Explanation:
Answer:
The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate.
Surface area is 54cm^2, volume is 27cm^3
and surface area-to-volume ratio is 2
Answer:
This question is asking to state what is being defined. The term defined in the question is called DIFFUSION
Explanation:
Diffusion is the movement of particles/fluids from a region where they are highly concentrated to the region where they are less in concentration across a space. Diffusion is a form of passive transport i.e does not require energy input to occur. This is because the movement occurs down a concentration gradient.
A concentration gradient i.e difference in concentration occurs when there is an uneven amount/concentration of particles in two regions. Hence, movement occurs naturally to the direction where the particles are less concentrated from where they are more concentrated.
Fuel combustion from motor vehicles (e.g. cars and heavy duty vehicles)
Heat and power generation (e.g. oil and coal power plants and boilers)
Industrial facilities (e.g. manufacturing factories, mines, and oil refineries)
Municipal and agricultural waste sites and waste incineration/burning.
