Does mg react with znso4?
No, magnesium (Mg) does not react with zinc sulfate (ZnSO4) under normal conditions. Magnesium is higher in the reactivity series than zinc, so it does not displace zinc from its sulfate compound.
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.
Mg ribbon is allowed to react with hcl and another with ch3cooh in which fizzing will occur more vigorously and why?
Mg ribbon will react more vigorously with HCl compared to CH3COOH because HCl is a stronger acid than CH3COOH. This higher acidity of HCl results in a faster reaction rate with magnesium, leading to more intense fizzing.
What volume of 5.0 molar hydrochloric acid is needed to react with 3.00g of magnesium metal?
100 mL 5.0 M HCl solution (0.50 mol HCl) is sufficient to fully react with 3.00g Mg, which is 3 (g) / 12 (g/mol) = 0.25 mol Mg because it needs a molar '1 to 2' ratio with HCl:(1) Mg + 2 HCl --> Mg2+ + H2 + 2 Cl-
Is adding HCl to Mg and physical or chemical change?
Adding Hydrochloric acid to magnesium induces a chemical change, according to the reaction: Mg(s) + 2HCl(aq) > MgCl2(aq) + H2(g)
Does mg react with znso4?
No, magnesium (Mg) does not react with zinc sulfate (ZnSO4) under normal conditions. Magnesium is higher in the reactivity series than zinc, so it does not displace zinc from its sulfate compound.
Will magnesium sulfate react with zinc?
No, Zn is less reactive than Mg

Does HCL react on burned Mg?
Yes, when hydrochloric acid (HCl) is added to burned magnesium (Mg), a chemical reaction will occur to form magnesium chloride (MgCl2) and hydrogen gas (H2). This is an example of a neutralization reaction between an acid and a base.
How could the reactivity of magnesium be compared to zinc?
Magnesium is more reactive than zinc, Mg will react with cold water though very slowly - it will react rapidley with hot water - zinc will not react at all, thats 1 way, another way would be to make up 2 solutions, 1 of Zn(NO3)2 and the other of Mg(NO3)2 then dangle a wire of Zn in the magnesium nitrate and a wire of Mg in the zinc nitrate. Nothing will happen in the Zn in Mg(NO3)2, but in the other a radox reaction will take place... Mg(s) + Zn(NO3)2(aq) --> Zn(s) + Mg(NO3)2(aq) The Mg is oxidised from 0 to +2 and the Zn is reduced from +2 to 0. The zinc will precipitate out as sharp crystals. This reaction will take a long time so you need to set up a camera and leave the reaction for a few hours. * Technically some of the Mg will react with the water in a separate reaction... Mg(s) + 2H2O(l) --> H2(g) + Mg(OH)2(s)
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 effect of HCl on burned Mg strip?
When HCl is added to a burned Mg strip, it will react with the magnesium oxide formed during the burning process, producing magnesium chloride and water. The reaction will produce fizzing or bubbling due to the release of hydrogen gas. Overall, the HCl will dissolve the magnesium oxide and form a solution of magnesium chloride.
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.
Magnesium zinc nitrate yield what?
Magnesium metal and Zinc Nitrate react according to the equation: Mg(s) + Zn(NO3)2(aq) --> Mg(NO3)2(aq) + Zn(s) written ionically as: Mg(s) + Zn2+(aq) --> Mg2+(aq) + Zn(s) This is a typical metal displacement reaction
