Ion chromate formule
WebCoulomb's Law is a mathematical formula that describes the electrostatic interaction between two charges particles that was first proposed by the French physicist Charles Coulomb (1736–1806). Coulomb's law is often called an inverse square law, as the force decreases as a function of the square of the distance between the two particles. Web7 apr. 2024 · Also, chromate has a molecular weight of 194.18 g/mol. Now let us look at the chromate formula or chromate anion formula.
