What would you see if a piece of magnesium ribbon reacts with dilute hydrocholric acid?
When a piece of magnesium ribbon reacts with dilute hydrochloric acid, you would observe effervescence (bubbling) as hydrogen gas is released. The magnesium ribbon would dissolve in the acid, producing magnesium chloride solution. The solution may also become warm due to the exothermic nature of the reaction.
How do you determine that weights of zinc or copper and what additional information is necessary in to do this?
The weight of zinc or copper can be determined by using a sensitive balance scale. In order to do this, the additional information needed would be the volume or dimensions of the metal piece to calculate its density, then multiply by the weight per unit volume for the specific metal. Alternatively, information on the mass and volume of the metal can also be used to determine its weight.
Why does magnesium go out immedely in nitrogen?
Burning of magnesium (or anything else) requires continuing combination with oxygen. If a burning piece of magnesium is transferred to an atmosphere of nitrogen, no additional magnesium can react with oxygen because none is available for reaction.
Why won't a magnet rust?
No. Rust is a compound of iron, and magnesium is not iron so it cannot rust. Magnesium is however a very reactive metal and it can corrode in the presence of oxygen and water. In fact when you look at a piece of magnesium you are probably really looking at the thin, dull layer of magnesium oxide which coats its surface. If you scrape the oxide off the surface you will see the bright magnesium metal beneath only very briefly because the metal reacts quickly with the oxygen in the air and the oxide re-forms. Many other metals behave in a similar way. You can prevent this reaction from taking place by cleaning the oxide off while the metal is submerged under a relatively unreactive liquid such as oil. Don't use water!
How tp prepare magnesium acetate?
To prepare magnesium acetate, you can react magnesium oxide or magnesium hydroxide with acetic acid. Start by adding magnesium oxide or hydroxide to acetic acid in a controlled manner while stirring until the reaction is complete. Filter the solution to remove any insoluble impurities, and then evaporate the solvent to obtain solid magnesium acetate.
How do you measure the density of a metal?
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
A piece of magnesium weighs 27.5 g and occupies 13.7 Centameter3 what is the density of the piece of metal?
2.01 g/cm3 density equals mass over volume. so 27.3g/13.7cm^3 = 2.01 g/cm^3 Your welcome!!!
What is the density of a piece of metal that has a mass of 277G and a volume of 38cm3?
The density of the metal can be calculated using the formula: Density = Mass / Volume. In this case, Density = 277g / 38cm3 = 7.29 g/cm3.
What is the density of a piece of metal mass of 68g volume of 6cm3?

How much does a piece of metal weigh?
That would vary greatly depending on the type and density of the metal, along with the dimensions of the particular piece. The weight of a piece of anything is the volume times the density.
What is the density of a piece of metal that has a mass of 68g and a volume of 6 cm3?
The density of the metal is 11.33 g/cm3. This is calculated by dividing the mass (68g) by the volume (6 cm3).
What is the density of a piece of metal that has a volume of 10cm3 and a mass of 500g?
Volume = mass/volume = 500g/10cm3 = 50g/cm3
What is the density of a 25g piece of metal that has a volume of 10 cm cubed?
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
What is the density of a 25 gram piece of metal that has a volume of 10 cm cube?
Density= mass/volume 25/10 = 2.5 g/cm3
What is the volume of a piece of metal if the density is 2.3glml and the mass is 1.5g?
Density = Mass/Volume so Volume = Mass/Density. That is, Vol = 1.5 g/2.3 g/ml = 0.652 ml approx.
What lab equipment would you need to measure the density of a piece of metal?
To obtain the density you need to know the mass, and the volume of the object.So you'd have to weigh it using a balance to obtain the mass.The easiest way to measure the volume (particularly if it's an irregular shape) would be via the displacement of water.density = mass / volume
What is the density of a piece of metal that has a mass of 16g and a volume of 2.8 mL?
Density = Mass/Volume = 16/2.8 g/mL = 5.714 grams per mL (approx).
