Answer:
Bio gas
Explanation:
Bio gas is gotten from the anaerobic breaking down of biomass especially animal waste.
PROS:
A. it is renewable: biogas is renewable and has an endless supply of material since animals are the main source when compared to fossil fuels.
B. It doesn't involve a rigorous mining exersice to get to like fossil fuels and it is in accessible abundance.
CON:
A. A lot of waste is needed for the product of biogas and the final waste (sludge) from the production process can be a huge problem to dispose off.
B. Some of the gases liberated in the manufacturing process are greenhouse gas, especially methane. These gases if let out, will contribute immensly to global warming.
c. All materials that need to be sterilized can be autoclaved.
As a widespread rule of thumb, you can not autoclave materials that can be infected with solvents, radioactive materials, risky or corrosive chemicals, or items that contain mutagens, carcinogens, or teratogens.
The catheter is a soft instrument, manufactured from polymers instead of any steel substance. The high warmness and water pressure of the autoclave can cause the polymer to melt or get broken.
Chlorides, sulfates, chlorine, hypochlorites, bleach, and acids aggressively attack chrome steel and might reason great damage to the autoclave chamber and plumbing. Hypochlorites, acids and bleaches are so caustic that they ought to never be sterilized or used to easy an autoclave.

B. Decreasing the surface area of solid reactant;
Why? Collision theory suggests that the more opportunities for reactants to come into contact or "collide" with other reactants, the faster the reaction will take place. Hence, decreasing the surface area will decrease the probability of collisions between reactants thereby decreasing reaction rate.
