What else can I help you with?
Why do you think that Wegener was unable to prove the theories of continental drift and plate tectonics before his death in 1930?
Wegener was unable to prove the theories of continental drift and plate tectonics before his death because he lacked a mechanism that could explain how continents could move. Additionally, his ideas were met with skepticism and opposition from the scientific community at the time, which hindered further research and experimentation on the topic.
How can you prove you have made hydrogen gas?
You can prove you have made hydrogen gas because you will see bubbles rising from the soloution.You could also get a very tiny amount of the gas and hold a match to it.If it lights the it is most likely to be hydrogen gas +++ The bubbles only prove A gas is being evolved. They do not indicate WHICH gas.
What is the precautionary principle?
The precautionary principle is a guideline for decision making. Some human-induced changes can lead to large or even catastrophic consequences, so those responsible for the change must prove that it causes no harm before proceeding. Objectors do not have to prove that there will be harm. This is a reverse of historical practices where those opposing the change had to prove its harmful effects to prevent the change from going ahead.
How did Alfred Wegener prove that pangaea existed?
Alfred Wegener proposed the theory of Pangaea based on the fit of the continents, similarities in rock formations, and fossil evidence across continents. He also noted similarities in geological structures and climate data that suggested the continents were once connected before drifting apart. However, Wegener's theory was not widely accepted until much later when additional evidence and advancements in plate tectonics supported his ideas.
Why was Alfred Wegener unable to prove his theory about Pangaea?
Alfred Wegener was unable to prove his theory about Pangaea because he lacked a mechanism to explain how continents could move across the Earth's surface. Additionally, Wegener's theory was met with skepticism from the scientific community at the time due to the lack of supporting evidence and alternative explanations being more widely accepted. It wasn't until the development of the theory of plate tectonics in the 1960s that Wegener's ideas were finally validated.
How do you prove metal oxide is basic?
when ash of magnesium is dissolved in water then magnesium hydroxide is formed. MgO + H2O---->Mg{oh}2 hence, the solution is basic in nature.The oxides of metals are basic in nature.Therefore,their aqueous solution turns red litmus blue.
What metal would be the best to make a petrol tanker out of magnesium iron lead copper aluminum tin or zinc?
I just did an experiment on it and the obvious choice was copper. This was simply because of the "Reactivity Series" which lists metals from most reactive to least reactive. Furthermore copper was used for the original cars many years ago, however alloys such as steal prove to be tougher as well as cheaper which is mainly the reason why it is prefered.-glad i could help-
How do you prove the object is magnetise?
hold a piece of iron or magnesium up to it and if it attracts it is magnetic
How can you prove that gold is a metal and plastic is a non metal as both of them are unreactive?
Metals are conductive.
How could you prove that carbon dioxide is produced when a metal carbonate is heated?
carbon dioxide is produced when a metal carbonate is meated which lets out all the flames of the cell's into the posturational motivation calastural system which means that it is not proven.
Product of Hydrochloric acid and Magnesium oxide?
Magnesium chloride and water are produced in the stated reaction.
To pass a literacy test a prospective voter had to prove he could?
The prospective voter had to prove he could read and write.
How could you prove that carbon dioxide is produced when metal carbonate is heated?
wag 1 g (don't think any one does know the answer to this question apart from mr. mcnally) :o
How can you prove that an object is a magnet?
See whether that object can attract nickel,steel,and metal.
What was the single fact that montag could not prove?
The single fact that montag could not prove was that Clarisse has been there but he had no evidence. Montag saw a fire through the trees.
How do you prove that given salt is carbonate of a metal?
To prove that a salt is a carbonate of a metal, you can add an acid to the salt. If carbon dioxide gas is produced, it indicates the presence of a carbonate. This can be further confirmed by testing the gas with limewater; if it turns milky, it confirms the presence of carbon dioxide, which suggests the salt is a carbonate of a metal.
How could a citizen prove his citizenship?
yes
