Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water acts as a plasticizer.
The "h3h3" name was created in reference to the couple's first initials. However, because "hehe" was not an available title, they opted for "h3h3." [10] The h3h3Productions YouTube channel first got mainstream traction when Klein began posting weekly reaction videos. These videos were in response to what he describes as left-leaning "social ...
The integral heat of dissolution is defined as a process of obtaining a certain amount of solution with a final concentration. The enthalpy change in this process, normalized by the mole number of solute, is evaluated as the molar integral heat of dissolution. Mathematically, the molar integral heat of dissolution is denoted as
A catalyst is required to make the process operate at feasible temperatures. Heating the water can be achieved through the use of water concentrating solar power. Hydrosol-2 is a 100-kilowatt pilot plant at the Plataforma Solar de Almería in Spain which uses sunlight to obtain the required 800 to 1,200 °C to heat water. Hydrosol II has been ...
h3h3Productions is a YouTube channel launched in 2011 by Ethan and Hila Klein, an American and Israeli husband and wife duo. [3] The primary format of videos uploaded to the channel involve the Kleins' critique and commentary reaction videos, with clips of a source video intermixed with commentary and absurd, a style which has been described as a cross between the works of comedy duo Tim ...
Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.
Therefore, hydrogen molecules effuse four times faster than those of oxygen. [1] Graham's law can also be used to find the approximate molecular weight of a gas if one gas is a known species, and if there is a specific ratio between the rates of two gases (such as in the previous example). The equation can be solved for the unknown molecular ...
Electrolysis of pure water requires excess energy in the form of overpotential to overcome various activation barriers. Without the excess energy, electrolysis occurs slowly or not at all. This is in part due to the limited self-ionization of water. Pure water has an electrical conductivity about one hundred thousandth that of seawater. [8] [9 ...
