The molar concentration of a solution, usually expressed as the number of moles of solute per liter of solution.
It’s a convergent boundary which means they are sliding
Enzymes are highly reaction-specific. An enzyme is a catalyst, meaning they greatly increase the rate of reaction. However, they only work in very specific reactions, which they are tailored for.
The exterior of magnesium metal is shielded with a thin layer of oxide that somewhat protects the metal from attack by air. Magnesium metal burns in air with a distinctive blinding bright white spark when ignited to give a mixture of white magnesium oxide, MgO, and magnesium nitride, Mg3N2. Magnesium is highly reactive to halogens such as chlorine, Cl2 or bromine, Br2, and it burns to create dihalides magnesium chloride, MgCl2 and magnesium bromide.
