Why is the frame on a bike made out of alloy and not pure aluminium?
Aluminium alloys are stronger than pure aluminium, which is comparatively soft. Pure aluminium is also considered chemically reactive (thus the layer of aluminium oxide which coats the metal due to oxidation). Pure aluminium hardly exists due to its strong affinity with oxygen in air. In fact, aluminium foils and beverage cans are also alloys of aluminium, with about 92 to 99% of aluminium. So likewise, bike frames are also made of alhminium alloys because of its characteristics of being strong and lightweight.
Why aluminium is not extracted from alumina by pyrometallurgical operations?
Aluminium is not extracted from alumina by pyrometallurgical operations because the melting point of alumina is very high (over 2000°C), making it energetically intensive and expensive to extract aluminium through traditional pyrometallurgical methods. Instead, aluminium is typically extracted from alumina using the Hall-Héroult process, which involves electrolysis at a much lower temperature.
What combination of metals would electrolytic corrosion be most pronounced.?
if this is for a course with T4TS which i think it is as i searched the same question, its D aluminium and magnesium
What does algae provide creatures?
Algae provides essential nutrients like oxygen and food to various creatures in aquatic ecosystems. It forms the base of the food chain, being a source of energy for many marine organisms such as small fish, shrimp, and other aquatic animals. Algae also plays a crucial role in maintaining oxygen levels in water bodies, supporting the overall health of ecosystems.
What are the characteristicts of Aluminium involved in fire?
Aluminium has a high melting point of 660°C, so it does not catch fire easily. However, when it does burn, it produces a bright white flame and a white powdery ash of aluminium oxide. Aluminium's high thermal conductivity also helps dissipate heat quickly, reducing the risk of spreading fire.
What skills does posiedon have?
He is the god of the sea, so anything having to do with water or aquatic sea creatures.
What elements in in aluminium?
Aluminium is actually an element, so the only element in aluminium is aluminium.
What fish if any are toxic to freshwater aquatic turtles?
You have things the wrong way round. Aquatic turtles make the water toxic to fish. Fish have to try to breath by passing the foul water over their gills. Turtles breath air so the poisons (Ammonia and Nitrite) in the water will not do them any damage.
A vertebrate that lives in water and has fins?
You have the amphibians which are born in the water and grow into air breathing creatures, (such as the frog). Then there are the aquatic vertebrates which are wholly, or chiefly, water living creatures.
Do dolphins give birth in the ocean or upon land?
Dolphins are aquatic creatures, they don't go on land at all; so they woulds have no opportunity to give birth on land.
Is aluminium a living thing?
Aluminium is a metal, so is non-living.
Is heptane hazardous to the environment?
Yes, heptane is considered hazardous to the environment. It is a volatile organic compound that can contribute to air pollution and ground-level ozone formation. It can also be toxic to aquatic organisms if released into water bodies.
How easily does aluminium erode?
Aluminium is not a hard metal so the erosion is very possible.
What are substances which are rich in aluminium?
Aluminium is the third most abundant element on earth, it is highly reactive so is very rarely found as pure aluminium. It is found in concentrated levels in bauxite, which is mined and then refined into aluminium
Are the oceans dying?
Millions of tons co2 are dissolved into the ocean and that changes the water so that hard shelled creatures lose their shells and die. Also there are growing dead spots where the water loses the oxygen and becomes toxic with hydrogen sulfide that kills deep dwelling creatures.
How many protons does an aluminum atom contain?
The atomic number of aluminium is 13. So there are 13 protons in aluminium.
Are red-eared slider turtles aquatic?
They are semi-aquatic, so yes
