it is a bright, slightly reddish yellow, . It is soft, malleable.
It is a ductile metal
and ductile metal.
You would have to look for the mass of the sample and the volume of the sample.
Tough question, I would suggest using Google maybe, or just plain out asking your science teacher.
