However, several reactions benefit from use of a catalytic material that lowers the activation energy of the reaction without being consumed during the reaction. Several types of catalyst have been developed for the synthesis of phosphonates. Below, some of the most common ones found in the ...
what is SO4 and why does it have a charge of -2? A small amount of liquid bromine is added to a container which is then sealed. Using the ideas of kinetic energy, can you explain why after one hour the bromine molecules have spread uniformly to occu ...
Nucleophiles have a negative charge. Explain, in terms of the polarity of the bonds in an alcohol, which carbon in CH3CH2OH the nucleophile would be attracted to. In addition, explain why, in terms of t Draw the major product(s) from the addition of HBr to the alkene below. What ...
It is also defined as the charge of an ion. The oxidation number is used in REDOX reactions. In those reactions, we determine the oxidation state of each atom to predict if it is going to oxidize or to reduce. Answer and Explanation: ...
MSC-based strategies are attractive because compared to chondrocytes, bone marrow MSCs have the advantage of ease of access, thereby eliminating the need for a first operation, and the greater number of cells obtained during the isolation and following expansion without the risk of de-differentiation...
Disodium Laureth Sulfosuccinate is a larger molecule derived fromcoconut. The molecule itself has nosulfate ion sulfate ion Sulfate, SO42−, in organic chemistry,a salt of sulfuric acid. ... SO4 is an acronym for remembering the function of the fourth cranial nerve, the trochlear nerve, whic...
but I have wondered what processes the Mg is undergoing during the charge/discharge process, and if it would return so cleanly into MgSO4 under discharge, or if, instead, it would remain as Mg(OH)2, and the SO4 ion from the PbSO4 would react with the water, to form HSO4- ions?--...
It does not conduct electricity, as there are no electrons free to move and carry charge. It has a high melting point and boiling point as much energy is needed

(12分)如图所示，质量为M的小球被一根长为L=0.7米的可绕O轴自由转动的轻质杆固定在其端点，同时又通过绳跨过光滑定滑轮与质量为m的小球相连．若将质量为M="3" m的球由杆呈水平状态开始释放，不计摩擦，竖直绳足够长，则当杆转动到竖直位置时，质量为m的球的速度是多大？g=10m/s 2 ...
