![]() Sometimes there may be multiple compounds with that element on one side, so you'll need to use your best judgement and be prepared to go back and try the other options. What is the preferred name for Mg3N2 Magnesium Nitride. In the periodic table of elements, its number 12, and placed in the earth alkali group. The group 7A element astatine (85At) would be predict to occur in what phrase Solid. Step 2: Multiply coefficients for compounds to balance out each elementįor each element that is not equal, try to balance it by adding more of it to the side with less. Mg is the chemical symbol for the atomic element Magnesium. Step 1: Count the number of each element on the left and right hand sides When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced. To be balanced, every element in N2 + Mg = Mg3N2 must have the same number of atoms on each side of the equation. ![]() Since there are an equal number of atoms of each element on both sides, the equation is balanced. ![]() The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. Answer and Explanation: 1 Mg 3 N 2 is the formula for the chemical compound magnesium nitride. Step 3: Verify that the equation is balanced. Magnesium nitride, which possesses the chemical formula Mg 3 N 2, is an inorganic compound of magnesium and nitrogen. Balanced Chemical Equation N2 + 3Mg Mg3N2 Scroll down to see reaction info and a step-by-step answer, or balance another equation. ![]()
