S (reaction) = 2.70 + 1.205 - 2,109.6 ,S ° (reaction) = 125.8 J / mol K

Entropy (S, abbreviated as entropy) in thermodynamics represented the degree of system disorder.

Entropy, like other thermodynamic concepts, can only be determined from the beginning and ending states.

Then energy is converted into different forms, entropy will also change.

Standard entropy data allow for the calculation of S °'s value.

The formula is S ° (reaction) = S ° (product) - S ° (reagent)

The standard thermodynamic quantities for chemical substances at 25 °C for entropy can be found in the CRC Handbook of Chemistry and Physics data table, 84th Edition (2004) as follows: (Supporting evidence can be found in other data.)

NH3 (g) = 192.8 J/mol K.

O2 (g) = 205 J per mole of K

Water (g) = 188.8 J/mol K

H2O (mol) = 70 J/mol K

NO2 (g)=240.1 J/mol K

The most stable contributor's structure is the genuine structure of the resonance hybrid. The delocalization of electrons is what stabilizes the resonance hybrid. The potential resonance forms are quickly interconverted by a resonance hybrid.

Equivalent resonance types equally contribute to the hybrid's overall structure. Consider the resonance hybrid structure of a carboxylate group as an example. Different resonance contributors do not always contribute equally to the hybrid structure until they are equivalent to one another in terms of stability, as is the case for the carboxylate group, which has equivalent contributions from A and B as shown in the given figure. One resonance structure will more closely resemble the “actual” (hybrid) structure than another if it is more stable (lower in energy) than the other.

Answer:

6.55 g

Explanation:

The atomic mass of Carbon (C) is 12.0107, of Hydrogen (H) is 1.008, of Nitrogen(N) is 14.0067, and of Oxygen(O) is 15.9994

Therefore the molar mass of acetaminophen = 12.0107 + 4 * 1.008 + 14.0067 + 2 * 15.9994 = 151.16

mass of C in 99.0 g of acetaminophen = (99.0 g / 151.16 g/mol) * 1 mol C/ 1mol acetaminophen

In a compound, covalent bond type of bond is the sharing of electrons between adjacent atoms.

A covalent bond is a type of chemical bond formed by the sharing of one or more pairs of electrons between two atoms and compound. In a covalent bond, the shared electrons are located in the region between the nuclei of the two atoms, and the bond results in a lower energy state for the atoms involved. Covalent bonds are formed between atoms that have similar electronegativities, meaning they have a similar attraction for electrons. They are typically formed between non-metal atoms such as carbon, hydrogen, oxygen, and nitrogen. Covalent bonds can be single, double or triple depending on the number of electrons shared between the atoms.

The percent yield of the reaction of H2O2 is found to be 21.16%

The theoretical yield is the yield that is obtained using a balanced chemical reaction. What you actually obtain in a chemical reaction is the actual yield. The actual yield is evaluated with the theoretical yield to establish the percent yield.

2 H2O2 => 2H2O + O2

78.2 mL of 4.6 M solution of H2O2 :

=> 78.2/1000*4.8= 0.359 mole H2O2

2 moles H2O2 ---> 1 mole O2

=> 0.359 moles H2O2-----> x mole O2

 x  => 0.359/2= 0.1795mole O2

Mendel contemplated two other theories for how two characteristics might diverge during gamete formation:

1. According to the blending theory, when two people with distinct qualities unite, the resultant offspring will combine both traits in an equal amount. For instance, the offspring of a red-flowered plant and a white-flowered plant will produce pink flowers.

2. According to this idea, genes are small, discrete units (particles) that when two people with different traits mate, their kids will either inherit one or the other trait. For instance, the child of a red-flowered plant and a white-flowered plant will have either red or white flowers, but not both.

Mendel experimented on pea plants to verify these theories. He crossed plants that were true-breeding for various qualities, such as tall plants with small plants and purple-flowered plants with white-flowered plants, and he looked at the inheritance patterns in the progeny. He discovered that his results supported the particulate hypothesis because the qualities were inherited in a predictable, Mendelian manner (i.e. dominant and recessive genes). His data did not support the blending theory because the kids did not exhibit a blend of both features.
