well obviously, if:
Hydrochloric acid + Magnesium -> Magnesium Chloride + Hydrogen
I'd say you CAN separate the magnesium Chloride by using Electrolysis ( using direct current to separate a compound to decompose into elements), but the Hydrogen doesn't have to, because there is an element not a compound.
If you are talking about how you can separate HCL and Mg by itself, then obviously you can't because it is already separated.
The reaction between hydrochloric acid (HCl) and magnesium (Mg) produces magnesium chloride (MgCl2) and hydrogen gas (H2). The balanced chemical equation is 2HCl + Mg -> MgCl2 + H2.
The balanced chemical equation for the reaction between HCl and Mg is: Mg + 2HCl -> MgCl2 + H2. One mole of Mg reacts with 2 moles of HCl. Calculate the moles of Mg in 5.2 grams using the molar mass of Mg. Then use the mole ratio to find the moles of HCl needed, and finally calculate the mass of HCl using its molar mass.
The chemical formula for magnesium metal is Mg, and for hydrochloric acid is HCl.
my pharmacist says they are the same thing.. i just called him b/c i was prescribed the HCL this time and I was wondering why...
Yohimbine HCl is typically 2.4 times stronger than yohimbine extract. Therefore, 750 mg of yohimbine extract would be roughly equivalent to around 312.5 mg of yohimbine HCl.
HCl and Mg are two chemicals. There is no variable involved - independent or otherwise!
No, oxycodone HCl 5 mg does not contain acetaminophen. Oxycodone is a standalone opioid pain medication, while acetaminophen is a separate drug often combined with opioids like oxycodone in medications such as Percocet or Endocet.

Im assuming you mean Mg(OH)2 and not MgOHThe reaction between Mg(OH)2 and HCl is as follows: Mg(OH)2 (aq) + 2HCl (aq) -> MgCl2 (aq) + 2H2O (l)First the number of mole is found: n(HCl) = c × v = 0.100M × 0.200L = 0.0200mol (to 3 significant figures)Next we find the number of mole of Mg(OH)2:n(Mg(OH)2) ÷ n(HCl) = Coefficient of Mg(OH)2 ÷ Coefficient of HCl n(Mg(OH)2) ÷ n(HCl) = 1 ÷ 2 therefore:n(Mg(OH)2) = (1 ÷ 2) × n(HCl) n(Mg(OH)2) = (1 ÷ 2) × 0.0200moln(Mg(OH)2) = 0.0100mol (to 3 significant figures)Finally we calculate the volume of Mg(OH)2 reacted:v(Mg(OH)2) = n ÷ cv(Mg(OH)2) = 0.0100mol ÷ 0.500MThereforev(Mg(OH)2) = 0.0200L (to 3 significant figures) = 20.0ml (to 3 significant figures)
The molecular equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is: Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2(g)
