What is an independent variable in HCl and Mg?
HCl and Mg are two chemicals. There is no variable involved - independent or otherwise!
What is the equation for HCl Mg?
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.
What is the mass of HCl that would be required to completely react with 5.2 grams of Mg?
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.
What does HCL in clonidine hcl 0.1 mg mean?
Clonidine is a drug that is used to treat attention deficit hyperactivity disorder (ADHD) and hypertension. Clonidine HCl is the hydrochloride salt of Clonidine (the free base), and it is more soluble in water than ins the free base. The 0.1 mg is the usual oral dose.
What volume of 0.500m mgoh is required to neutralize 0.200l of 0.100m hcl?
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)
What is the chemical formula of magnesium metal and hydrochloric acid?
The chemical formula for magnesium metal is Mg, and for hydrochloric acid is HCl.
What is the chemical formula for Mg plus HCl?
Mg + 2HCl = MgCl2 + H2
What is the difference between minocycline 100 mg and minocycline hcl 100 mg?
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...
Balnced equation for Hydrochloric acid and magnesium?
Hydrochloric acid + magnesium ---> Magnesium chloride + hydrogen gasUnbalanced: HCl + Mg ---> MgCl2 + H2Balanced: 2HCl + Mg ---> MgCl2 + H2
Buspirone hcl 15 mg comparison xanax?
Buspirone hcl 14mg comparison to xanax
750 mg of yohimbine extract equals how much yohimbine hcl?
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.
What is the molecular equation for Mg plus HCl?
The molecular equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is: Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2(g)
