Yes, magnesium is relatively expensive.
The reasons being because magnesium is a very large commercial market commodity compared to the abundance of magnesium ore in certain geographic countries/locations.
Magnesium is also very difficult to mine, because it is very reactive and therefore harder to separate from its other compounds, which is reflected in the price of the metal.
Nylon is not an expensive material.
Magnesium is used in some engines due to its lightweight properties, which can help improve fuel efficiency and reduce overall vehicle weight. However, magnesium is highly flammable and can ignite at lower temperatures, making it a safety concern in some engine applications. Additionally, magnesium is more expensive than other materials like aluminum or steel, which may limit its use in engines.
The long answer would factor in the commercial market for metals as commodities and the relative abundance of magnesium ore and iron ore in certain geographic areas. The short answer, and the one more relevant to chemistry, is that magnesium is higher on the reactivity series than iron, and thus is slightly harder to separate from its compounds.
Mg stands for Magnesium. It is placed in group-2.
Magnesium oxide is formed when magnesium metal reacts with oxygen. It is an oxide of magnesium. Magnesium is the metal, and magnesium oxide is the resulting compound formed when magnesium reacts with oxygen.
i am doing homework and this is what i put: steel is extacted using a blast furnace which is quick and relatively cheap. however to extract titanium, magnesium is needed because it is more reactive. magnesium is extracted by electrolysis, which is expensive therefore it is not cheap to buy. you have to buy the magnesium to extract the titanium, which is why titanium is expensive hope this helped and you can copy it word for word i dont care :)
is oil cheap or expensive

It isn't "cheap" but it isn't as expensive as oak.
The answer here would depend on what you consider to be cheap and or expensive and for that matter what products you wish to buy ...
