To balance the chemical equation representing this reaction, first write the unbalanced equation: HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + H2O(l). To balance it, you would need to ensure the same number of each type of atom on both sides of the equation. In this case, you would need to put a coefficient of 2 in front of HCl(aq) and MgCl2(aq) to balance the equation: 2HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2H2O(l).
Why is milk of magnesia used to treat digestion?
Who would have thought that the thick, white, chalky, foul mixture called Milk of Magnesia (MoM), normally used as a laxative, could be used for other health issues. Yes, according to Joe and Terry Graedon's The People's Pharmacy, Milk of Magnesia may help with the following:
1. ACNE: Rub it on face, at bedtime. One reader wrote how it helped their son's cystic nodular acne. The Graedons had no explanation as to why it helped.
2. SEBORRHEIC DERMATITIS: Rub on skin. According to the Graedons this has been known to help.
3. ANTIPERSPIRANT/DEODORANT: Spread on underarms with fingers. Some people swear by this. And, it's safe to use because it contains no aluminum. And no stains.
I have no idea if any of these home remedies actually work, but it's probably worth a try. If MoM is made to ingest, there certainly shouldn't be a problem applying it to the skin.
However, I remember being told, as a teen, that Mercurochrome was good for skin problems. So, I liberally applied it to my face one evening. I was scheduled to take the SATs the following day. When I woke up the next morning and went to wash it off, I found that nothing could remove the red splotches plastered all over my face. They failed to specify it had to be the whiteMercurochrome.
Considering Milk of Magnesia is white, you should have no problems.
UPDATE 10/08: I decided to give it a try as a deoderant, and it does work!
Best advice... UAD (use as directed).
What reaction happens when you mix carbon and magnesium?
you get gravity because your holding them together tightly
NO. North-North Repel South-South Repel North-South Attract South-North Attract
How is magnesium carbonate obtained?
Magnesium can be extracted from the minerals Dolomite (CaCO3·MgCO3) and Carnallite (KCl·MgCl2·6H2O), but is most often obtained from seawater
Example: The gas is tested with a glowing splinter for oxygen.It's meaning should be a splint which grows stronger in the presence of sunlight. If you think the answer is a splint in your thumb, you are wrong.meaning:splint in the thumb (wrong)
How many free electrons are there in magnesium?
Always 2. With every atom except for Hydrogen there are only 2 electrons in the subshell 1s.
The rest goes
2s2, 2p6, 3s2, 3p2
2+2+6+2+2 = 12 (Hence atomic number 12)
or
2, 8, 2
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
