Which would weigh more a brick made of iron or the same size brick made of lead?

Oh, dude, let me break it down for you. So, like, a brick made of lead would weigh more than a brick made of iron because lead is denser than iron. It's all about those atomic weights and stuff, you know? So, if you're looking to impress your friends with some random trivia, there you go!


Will a lead pipe rust?

Lead won't rust in the same way as iron, a white oxide layer will appear overtime, but it won't break away as much as rust on iron.


Is the buoyant force of water on lead greater than that on iron?

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.


Which method would be best to separate a mixture of iron and lead pellets (of the same approximate diameter?

Iron is simply separated with a magnet.


Does sodium hydroxide rust the iron?

No. as rust is caused by the oxidation process of: O2+2H2O+4e = 4OH in sodium hydroxide the hydroxide is already present making it harder to form and therefore making rust harder to form. Sodium hydroxide is a rust inhibitor.


Is a 7 mm mechanical pencil the same as a number 2 pencil?

The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.


Which would weigh more a brick made of iron or the samesize brick made oflead?

A brick made of lead would weigh more than a brick made of iron of the same size. This is because lead is denser than iron, meaning it has more mass packed into a similar volume.

Why do electromagnets make iron magnetic?

The electromagnet causes many randomly oriented magnetic areas in the piece of iron to all align in the same orientation. In some cases adjacent magnetic areas not only align in the same orientation, but they merge into common large areas making it harder for the areas to randomize again.
