2Mg(s) + O2(g) -> MgO(s)
2Mg + O2 → 2MgO
That would be Magnesium Oxide (since a single element cannot decompose) which decomposes into Magnesium and Oxygen. Magnesium Oxide --> Magnesium + Oxygen or the balanced chem. equation: 2MgO --> 2Mg + 02
4Al(s) +302(g) ----> 2Al2O3(s)
2Mg + O2 ---> 2MgO
The complete combustion of ethanol in oxygen proceeds according to the balanced equation C2H6O + 3 O2 -> 2 CO2 + 3 H2O.
WORD EQUATION: Magnesium + Oxygen --> Magnesium oxide SYMBOLS: 2Mg + O2 --> 2MgO
2Mg + O2 → 2MgO
2Mg + 0 2 = 2MgO
That would be Magnesium Oxide (since a single element cannot decompose) which decomposes into Magnesium and Oxygen. Magnesium Oxide --> Magnesium + Oxygen or the balanced chem. equation: 2MgO --> 2Mg + 02
The word equation is magnesium + oxygen(air) = magnesium oxide. The Balanced chemical eq'n is 2Mg(s) + O2(g) = 2MgO(s)
You would start with writing the equation out, ensuring the compounds are balanced and neutral: MgO + H2O -----> Mg(OH)2 In this case, the equation is already balanced - there are two hydrogen, one magnesium, and two oxygen atoms on each side.
magnesium+oxygen = magnesium oxide
magnesium oxide
I'm not entirely sure but an unbalanced equation is: Mg + O2 -----> MgO
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.
2Ca+O2---->2CaO
This is an example of displacement of hydrogen in water by a metal. Active metals react with water/steam to produce metal hydroxides and hydrogen. The balanced chemical equation is: Mg(s) +2H2O(g) yields Mg(OH)2(aq) + H2(g)
