One of the four general catalytic methods used by serine proteases is catalysis by approximation.
What is serine proteases?Endo proteases come in several forms, including serine proteases. They are, nonetheless, quite common in both prokaryotes and eukaryotes. Protease A, a chymotrypsin-like protease from Stremptomyces griseus, has a primary sequence very different from chymotrypsin, but its overall tertiary structure is very similar to chymotrypsin.
The positions of the catalytic triad amino acids in the primary sequences of the protein are very similar, indicating that the genes for the proteins diverged from a common precursor gene. B. subtilisin, a serine protease, in contrast, Subtilis shares only a small amount of tertiary structural homology with chymotrypsin. But when folded, it also possesses a catalytic triad (Ser 221 - His 64 - Asp 32) akin to chymotrypsin's (Ser 195 - His 57 - Asp 102).

The heat of combustion for the unknown hydrocarbon when1 mole of an unknown hydrocarbon is burned in a bomb calorimeter and the Calorimeter increases in temperature by 12.19°C is -611.26kJ/mol
What is a bomb calorimeter?A device that is mostly used to measure combustion temperatures. The reaction occurs in a sealed area known as the calorimeter proper, in constant thermal contact with its surroundings (the jacket).
To calculate the heat of combustion we follow the given steps:
Heat released by the combustion =Cp×ΔT=1.929×12.19 kJ=23.51 kJ
Hence, ΔH=−23.51 kJ/g
A unknown hydrocarbon has an empirical formula of CH and a molar mass of 26 g/mol.
So, ΔH combustion=−23.51×26g /mol=−611.26kJ/mol
Hence, ΔH combustion=−15.6×180 kJ/mol=−611.26kJ/mol
ΔH combustion=−611.26kJ/mol
Hence, the heat of combustion for the unknown hydrocarbon when1 mole of an unknown hydrocarbon is burned in a bomb calorimeter and the Calorimeter increases in temperature by 12.19°C is -611.26kJ/mol

When the kinetic energy of an object changes, there must be some other change in energy at the same time?
When the kinetic energy of an object changes, the motion of that object also changes at the same time.
The amount of energy that a body posses by virtue of its motion is known as Kinetic energy. Therefore, kinetic energy can only be found in objects which are in motion. The amount of Kinetic energy is calculated as follows:
K = 1 /2 mv²
Where, K represents the kinetic energy, m is the mass of the moving object, and v is the velocity or the speed of the object at which it is moving.
If the kinetic energy of the body increases then the motion of the body also increases and if the kinetic energy decreases then the velocity also decreases.

question: methanol, ch4o, is finding use as a fuel additive. describe the effect of each of the following changes on the equilibrium mixture for the combustion of methanol: a. adding more co2(g) b. adding more o2(g) c. increasing the temperature d. adding a catalyst
On adding more CO2 equilibrium shifts to left, adding more oxygen the equilibrium shift to right, increasing a temperature will shift the equilibrium to left and adding the catalyst will not affect the equilibrium.
According to Heisenberg Uncertainty Principle, if the equilibrium of a system of reaction is disturbed by making any changes in the property the reaction will shift into that direction by itself that stabilizes the equilibrium again.
According to the reaction,
CH4O + O2 = H2O + CO2 + Heat
a. Adding more CO₂ will shift the reaction towards the left side or we can say that adding carbon dioxide into the system will shift the reaction towards the reactant side. Because the concentration of carbon dioxide on the product side has increased, the equilibrium is disturbed so in order to stabilize the equilibrium again the reaction will shift towards the reactant side.
b. Adding more oxygen means that we are adding more amount of reactants which disturbs the equilibrium of the reaction so to stabilize the equilibrium again the reaction will shift towards the product side.
c. Increasing the temperature of the equation means that we are giving heat to the system which means that the equation or the system will shift toward the product side because the reaction is exothermic in nature.
d. Adding a catalyst will not affect the equilibrium of the reaction it will only increase the rate of the reaction.

Phosphoric acid (orthophosphoric acid, monophosphoric acid, or phosphoric(V) acid) is a colourless, odorless phosphorus-containing solid and inorganic substance having the chemical formula H3PO4. It is most usually seen as an 85% aqueous solution, which is a colourless, odourless, non-volatile syrupy liquid. It is an important industrial chemical that is found in many fertilisers.
The compound is an acid. The phosphate ion PO 34 is formed when all three H+ ions are removed. The removal of one or two protons yields the dihydrogen phosphate ion H2PO - 4 and the hydrogen phosphate ion HPO 2 4, respectively. Phosphoric acid creates esters known as organophosphates.
The term "orthophosphoric acid" can be used to distinguish this acid from other "phosphoric acids," such as pyrophosphoric acid. Nonetheless, the word "phosphoric acid" refers to this particular molecule.

The molarity of a solution containing 104.2 grams of BaCl2 in enough water to make 800 ml of solution is 0.625mol/L.
What is molarity?
Molarity is one of the measures of the concentration in terms of the number of moles of the solute dissolved in particular volume of the solution.
Molarity of BaCl2 can be calculated by,
Molecular mass of BaCl2 is 208.23gmol^-1
Number of moles = mass / molecular mass = 104.2g / 208.23gmol^-1 = 0.50mol.
Molarity = Number of moles / volume = 0.50mol / 0.8L = 0.625mol/L.
