Respuesta :
When metal A is added to acid, bubbles of H 2 start to develop. The reason for this is that metal A is more reactive than metal B.
write a short note on hydrogen and its behavior.
The chemical element hydrogen is represented by the letter H and atomic number 1. The lightest element is hydrogen. Under normal circumstances, hydrogen is a gas made up of diatomic molecules with the formula H2. It is non-toxic, tasteless, colorless, odorless, and highly combustible. In the cosmos, hydrogen is the most prevalent chemical, making up around 75% of all ordinary matter. Plasma hydrogen makes up the majority of stars like the Sun. On Earth, hydrogen mostly takes the form of molecules like water and organic substances. Each atom of hydrogen's most prevalent isotope, 1H, has one proton, one electron, and no neutrons.
Why does H2 have such a low reactivity?
The nonpolar character of H 2 and its weak polarizability serves as the kinetic basis for the low reactivity. Hydrogen chloride and hydrogen fluoride are the products of their spontaneous reactions with fluorine and chlorine, respectively. Metal catalysts have a significant impact on the reactivity of H 2.
