120 KJ of heat is absorbed in this reaction.
As we know
Where W is the provided mass of carbon, which is 30g, n=W/M
M is the carbon molar mass. 30 / 12 = 2.5 moles at 12g/mol.
As a result, the heat absorbed by 2.5 moles of carbon is equal to 120 kJ, or half the heat absorbed by 5 moles of carbon, or 239.9 kJ.
The heat evolved (either emitted or absorbed) during a process that runs at constant pressure is equivalent to the change in enthalpy. The internal energy (U) and pressure-volume product (PV), are both supplied by the equation:

describe how infrared spectroscopy could be used to determine when the addition of br2 to 1-pentene had gone to completion.
Infrared spectroscopy is the analysis of infrared light interacting with a molecule. It is widely used to detect presence of functional groups and multiple bonds in organic and inorganic molecules.
There is a characterstic region of light in the absorption spectra of each compound which serves as its fingerprint. Most functional groups show absorption bands in the region (400-1400cm^-1), so it can be used to detect their presence in the molecule.
To determine whether or not the addition reaction of Bromine (Br2) with 1-pentene has gone to completion , this technique can be used as the C-H sp2 and C=C bonds spectral bands will disappear.

why does venus have the largest gravitational attraction of the inner planets?
Venus is the second planet from the Sun and is named after the Roman goddess of love and beauty.
Why does Venus have the largest gravitational attraction of the inner planets?Venus has much lower mass as compared to other planets. The distance between the Earth and Venus is much shorter as compared to the distance between Earth and Jupiter. Similarly, the gravitational force of each of these planets on objects on the surface of Earth is largest for Jupiter.
The radius of Venus is 4.6023×108 km2, the mass of Venus is 4.8675×1024 kg, and has a density of 5.243 g/cm3 so that's why Venus is equivalent in size, mass and density of the Earth. So that's why the gravity on Venus is very close to that of Earth.

How many electrons are transferred from glyceraldeyde 3 phosphate to nad in glycolysis?
Electrons transferred from Glyceraldehyde 3 phosphate to NAD in glycolysis per glucose are 4.
What are electrons?The electron is a subatomic particle (denoted by symbol e−or β−) whose electric charge is negative one elementary charge. Electrons belong to first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1836 times smaller than that of proton.
Quantum mechanical properties of electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can occupy same quantum state, in accordance with the Pauli exclusion principle. Like all elementary particles, electrons exhibit properties of both the particles and waves: They can collide with the other particles and can be diffracted like light. The wave properties of electrons are easier to observe with the experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for given energy.
Electrons play an essential role in numerous physical phenomena, such as electricity, magnetism, chemistry and thermal conductivity, and they also participate in the gravitational, electromagnetic and weak interactions. Since an electron has charge, it has a surrounding the electric field, and if that electron is moving relative to an observer, said observer will observe it to generate a magnetic field. Electromagnetic fields produced from other sources will affect the motion of an electron according to Lorentz force law.
Electrons radiate or absorb energy in form of photons when they are accelerated. Laboratory instruments are capable of trapping individual electrons as well as electron plasma by use of electromagnetic fields. Special telescopes can detect the electron plasma in outer space. Electrons are involved in many applications such as the tribology or frictional charging, electrolysis, electrochemistry, battery technologies, electronics, welding, cathode-ray tubes, photoelectricity, photovoltaic solar panels, electron microscopes, radiation therapy, lasers, gaseous ionization detectors and particle accelerators.

To make the spot more rounder, add a trace of acetic or formic acid to the eluting solvent mixture.
Thin layer chromatography:Thin layer chromatography (TLC) is a chromatographic method that uses a thin stationary phase supported by an inert backing to separate the components of a mixture. It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical.
Like all chromatography, TLC works on the principle that a chemical will have varying affinities for the mobile and stationary phases, influencing how quickly it migrates. TLC aims to produce well-defined, well-separated spots.
Streaks rather than spots are frequently produced in neutral solvents by acids, bases, and highly polar substances. Streaks can obscure other areas and make it challenging to compute a [tex]R_{f}[/tex].
Acid streaking can be corrected by adding a few percent of acetic or formic acid to the solvent. Similarly for bases, adding a little amount of triethylamine can enhance results. Adding a little amount of methanol can enhance polar substances' results.

A scientific method for dissolving a mixture into its constituent parts is chromatography.the chromatographic procedure of removing an adsorbate from a solid adsorbing media called elute using a solvent. separating an antibody from the antigen it is bound to.In reverse phase liquid chromatography, stationary phase is non-polar in nature and becomes more non-polar as the number of carbon chains grows.The order of elution from a column usually follows the series: alkyl halides < saturated hydrocarbons < unsaturated hydrocarbons < ethers < esters < ketones < amines < alcohols < phenols < acidsare typically eluted from columns in the following order. Salts and polymeric substances frequently do not elute. Solvents: For adsorbent sites, the solvent will compete with the sample.The more polar the solute, the more readily it will dissolve in the stationary phase, remain in the column, and finally elute last. Therefore, in normal phase chromatography, the non-polar component will elute earlier than the polar component between the polar and non-polar components.4-hydroxynitrobenzene is more polar than 2-hydroxynitrobenzene therefore it will elute last.

To determine the standard heat of formation for carbonic acid, h2co3, the proper chemical equation is:_________
The standard heat of formation for carbonic acid, H₂CO₃, the right chemical equation is H₂CO₃ → H₂O + CO₂ (and also H+ and CO₃— but this is irrelevant here).
Carbonic acid reaction :An important example of a reversible reaction in the human body.
This reaction occurs when CO₂ (CO₂) and water (H₂O) combine to form carbonic acid (H₂CO₃).
The newly formed acid is unstable, and it dissociates to yield both proton (H+) and bicarbonate ion (HCO₃-). The equation for the entire carbonic acid reaction is: H₂CO₃ → H₂O + CO₂
Carbonic acid (H₂CO₃) forms in small amounts when CO₂ dissolves in H₂O, yet decomposes rapidly under ambient conditions of temperature and pressure. Despite its fleeting existence, H₂CO₃ plays a crucial role in the global carbon cycle and in biological carbonate-containing systems. The short lifetime in water and presumed low concentration under all terrestrial conditions has stifled study of this fundamental species.

Net Ionic chemicals do not all dissolve in water.
What mix of ions will dissolve is determined by a list of solubility rules.
In a precipitation reaction, soluble reactants are transformed into one or more insoluble product(s). The precipitate is the term for the material. Example: When LiCl and AgNO3, both of which are soluble, are combined, the result is AgCl, which is insoluble.
[tex]AgNO_{3} (aq) + LiCl(aq) -- > AgCl(s) + LiNO_{3} (aq)[/tex]
