Answer:
Carbon based molecules have 3 main structures which are
straight chain
branched chains
rings
Explanation:
The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.
Answer:
d. The effectiveness of an autoclave is dependent on an increase in pressure and corresponding increase in temperature.
Explanation:
Autoclaving is a heat treatment widely used in the hospital environment and consists of keeping contaminated material at a high temperature through contact with water vapor for a period of time sufficient to destroy all pathogens.
The process includes compression and decompression cycles to facilitate contact between vapor and contaminated materials. The usual pressure values range from 3 to 3.5 bar and the temperature reaches 135ºC. Having the advantage of being relatively simple and can be used to sterilize various types of hospital supplies. Thus, we can conclude that the effectiveness of an autoclave depends on a pressure increase and corresponding temperature increase.
Answer:
Kinetic Energy can be defined as the energy possessed by the object by the virtue of its motion. The sum of these two energies is often called Mechanical Energy of the System. Electric Energy is also a form of these 2 energies: Electric potential energy stored in a charged particle in an electric field.
