What else can I help you with?
What would happen if a piece of brass were immersed in 6 M HCL Would you expect the zinc in the brass to react leaving the copper behind?
When brass, which is an alloy primarily consisting of copper and zinc, is immersed in 6 M hydrochloric acid (HCl), the zinc will react with the acid, leading to the formation of zinc chloride and hydrogen gas. The copper in brass is relatively unreactive in comparison, so it would largely remain unaffected during this process. As a result, you would expect the zinc to dissolve, leaving behind the copper.
How do you prepare 0.05M calcium chloride?
To prepare a 0.05 M calcium chloride (CaCl₂) solution, first calculate the required mass of CaCl₂ by using its molar mass, which is approximately 110.98 g/mol. For 1 liter of a 0.05 M solution, dissolve 5.55 grams of anhydrous CaCl₂ in distilled water. Add the calcium chloride to a volumetric flask, then fill the flask with distilled water up to the 1-liter mark. Mix thoroughly to ensure the solute is fully dissolved.
How do you prepare 100mM of magnesium chloride?
To prepare a 100mM magnesium chloride solution, you would need to first calculate the molecular weight of magnesium chloride (95.21 g/mol for MgCl2). Then, weigh out the appropriate amount of magnesium chloride hexahydrate (MgCl2·6H2O) or anhydrous magnesium chloride to dissolve in a specific volume of water to achieve a final concentration of 100mM. Finally, ensure the solution is thoroughly mixed before use.
How would you prepare a 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water?
You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride.
What is 0.6 M of NaCl?
0,6 M of sodium chloride is 35,064 g.
What mass of sodium chloride will be required to prepare 100 cm3 of 0.0282 M of sodium chloride?
The answer is 0,1648 g NaCl.
What is the density of 1 M solution of zinc chloride?
Density is about 1.1 g/mL. We just made a batch of this in my lab.
What part of a kilometer is 5 m?
.005
.005 m equals how many cm?
0.5 CM
How many grams of sodium chloride are required to prepare 500.0 mL of a 100 M solution?
In this instance, 50 mol of sodium chloride is needed and molar mass of NaCl is 58.5 g/mol. Hence the mass we need is 29250 g. But this amount of salt could not be dissolved in 500 ml of water, so we cannot prepare this solution practically.
How do you prepare a 0.5 M hydroxylammonium chloride NH2OH-HCl solution?
To prepare a 0.5 M hydroxylammonium chloride solution, you would dissolve the appropriate amount of NH2OH-HCl in a specific volume of water. Calculate the moles of NH2OH-HCl needed (Molarity x Volume) and dissolve it in water to make the desired volume. Always remember to handle the compound with care due to its toxicity and reactivity.
How do you make a standard 0.1 M Barium Chloride?
To prepare a 0.1 M solution of Barium Chloride, you would need to dissolve 3.526 grams of BaCl2·2H2O in distilled water and then dilute to a final volume of 1 liter. Make sure to accurately weigh the BaCl2·2H2O and use a volumetric flask to achieve the desired concentration.
How do you prepare 100mM of magnesium chloride?
To prepare a 100mM magnesium chloride solution, you would need to first calculate the molecular weight of magnesium chloride (95.21 g/mol for MgCl2). Then, weigh out the appropriate amount of magnesium chloride hexahydrate (MgCl2·6H2O) or anhydrous magnesium chloride to dissolve in a specific volume of water to achieve a final concentration of 100mM. Finally, ensure the solution is thoroughly mixed before use.
How to prepare 1 molar zinc uranyl acetate solution?
Theoretically: dissolve 571,59 g of zinc uranyl acetate in 1 L water. But zinc uranyl acetate is not so soluble. I recommend a concentration of max. o,1 M (57,159 g of zinc uranyl acetate in 1 L water).
What is the anwer of the one half equal centimeter?
The conversion according to the question . 1 m=100 cm . But, 1 cm=0.01 m. 1/2 cm =0,.005 m.
How many m are in 5 mm?
"milli-" means "thousandths of a unit". Then, 5 meters is 5,000 millimeters.
How would you prepare a 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water?
You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride.
