2016年1月12日 · Magnesium reacts with nitrogen to form magnesium nitride. The chemical formula for this reaction is #Mg+N_2-> MgN_2#.

2015年10月30日 · The correct formula for the Magnesium Nitrogen compound is Mg_3N_2. Magnesium has two valence electrons, and Nitrogen has five valence electrons.

2016年4月28日 · Mg_3N_2 Of course this is the ionic salt of Mg^(2+) and N^(3-). Hydrolysis gives ammonia: Mg_3N_2(s) + 6H_2O(l) rarr 3Mg(OH)_2(aq) + 2NH_3(aq)

2018年3月3日 · "Mg"_ 3"N"_2(s) + 6"H"_2 "O"(l) -> 3"Mg"("OH")_2(aq) + 2"NH"_3(aq) Now, the first thing is to monitor each element as an individual and count the number of moles present in each on the left side and equate it to exactly the same number of moles to the same element on the right side. For example, we have "Mg"_3"N"_2 on the left side and on the right side on the original equation we see ...

2017年11月17日 · And if we make magnesium nitride.... #3Mg(s) + N_2(g) stackrel(Delta)rarrMg_3N_2#...this represents a redox reaction....magnesium is oxidized, and dinitrogen is ...

2018年6月16日 · See below 3Mg(s)+N_2(g)=Mg_3N_2(s) First check that the equation is balanced. In this case, it is. Assuming that magnesium is the limiting reactant: First find the molecular weight using the Periodic Table. We find that the atomic mass of magnesium is approximately 24.3g, so the molecular weight is just (24.3g)/(mol) Next we need the mole to mole ratio. As there are 3 magnesiums for 1 ...

2014年5月5日 · Magnesium Nitrate is an ionic compound formed by Magnesium Mg^+2 the cation and Nitrate NO_3^- the polyatomic anion. In order for these two ions to bond the charges must be equal and opposite. Therefore, it will take two -1 nitrate ions to balance the one +2 magnesium ion. This will make the formula for Magnesium Nitrate Mg(NO_3)_2. I hope this was helpful. SMARTERTEACHER

2015年12月28日 · In 100 g of compound there are 72.2 g magnesium, and 27.8 g nitrogen. We divide thru by the molar masses of each element:
