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.
Does hexaaminecobalt III chloride react with concentrated HCl?
No, hexaaminecobalt(III) chloride does not react with concentrated hydrochloric acid (HCl) due to the stability of the complex and the lack of available sites for the acid to attack. The hexaaminecobalt(III) complex is inert and does not readily undergo substitution reactions with halide ions.
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.
Why no gas is released when sulphur is added to dilute hcl?
When sulfur is added to dilute hydrochloric acid (HCl), no gas is typically released because sulfur is a non-reactive element and does not readily react with HCl to produce a gas. Sulfur can only react with strong oxidizing agents, such as concentrated nitric acid or hot concentrated sulfuric acid, to release sulfur dioxide gas.
What volume of 5.0 molar hydrochloric acid is needed to react with 3.00g of magnesium metal?
To determine the volume of 5.0 M HCl needed to react with 3.00g of magnesium metal, first calculate the moles of magnesium using its molar mass. Then, use the balanced chemical equation (2HCl + Mg -> MgCl2 + H2) to find the moles of HCl needed. Finally, use the molarity formula (M = moles/volume) to find the volume of HCl needed.

What reacts quickly dilute HCI or concentrated HCI?
Concentrated hydrochloric acid (HCl) will react more quickly than dilute HCl because it has a higher concentration of hydrogen ions, which increases the likelihood of collisions and reactive interactions with other substances.

Is adding HCl to Mg and physical or chemical change?
Adding HCl to Mg will result in a chemical change. The HCl will react with the Mg to form magnesium chloride and hydrogen gas. This demonstrates a chemical reaction where new substances are formed.
How do you prepare 0.2 mol per liter HCl from concentrated HCL?
To prepare 0.2 mol/L HCl from concentrated HCl (e.g., 37% HCl), you would need to dilute the concentrated HCl with water in the appropriate ratio. Since the concentrated HCl usually has a density of around 1.19 g/mL, you can use the formula M1V1 = M2V2 to calculate the volume of concentrated HCl needed. After calculating the volume of concentrated HCl required, add water to make up the final volume of 1 liter to achieve a 0.2 mol/L HCl solution.
Why HCl react with NaCl?
NaCl and HCl doesn't react.
How do you make 4N HCl from concentrated HCl?
To make 4N HCl from concentrated HCl, you can dilute the concentrated HCl with water in a ratio that will give you a final concentration of 4N. For example, to make 1L of 4N HCl, you would mix 273 ml of concentrated HCl (37% w/w) with 727 ml of water. Always remember to add acid to water, not the other way around, and wear appropriate safety gear when working with concentrated acids.
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.
What is the molariy of concentrated HCl?
Concentrated HCl is typically 36.5% industrially. It is thus almost exactly 10 Molar.
