Downloadable content (DLC) [a] is additional content created for an already released video game, distributed through the Internet by the game's publisher. It can either be added for no extra cost or it can be a form of video game monetization, [1] enabling the publisher to gain additional revenue from a title after it has been purchased, often using some type of microtransaction system.
Having started with only diamond and oxygen, and produced a gas which contains only carbon and oxygen, Tennant had discovered that diamonds are made of carbon. Unaware of atomic theory at the time, scientists were unable to explain how carbon, already known to exist as one of the softest substances in the form of graphite , could also be the ...
Carbon is the sixth element, with a ground-state electron configuration of 1s 2 2s 2 2p 2, of which the four outer electrons are valence electrons. Its first four ionisation energies, 1086.5, 2352.6, 4620.5 and 6222.7 kJ/mol, are much higher than those of the heavier group-14 elements.
Directly observational data is in red, with all data showing a 5 year moving average. [43] Climate change is largely driven by the release of greenhouse gases like CO 2, and the burning of fossil fuels is the main source of these emissions. In most parts of the world climate change is negatively impacting ecosystems. [44]
The world's first coal-fired power plant designed to capture and store carbon dioxide that it produces began operations in Spremberg, Germany. Built alongside the 1,600MW Schwarze Pumpe power plant in north Germany, the demonstration experiment will capture up to 100,000 tonnes of CO 2 a year, compress it and bury it 3,000m below the surface of ...
These included carbon dioxide and carbon monoxide. The emissions probably did not include methane, but the Earth was probably free of molecular oxygen. The Late Heavy Bombardment was between 4.0 and 3.8 billion years ago (Ga). To start with, the Earth did not have a crust as it does today. Plate tectonics in its present form commenced about 2.5 ...
Carbon dioxide is a chemical compound with the chemical formula CO 2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is odorless.
Carbon dioxide is also produced and released during the calcination of limestone for clinker production. [115] Clinker is an industrial precursor of cement. As of 2020, about 450 gigatons of fossil carbon have been extracted in total; an amount approaching the carbon contained in all of Earth's living terrestrial biomass. [114]
