How big is proton?4 answersThe size of the proton has been a topic of debate in recent years. Traditional measurements using electron scattering and precision spectroscopy of hydrogen have provided a low precision estimate of the proton's charge radius. However, recent experiments using laser spectroscopy of muonic hydrogen, where a muon replaces the electron, have yielded a more precise value for the proton's charge radius. This new measurement differs significantly from the accepted value and has sparked discussions about the "proton size puzzle". Additionally, precise measurements of the 1S-2S transition in regular hydrogen have also contributed to improved values of the Rydberg constant. The discrepancy between measurements of regular hydrogen and muonic hydrogen has puzzled physicists, and efforts are underway to understand the sources of systematic errors and reconcile the different results.

What are the effects of H3PO4 and NaOH on the activation of carbon?5 answersH3PO4 and NaOH have significant effects on the activation of carbon. H3PO4/KOH combined solution is proposed as an effective activation agent for producing activated carbon from rice husk. The mixed agent partially decomposes the chemical compounds on the rice husk char surface, resulting in an increase in surface area. The presence of a considerable amount of amorphous silica is observed in the activated carbon produced using the combined solution. Electrochemical measurements show that the volume of the activation agent solution should be optimized for both single and mixed activation agents. N-doped carbons are carbonized in the presence of H3PO4 and NaOH additives, resulting in an increase in char yield. Acid-treated chars contain a dominant pyrrolic N form, while NaOH-treated chars are richer in pyridinic structures. Activated carbon prepared by H3PO4 treatment shows increased oxygen content and decreased graphitization degree, leading to higher reactivity towards oxidation and reverse Boudouard reactions. Phosphoric acid is used for chemical impregnation and activation of activated powdered carbon (APC), resulting in higher specific surface area and better pore distribution.
How does the ionic radius of group 2 hydroxides affect their solubility in acid?5 answersThe solubility of group 2 hydroxides in acid is influenced by the ionic radius of the metal cation. Larger atomic radii result in greater solubility. The solubility products for rare earth hydroxides also show greater solubility for larger atomic radii. In the case of zirconium hydroxide, the solubility is affected by the size of the amorphous primary particles and crystallized large particles, as well as their surface configuration. The hierarchical structure of zirconium hydroxide, which includes tetrameric and dimeric hydroxide species, influences its solubility in aqueous solutions. However, the specific influence of the ionic radius of group 2 hydroxides on their solubility in acid was not directly addressed in the provided abstracts.
How many percent P inH3PO4?2 answersPhosphorus (P) availability is low in many natural systems and cropping systems, unless applied as fertilizer. The abstract does not provide information about the percentage of P in H3PO4.
What is h3po4?3 answersH3PO4 is phosphoric acid, which is used as an activator in the production of carbon-based materials such as activated carbon and solid acid catalysts. It is commonly used in the activation process of biomass materials like sugarcane bagasse and wood to create activated carbon with high surface areas and porosity. Phosphoric acid is also used in the modification of materials like titanium dioxide to enhance the properties of activated carbon. In addition, phosphoric acid is used in the production of phosphated niobia catalysts, which have higher esterification activity. Furthermore, phosphoric acid-based geopolymers, which have low dielectric properties, can be used as encapsulating materials.
