What melts faster?
Metals with high or low density? I think I've heard that aluminum melts at lower temperatures than steel, for example.
Hello, I solved this problem like this, but I'm unsure about my solution. Can someone please check if I have the right solution. 2) 0.311g a) Molarity: 0.96 mol/l Percent concentration: 5.765% Parts per million ppm: 57650000 pmm thanks in advance
Radicals are atoms or molecules with an unpaired electron in their valence shell. So far, everything is clear. For example, an N atom is necessarily a radical, so one could say: atoms in an odd main group are generally radicals. But for example, with the oxygen atom: The s orbital and one p orbital are…
I need the redox function for a potato battery. I already know that iron (Fe) and water (H2O) need to be added to the redox, but I don't know how.
Can one say that the histone-DNA complex represents the tertiary structure in a way (secondary structure would then be the double helix of DNA, primary structure the sequence of nucleotides) …?
Why does solubility depend on temperature and ambient pressure?
Hey, I need help with the following kinetics problem: A k1 -> B k2 -> C. k1 and k2 are above the arrows. Now we need to create a graphic for this. What exactly does it look like? Thank you in advance.
Look at what a eutectic alloy is. You see that not the density determines the melting point, but the inner structure, the arrangement of the atoms.

The melting point has no connection with the density.Quecksilber has a higher density than iron and is liquid under standard conditions.
Density doesn’t have much to say. Especially since you compare a pure metal (alu) with an alloy (steel). That doesn’t make much sense either.
Lead has a high density and low melting point.
