Aluminum is light and is quite unreactive it is malleable and strong too.
Answer:
I think is the last one!!!! punnet square ⬜
Explanation:
Both melting and boiling point of water are much higher that that of H2S.
The MP and BP of water are 0°C and 100°C respectively whereas the MP and BP of H2S are -82°C and -60°C respectively.
Clearly, the intermolecular forces in H2O are much stronger than in H2S because, H2O has hydrogen bonding in it, which is both inter and intra. Whereas H2S has only weak van der waal force between their molecules. This is why boiling and melting points of H2O is more than that of H2S.
Hydrogen bonding is a particular type of dipole-dipole association which occurs between atoms of hydrogen bound to strongly electronegative atoms that are either fluorine, oxygen or nitrogen.
The hydrogen atom's partially positive side is drawn to the partially negative end of these atoms found in some other molecule. It is a strong binding mechanism between the molecules.
Answer:
The answer to your question is: P2 = 846 kPa
Explanation:
Data
V1 = 2.5 l
P1 = 300 kPa
T1 = 273 °K
P2 = ?
V2 = 1 l
T2 = 308°K
Formula
P2 = 846 kPa
<span>The number of lone electron pairs on the central atom of molecule having a linear molecular geometry such as CIF2- is three (3). In studying chemistry, linear molecular geometry describes the geometry around a central atom bind to two other atoms or ligands placed to a bond-angle of 180 degrees.</span>
