Explain why calcium is generally more reactive than magnesium. Why do hydrogen atoms emit or absorb only discrete amounts of energy? Explain why even if a chemical reaction has a yield close to 100%, the atom economy may be poor.
Suggest why the melting temperature of magnesium oxide is higher than that of magnesium chloride, even though both are almost 100% ionic. Why are cast iron and steel used a lot more than pure iron? Why does salt cause ice to melt?
Also, magnesium deficiency may increase inflammatory factors like C-reactive protein which helps the development of depression [40]. A healthy diet and lifestyle could affect symptoms of mood disorder in recovered COVID-19 patients [5, 41]. Inflammation caused by COVID-19 can affect neurological...
Acetaldehyde is a reactive com- pound that is highly toxic to hepatocytes because it can sensitize cells to oxidative stress or other damaging signals, ultimately leading to mitochondrial damage and cell death2,19. At the basal level, hepatic acetaldehyde level was increased by 2.2 fold in Ces...

Explain why the following is incorrect. Nickel will react with a HCl solution but not with steam to produce hydrogen and nickel ion solution. Magnesium will react with steam to produce hydrogen and magnesium ions. Therefore, nickel is more reactive than m ...
use of a starch indicator to increase the sensitivity of iodometric titration to produce a more visible color change. Complexometric indicators include the chelating agent EDTA, which is used to titrate metal ions in solution, and Eriochrome Black T for the titration of calcium and magnesium ions....
Research on both animals and humans indicates that inhaled titanium dioxide remains inert. Fibrosis linked to titanium exposure is more likely due to other elements found in titanium dust rather than titanium dioxide itself. In animals, titanium nitrides, titanium hydrides, and titanium carbides have ...
Is magnesium malleable or brittle? Is nihonium malleable? Is californium a metal? Is deuterium an element? What is magnesium's state of matter? Is deuterium more reactive than hydrogen? Is hydrogen a positive or negative ion? Does metallic bonding conduct electricity? Are metals or nonmetals duc...
(a) Would magnesium react with dilute sulfuric acid? (b) Why or why not? Why does the reaction of Mg and HCl produce heat and vapour? Besides hydrogen being produced in the form of bubbles. Is water flammable? Explain why or why not. ...
