What else can I help you with?
What elements does not form bonds easily because it has a full outer shell aluminum carbon helium calcium?
Helium
Why is carbon not used for reducing aluminum from aluminum oxide?
Carbon cannot be used for reducing aluminum from aluminum oxide because aluminum is more reactive than carbon. This means that aluminum is not easily displaced by carbon in the reduction reaction. Instead, aluminum is typically extracted from its ore using electrolysis.
Explain why calcium hydroxide can be used in this way?
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
What is better to hunt with carbon or aluminum arrows?
Carbon arrows are superior for hunting. Aluminum arrows are less expensive, lighter (faster), and if they get bent can be straitened easily. Carbon arrows are a little pricier, but are stronger and penetrate the game better because they can be a little skinnier.
Why can't aluminium be extracted from aluminium ore using a blast furnace?
Because it is more reactive then carbon to be extracted in a blast furnace. Remember carbon is the reducing agent and for it to work the metal being extracted has to be lower in the reactivity series, e.g. iron
Why is calcium used as a reducing agent?
Because calcium oxidizes relatively easily.
Calcium does not form bonds easily because it has a full outer shell?
False - calcium forms ionic bonds very easily because it has only 2 electrons in its outer shell
Which elements does not form bonds easily because it has a full outer shell?
aluminum
Carbon is important to life because carbon compounds break down easily and liberate?
Energy. :)
How many outer and inner shells does aluminum have?
No it doesn't... Aluminum has 3 extra electrons in the outer shell
Why is pineal sand important to radiologists?
it is calcium concretions. It is easily seen from a radiograph and radiologists use it as a landmark because it is easily identified.
What is more easily oxidized led or calcium?
Calcium.
