The water used is usually brackish water or brine (i.e. a solution with >0.5% salinity). In these cases, additional contaminant chemicals may be present in the water feed. The low voltage DC current still performs electrochlorination. The excess chemicals are left untouched and can be easily discarded. [2]
Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...
For example, if one tried to demonstrate it using the hydrocarbons decane (C 10 H 22) and undecane (C 11 H 24), one would find that 100 grams of carbon could react with 18.46 grams of hydrogen to produce decane or with 18.31 grams of hydrogen to produce undecane, for a ratio of hydrogen masses of 121:120, which is hardly a ratio of "small ...
Reaction stoichiometry describes the 2:1:2 ratio of hydrogen, oxygen, and water molecules in the above equation. The molar ratio allows for conversion between moles of one substance and moles of another. For example, in the reaction 2 CH 3 OH + 3 O 2 → 2 CO 2 + 4 H 2 O. the amount of water that will be produced by the combustion of 0.27 moles ...
The reaction also occurs in the gas phase, in the presence of a phosphoric acid salt as a catalyst. [33] The reaction is usually carried out at about 60 °C (140 °F) with a large excess of water, in order to prevent the reaction of the formed ethylene glycol with ethylene oxide that would form di-and triethylene glycol: [34]
Standard enthalpy of combustion is the enthalpy change when one mole of an organic compound reacts with molecular oxygen (O 2) to form carbon dioxide and liquid water. For example, the standard enthalpy of combustion of ethane gas refers to the reaction C 2 H 6 (g) + (7/2) O 2 (g) → 2 CO 2 (g) + 3 H 2 O (l).
In organic chemistry, the Nef reaction is an organic reaction describing the acid hydrolysis of a salt of a primary or secondary nitroalkane (R−NO 2) to an aldehyde (R−CH=O) or a ketone (R 2 C=O) and nitrous oxide (N 2 O). The reaction has been the subject of several literature reviews. [1] [2] [3] The Nef reaction: 1. Salt of a nitroalkane ...
The Fischer–Tropsch process involves a series of chemical reactions that produce a variety of hydrocarbons, ideally having the formula (C n H 2n+2). The more useful reactions produce alkanes as follows: [7] (2n + 1) H 2 + n CO → C n H 2n+2 + n H 2 O. where n is typically 10–20. The formation of methane (n = 1) is unwanted.
