Carbonation


This article is about carbonation reactions in chemistry. For carbonated beverages, see Soft drink § Carbonated drinks, and Carbonated water.

Carbonation refers to reactions of carbon dioxide to give carbonates, bicarbonates, and carbonic acid.[1] In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids.


In inorganic chemistry and geology, carbonation is common. Metal hydroxides (MOH) and metal oxides (M'O) react with CO2 to give bicarbonates and carbonates:


MOH + CO2 → M(HCO3)

M'O + CO2 → M'CO3

In reinforced concrete construction, the chemical reaction between carbon dioxide in the air and calcium hydroxide and hydrated calcium silicate in the concrete is known as neutralisation.



Henry's law


Henry's law states that PCO2=KBxCO2 Where PCO2 is the partial pressure of CO2 gas above the solution. KB is Henry's law constant. KB increases as temperature increases. xCO2 is the mole fraction of CO2 gas in the solution. According to Henry's law carbonation increases in a solution as temperature decreases.[2]

Node.js Script on GitHub Pages or Amazon S3

圖片
0 I'm wondering if I can run a Node.js script in my Jekyll page from GitHub Pages or Amazon S3? I think it can't run on GitHub Pages since it doesn't support server side code. Not too sure. The code is below: var Airtable = require('airtable'); var base = new Airtable(apiKey: 'YOUR_API_KEY').base('appAnZVyYqusNPV5Q'); base('Invitee list').select( // Selecting the first 3 records in Complete list: maxRecords: 3, view: "Complete list" ).eachPage(function page(records, fetchNextPage) // This function (`page`) will get called for each page of records. records.forEach(function(record) console.log('Retrieved', record.get('Email')); ); // To fetch the next page of records, call `fetchNextPage`. // If there are more records, `page` will get called again. // If there are no more records, `done` will get called. fetchNextPage(); , function done(err) if (err) console.error(err); return; ); node.js
