Because iron is higher on the reactivity series meaning it can displace the copper
The nitrogen bubbles will displace the air and the N2 bond will not break up so it will not effect the conductivity of the water.
copper
No. The more reactive metals do displace hydrogen. Bases are substances that when adde to water increase the concentration of OH-
My guess is, that any available water can act as a nucleophile and displace the halide producing the alcohol.
The Joke: Not much it sank The truth: A floating boat will displace the same weight in water that it weighs. So the real question is how much does it displace or how much does it weigh
7.48 gals water
Quick and dirty answer: Because they are built to be essentially hollow, they are much larger in volume than the water they displace, and so in effect they are much less dense over all than the water they displace.
An amount that weighs as much as the ship does.
Air is displace by water because water is much denser than air and therefor is much harder to compress.
the weight of the ship is equal to the amount of water displaced
It must displace as much weight in water as it weighs (roughly 600 cubic meters of water). These boats have huge hulls, so can easily displace this much without beginning to sink.
The Titanic displaced 52310 tons.
No
buoyancyAn object that displaces its own weight in water is said to be "floating".
20,000 cubic kilometres
You must displace as much water at the metal weighs. So there is equillibrium between the metal and the water.
