What igneous rock or magma has the lowest silica content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.Read more: Which_igneous_rock_out_of_granite_basalt_andesite_and_peridotite_has_the_lowest_silica_SiO2_content
Why doesnt zinc react with magnesium nitrate or iron chloride?
Magnesium and iron are both more electromotive then zinc, so zinc can't displace them in a compound.
How do the igneous rocks granite and diorite form?
They form in essentially the same way, the only real difference being in composition. They form as magma slowly cools deep underground, allowing large crystals to form. Granite forms from magma that is rich in silica, sodium, and potassium. Diorite forms from magma that has somewhat less silica and more iron, calcium, and magnesium.
Why rhyolitic and andesitic magmas associated with more explosive eruptions?
Andesitic magma is more viscous and generally has more gas trapped in it. It is this the expansion of this gas under reduced pressure that drives the explosive force of an eruption. More gas means a more violent explosion.
Why is the magnesium the most reactive metal among silver copper lead zinc and iron?
magnesium is an alkaline earth metal. silver, copper, lead, zinc, and iron are transition metals. alkaline earths are naturally more reactive then transition metals.
Is it much more expensive to make magnesium then iron?
yes
Would magnesium and iron nitrate react?
No, as magnesium is more reactive, and would 'keep' the nitrate.
Where did gabbro come from?
Gabbro forms from a magma that is rich in iron and magnesium, and poor in silica (quartz). The magma cools and crystallizes deep below the earth's surface. Gabbro is from the same kind of magma as basalt and diabase, but because it cools more slowly, it develops larger crystals.
What element is most reactive sodium magnesium or iron?
Sodium is more reactive than either magnesium or iron.
Is iron more reactive than magnesium?
In a short answer No. But I can't really explain why.

What is the reaction of iron and magnesium sulphate?
Fe + MgSO4 --> FeSO4 + Mg Fe(iron)is more reactive than mg( magnesium) ........ therefore iron will displace magnesium....... hence it is a displacement reaction.............
Why silica rich magma is more dangerous than iron rich magma?
The silica-rich magma, also called felsic magma, is more viscous than iron-rich or mafic magma. This means resists flow more (just as syrup is more viscous than water). The high viscosity means that the felsic magma can trap more gasses, leading to explosive eruptions, rather than effusive ones.
Why doesnt zinc react with magnesium nitrate or iron chloride?
Magnesium and iron are both more electromotive then zinc, so zinc can't displace them in a compound.
What is Word equations of reaction of magnesium and iron with hydrochloric acid?
Magnesium(s) + Iron(s) + HCl(aq) -> MagnesiumChloride(aq) + Hydrogen(g) + Iron(s)Iron will not react with hydrochloric acid as magnesium is more reactive than iron , so magnesium will react with hydrochloric acid to give salt and hydrogen gas while iron is deposited.METAL + ACID -> METAL SALT + HYDROGEN GAS

What is more active iron or silver?
Iron is several times more active than silver.
