The Michaelis–Menten equation is an expression of the relationship between the initial velocity ????0 of an enzymatic reaction a

nd substrate concentration [S] . There are three conditions that are useful for simplifying the Michaelis–Menten equation to an expression from which the effect of [S] on the rate can be more readily determined. Match the condition (e.g., [S]=Km ) with the statement or statements that describe it.
(1) Doubling [S] will almost double the rate.
(2) Half of the active sites are occupied by substrate.
(3) About 90% of the active sites are occupied by substrate.
(4) Doubling [S] will have little effect on the rate.
(5) Less than 10% of the active sites are occupied by substrate.
(6) This condition will result in the highest rate.

The coordination compound Co3[Cr(CN)6]2 contains Co2+ cations and a complex anion. What is the likely oxidation state for Cr in
otez555 [7]

Answer:

-3

Explanation:

The oxidation state or oxidation number of an atom is the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.

The complex anion here is [Cr(CN)6]3-.

Now, as the oxidation state of CN or cyanide ligand is -1, and if we suppose the oxidation state of Cr to be 'x', then; x - 6 = -3 (overall charge on the anion),

so x= +3. Hence the oxidation state of Chromium in this complex hexacyanochromium (III) anion comes out to be -3.

Carbondioxide gas is't collectable in water. why​?
Lisa [10]

Answer:

carbon dioxide is a gas so it isn't collected over water.

Explanation:

it works for insoluble gases such as hydrogen,or gases that do not dissolve easily in water such as ammonia and chlorine are readily soluble in water and are not collected this way.

hope it is helpful for you.

During the process of heat transfer, the heat transferred to or from a system's surroundings is always?
OleMash [197]

Answer:

During the process of heat transfer, the heat transferred to or from a system's surroundings is always equal in magnitude to the heat transferred to or from the system, but opposite in sign.

<h2>What is the 1st law of thermodynamics?</h2>

The total energy of an isolated system is said to stay constant according to the first rule of thermodynamics. Energy cannot be generated or destroyed, but it may be transformed from one form into another inside a closed system, which is known as the conservation of energy.

This rule states that when a system is exposed to a certain amount of heat, the amount of heat that the system absorbs is equal to the product of the increase in internal energy (change in internal energy) of the system and the external work that the system does. The relationship between a system's internal energy and work output and the heat given to it is demonstrated by the first law of thermodynamics. This equation provides the foundation for the majority of practical innovations like heat engines, freezers, and air conditioners.

The equation for the first law of thermodynamics is given as; ΔU = q + W

Where,

  • ΔU = change in internal energy of the system.
  • q = algebraic sum of heat transfer between system and surroundings.
  • W = work interaction of the system with its surroundings.

The heat transported to or from a system's surroundings during the process of heat transfer is always opposite in sign, but equal in size, to the heat transferred to or from the system.

What is heat transfer?

       The flow of thermal energy between physical systems is known as heat transfer. The temperatures of the systems and the characteristics of the medium used to transmit the heat affect how quickly it transfers. Conduction, convection, and radiation are the three basic ways that heat is transferred. It is crucial to employ heat transfer, or the movement of energy in the form of heat, in applications of the First Law of Thermodynamics since it is a mechanism through which a system changes its internal energy. Diffusion and conduction are two different concepts. Diffusion linked to fluid mixing is not the same as conduction.

    The Second Law of Thermodynamics controls the direction of heat transmission, which is from one area of high temperature to another area of lower temperature. The internal energy of the systems from and to which the energy is transmitted is altered during heat transfer. Heat transfer will take place in a way that makes the group of systems' entropy higher.

   In physics, heat is described as the flow of thermal energy over a boundary that is clearly defined surrounding a thermodynamic system. The amount of work that a thermodynamic system may accomplish is known as the thermodynamic free energy. Enthalpy is a thermodynamic potential with the letter "H" that is made up of the system's internal energy (U) plus the volumetric product of pressure (P) and temperature (T) (V). A joule is a unit used to measure energy, effort, or heat production.

  The quantity of heat transmitted in a thermodynamic process that modifies a system's state relies on how that process happens, not just the net difference between the process' beginning and ending states, since heat transfer is a process function (or route function), as opposed to a function of state.

 The heat transfer coefficient, which represents the relationship between the heat flux and the thermodynamic force that drives the flow of heat, is used to determine both thermodynamic and mechanical heat transfer. A quantitative, vectorial description of the movement of heat through a surface is called a heat flux.

     The term "heat" is sometimes used interchangeably with "thermal energy" in technical applications. This usage derives from the historical understanding of heat as a fluid (caloric) that may be transported by a variety of reasons, which is also prevalent in laypeople's language and daily life.
