An unknown element, X, reacts with sodium to form the compound Na2X. In other compounds, this element also can accommodate up to 12 electrons rather than the usual octet. What element could X be? A. S Elements in the same group ...
These elements are shiny and silver-white as pure metals, although they usually appear dull because they react with air to form surface oxide layers. All the alkaline earths, except forberyllium, form corrosive alkaline hydroxides. All of the alkaline earths react with halogens to form halides. ...

However, what critics of the male gaze may wonder is why do they want to pose and dress in this manner? Maybe it's just for fun, or to experiment with their burgeoning sexuality or identity or trying on a role. But what is the underlying motivation? Who are they dressing for? Who is...
Titration is a quantitative chemical analysis that adds a solution to the sample. The titrant will contain a known chemical that reacts with the substance for which the assay is being done. Gravimetric analysis is the most commonly used wet method. The material is precipitated, filtered, washed...
A replacement reaction is a type of chemical reaction in which one element replaces another in a compound. This can either be in the form of a single replacement reaction or a double replacement reaction. In a single replacement reaction, one of the reactants is more reactive than the other...
