Why will using so much copper be a problem in the future?
in the future, there may be no copper ores left so other metals will need to be used, however other metals are more reactive than copper, so will eventually dissolve
Are transition metals often found in ores?
Quick and simple answer is that metals are solid and therefore are affected by the gravity of the Earth more than gases. Therefore gases are in the air and solids are on the surface or under the surface of the Earth.
Why are alloys created?
Alloys are more durable than normal metals, this is because its lots of metals together. Its also cheaper to produce than some other metals.
1.4 Gold and Silver often occur in their free states in nature while iron has to be extracted from its ores How is this explainable in terms of the fundamental properties of these metals?
Gold and silver are less reactive than iron
Which metals are not found in ores?
There are a lot more than five. For example, all the alkali and alkaline earth metals are not found naturally in pure form but occur only in compounds. It's actually unusual for a metal to exist in pure form in nature; most of them occur only in compounds.

What is the need of purafication of ores?
Pure metals have more uses than ores, rocks, from the ground. Ores cannot be made into pipes, wires, or sheets of metal for various uses. Unlike the Flintstones, we cannot make a car out of rocks. Purified metals are used to make the frame, the body panels, the electrical wiring etc. for the car.
What physical and chemical properties are used to separate metals from their ores?
Some impurities ,or unwanted substances ,are less dense than water ,so they float in water and can be washed away.Others ,like sulfur ,can be burned away.
Why are there more metals available now than there was 200 years ago?
There are more metals available now than there was 200 years ago. This is because more metals have been harvested.The reason is because of advancements and increased accuracy in technology. Other metals became more readily available overtime as it became possible to extract metals from their ores. These technologies were not available 200 years ago.
If gold is an element and not formed why is it found in greater concentrations in certain places?
Gold like many other elemental metals is found in ores rather than in its pure state and must be refined before ingots of the metal can be produced
What metals softer and more reactive than other metals?
Alkali metals Alkaline earth metals

How are minerals extracted from their ores?
metals are extracted from their ores according to their reactivity series.firstly, metals that are more reactive that carbon are extracted by electrolysis whic is breaking the compounds down using electricity.secondly, metals that are less reactive than carbon are extracted by reduction in which carbon is added to the metal ore, carbon react with oxygen and the metal remain by itself pure.example: Zinc oxide + Carbon ----> Zinc + Carbon dioxideGold and Platinum are found in nature by themselves.
What is the other sources of energy?
Other than what?
What are other sources of CO other than animals?
Other than animals? Gz
