Magnesium reacts with steam faster than cold water because magnesium needs to burn to get magnesium oxide and to get magnesium oxide there has to be heat and since steam is already heated it doesn't need much time, but the cold water needs time to heat first to react.
What is the diagram particle to show the arrangement of atoms in a solid magnesium oxide.?
[well you would show the 2 diffrent particle (oxygen and magnesium) with 1 magnesium particle and 2 oxygen ones attached to it . this is known as MgO2]
i believe it is MgO as the electron number is too big to support 2 molecules of oxygen
If 13.0g of MgSO47H2O is thoroughly heated what mass of anhydrous magnesium sulfate will remain?
8.79 grams of magnesium sulfate will remain.
What is the role of magnesium?
Magnesium is an essential element in biological systems. Magnesium occurs typically as the Mg2+ ion. It is an essential mineral nutrient (i.e., element) for life and is present in every cell type in every organism. For example, ATP (adenosine triphosphate), the main source of energy in cells, must be bound to a magnesium ion in order to be biologically active. What is called ATP is often actually Mg-ATP. As such, magnesium plays a role in the stability of all polyphosphate compounds in the cells, including those associated with the synthesis of DNAand RNA.
Over 300 enzymes require the presence of magnesium ions for their catalytic action, including all enzymes utilizing or synthesizing ATP, or those that use other nucleotides to synthesize DNA and RNA.
In plants, magnesium is necessary for synthesis of chlorophyll and photosynthesis.
Are magnesium and calcium alkaline?
Magnesium isn't considered an alkali metal, it is an alkali EARTH metal. That fact is true because of the two valence electrons that the element magnesium contains in its outer energy level

MgCl2 plus 2H20 produces Mg(OH)2 plus 2HCl
What is the correct formula for for magnesium phosphate?
The chemical formula for magnesium phosphate is Mg3(PO4)2. This mineral is very important and keeps the human body working properly.
Is milk of magnesia a heterogeneous mixture?
Yes, milk of magnesia is a heterogeneous mixture. It contains insoluble solid particles of magnesium hydroxide suspended in a liquid, resulting in a mixture with visibly different components that do not fully dissolve.
What is the charge of the magnesium in magnesium oxide?
The molar mass of Magnesium Oxide (MgO) is 40.3044 grams per mole. This means in chemistry terms that there is 1 gram per 6.02 x 1023 molecules of Magnesium Oxide (the ratio for grams to molecules would be 1:6.02 x 1023)
What is the state symbol for magnesium sulfate?
It is in solid state.It is a metal.
Answer:
Pure magnesium is not found in nature as it is reactive with many substances. Commercial sources (ores and minerals) include carnallite, dolomite, brucite, magnesite, ovaline and talc.
Magnesium also also exists as a soluble chloride salt in seawater, solution mined salt and other (NaCl) salt sources.
Why magnesium is used in grignard reagent?
The point of a Grignard reaction is to form a new carbon-carbon bond. To do this, you need a reagent with a relatively negative carbon. This is unusual, since carbon has a fairly low electronegativity - 2.5 - and thus generally has a partial positive charge, rather than a negative one. However, magnesium has an even lower electronegativity, namely, 1.2. The large difference in electronegativity between carbon and magnesium, 1.3, creates a very polar covalent bond between the two when they are bonded to each other. Thus, magnesium is necessary in the Grignard reagent because it creates the partial negative charge on the carbon to which it is bound, allowing the reaction to happen.
When magnesium (Mg2 ) and fluorine (F1-) combine in an ionic bond the resulting formula will be?
Mg2F
What is the standard cell notation of a galvanic cell made aluminum and magnesium?
Mg(s) | Mg2+(aq) Al3+(aq) | Al(s) and that is how a pro does it
Where do you find a magnesium?
There are over 60 minerals in which magnesium is found. Brucite, carnallite, dolomite, magnesite, olivine and talc are the important commercial ones. Note that magnesium can also be produced from magnesium-containing compounds recovered from brines, sea water and from wells. Links are provided to the relevant Wikipedia articles.
What gives magnesium and oxygen?
Magnesium = Mg+2
Oxygen = O-2
(Mg+2)+(O-2) = MgO = Magnesium Oxide
so the formula for oxygen + magnesium - oxygen + magnesium oxide
How do you separate magnesium from seawater?
First, the sea water is collected in large basins and heated to evaporate some of the water. This yields a concentrated solution of water and various salts which are mixed with calcium hydroxide (lime) to yield a magnesium hydroxide precipitate. The precipitate is then reacted with hydrochloric acid to yield magnesium chloride. This is then separated into molten magnesium metal and chlorine gas ions through the electrolysis process. The chlorine is reacted with hydrogen to yield hydrochloric acid to be recycled, while the molten magnesium is then cast into ingots.
