What else can I help you with?
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
Why doesnt zinc react with magnesium nitrate or iron chloride?
Zinc does not react with magnesium nitrate or iron chloride because zinc is less reactive than magnesium and iron. In a chemical reaction, a more reactive metal will displace a less reactive metal from its compound. Since zinc is lower in the reactivity series compared to magnesium and iron, it will not displace them from their salts.
What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
Is iron less dense than silver?
Silver is more dense because silver is around 10.5g/cc, an iron around 7g/cc. silver atomic number 47, where as iron is 26. This means the nucleus will be much heavier, but also take up more space.
What does more iron and magnesium make magma?
More iron and magnesium in magma can make it more dense and viscous. This can result in a thicker magma that is less likely to flow easily. It may also affect the melting temperature and can influence the type of volcanic eruptions that occur.
What is less dense water basalt iron or granite?
Water is less dense than any of the other materials listed.In order of density from least to highest:Water (least dense)GraniteBasaltIron (most dense)
Would magnesium and iron nitrate react?
No, as magnesium is more reactive, and would 'keep' the nitrate.

Does magnesium react with iron chloride?
yes! it does because magnesium is higher in reactivity series than iron , so the magnesium atom would displace or push out the iron atom from the compound and join with chloride, leaving the pure iron out of the compound Mg + FeCl2 -- MgCl2 + Fe

Is iron less dense than water?
No, else it would float
Why is calcium fluoride have a smaller boiling point then magnesium fluoride?
The calcium ion is larger than the magnesium ion and so the charge on it is less dense. This makes it less attracted to the fluoride ions
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?
These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.
Do iron and magnesium oxide react chemically?
Iron and magnesium oxide can react chemically to form iron(II) oxide and magnesium metal. The reaction occurs when iron is heated with magnesium oxide in a high temperature environment, leading to the transfer of oxygen from magnesium oxide to iron.
