Answer:
- 484 KJ/mol
Explanation:
The reaction equation is;
CH4(g) + F2 (g) ------> CH3F(g) + HF(g)
The enthalpy of the reaction can be calculated from bond energies using the formula;
ΔHreaction = Bond energy of reactants - bond energy of products
or
ΔHreaction = Bonds broken - bonds formed
[4(413) + 1(155) - 3(413) + 1(485) + 1(567)]
[(1652 + 155) - (1239 + 485 + 567)]
[1807 - 2291]
= - 484 KJ/mol
never consume moldy bread.Store bread properly to avoid these potentially harmful bacteria.
Penicillium
:Penicillin is well known for being one of the most widely prescribed antibiotics in the world, but the fungus used to produce it, penicillium, is also a common bacterium that grows on bread. According to cmsynergy.com, this bacterium prefers colder environments, such as that found in your refrigerator, and will grow on fruit or bread. It will not grow, however, if the relative humidity in the air is less than 60 percent. Penicillium bacteria form colonies that appear as fuzzy blue-green or gray patches on the bread surface. Neurospora Crassa
:This bacterium species thrives on bread and produces spores on a 24-hour cycle. According to the National Institute of General Medical Sciences, neurospora crassa, "is simple to grow and has features that make it very suitable for answering questions about how species arise and adapt, as well as how cells and tissues change their shape in different environments." Neurospora crassa is red and produces tiny filaments along the surface of bread. Rhizopus Stolonifer
:This common, fast-growing bacterium is a member of the phylum omycota and produces black mold. Rhizopus stolonifer is highly toxic and can destroy bread quickly by consuming nutrients found in the bread. This bacterium grows most rapidly at temperatures between 59 and 86 degrees F. Rhizopus stolonifer spores are generally abundant in the atmosphere, and the bacterium will grow very quickly on bread stored in a relatively humid environment.
Aspergillus
:This common bacterium grows on cheese, decayed fruit and bread. It begins its life green and later turns to shades of reddish-yellow, yellow or reddish-brown. Ideal growing temperature range for aspergillus is between 71.6 to 86 degrees F. This common bacterium grows quickly on bread kept in a moist atmosphere. Most aspergillus species are toxic to humans but some are common ingredients in pharmaceutical drugs.
