Iron has a greater density.
Greater in what way? They both have the same mass. Aluminium, being less dense will have a greater volume, but being more abundant will have a smaller value.
Both are equal Depends if they weigh 1 kilogram where they are or one kilogram compared to Earth's gravitational pull. ~The kilogram technically does not measure weight, it measures mass. If all the items you mention have the same mass then the densest material (iron) has the greatest weight because it displaces the least volume of air. A balloon filled with one kilogram (around 5600 liters) of helium will float in the air. If you want to measure weight, the proper unit is the Newton.
Iron would require a higher amount of heat due to the fact that it is a metal and has stronger bonds than water does. Water is made up of hydrogen bonds which allow it to heat up quickly.
Since kilograms are the unit we use to measure mass, the answer is no: both have 1kg. of mass. :D
Iron has a greater density.
1 kg of lead has more volume And that's because lead is more dense than copper. A given volume of lead weighs more than that same volume of copper. It turns out that 1kg of something will weigh the same as 1kg of something else, though the two may have different volumes for that weight.
Not sure if this is a serious question but...A kilogram is a unit of mass, or in this case, weight.A kilogram is a kilogram.One kilogram of anything is a kilogram.1 kg of iron = 1 kg of wool.
When compared by volume, copper is best, then aluminum and finally iron. When compared by weight, aluminum is better than copper. You have to compare by volume because aluminum is so much lighter than copper, an aluminum wire that weighed the same as a copper wire would be much bigger and harder to work with.
The answer is yes because one is twice the weight of the other and is made of exactly the same material. The answer would be "No" if the materials differed.
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
The iron is higher in they reactivity scale than copper , Therefore the copper will be replaced by iron to make iron sulfate and copper by itself.
true
No, copper is less reactive than iron.
Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.
That depends on the amounts, of course - what exactly you are comparing. The buoyant force depends on the volume. For a certain volume of lead, there will be the same buoyant force as for the same volume of iron. On the other hand, since lead has a greater density, the buoyant force on a certain amount of MASS of lead will be less, compared to iron, since the same mass of lead will use up less volume.
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
