Oct 16, 2024 · I was told that to determine the product of $\\ce{Mg + O2}$, you find the most simplified and neutral molecule the given reactants could form, being $\\ce{MgO}$. While I know there is a balanced vers...

Aug 20, 2022 · Some of the research there lead to an older German product called Hämozon, which does make reference to "Magnesium superoxide" and MgO2, but supposedly the formula has since been expanded upon. Any ideas?

Mar 30, 2013 · $\\ce{Mg + O2 → MgO}$ Magnesium, oxygen and magnesium oxide form the above equation. How? What do I need to learn to do this? atomic numbers/ valencies?

Oct 5, 2017 · So on an exam paper they have said to find out the enthalpy of formation for MgO is : ∆H = 148 + 736 + 1450 + 496/2 - 141 + 798 – 3791 = –552 kJ mol–1 , however if you draw out the born habor cycl...

Apr 21, 2014 · You are trying to find out the enthalpy of formation. The enthalpy of formation is the energy change when one mole of a substance is formed from its constituent elements in their standard state. The last equation matches this, so that should be your 'main' or 'target' equation. From there you should be able to use Hess' law to calculate the enthalpy change of the …

Oct 13, 2015 · Thus thermodynamics is not the reason and thus kinetics must be to blame. For starters combusted magnesium is going to produce partially amorphous MgO M g O which will reduce the activation energy to hydrolyze magnesium oxide, but why is it that solid magnesium oxide reacts slowly with water allowing me to use crucibles made of the stuff, while calcium …

Dec 24, 2019 · The decomposition of H2O2 is complex and has been the source of several studies. On iron oxide surface, here is a `Catalytic Decomposition of Hydrogen Peroxide on Iron Oxide: Kinetics, Mechanism, and Implications’. Some selected quotes: "As depicted in Figure 2, the decomposition rate of H2O2 appears to be independent of the goethite particle size. On …

Mar 16, 2015 · Background research Magnesium hydroxide exists naturally as brucite (source: wiki) Passing hot steam over magnesium produces magnesium oxide (source: Edexcel's June 2014 Unit 2 exam (CH02_01): ques...

Apr 16, 2020 · Given that Magnesium Hydroxide is an alkali, can we say Magnesium Oxide is an alkali since dissolving Magnesium Oxide in water can produce Magnesium Hydroxide?

Here is a simple minded answer. High melting point compounds tend to follow the octet rule - the number of valence electrons sums to 8. The Group IVB carbides (TiC, ZrC, HfC) have an 8 electron sum (4+4) and have very high melting points - for HfC it is approximately 7100F. The Group IIIB nitrides and phosphides have an 8 electron sum (3+5) and are the highest melting …
