Answer:
1ans:-The solid formed by directly cooling a gaseous substance through a process of sublimation is known as sublimate.
2ans:-The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons.
3ans:-
Potassium permanganate/Formula
IUPAC ID: Potassium manganate(VII)
Molar mass: 158.034 g/mol
Soluble in: Water.
4ans:-Haber himself initially used catalysts based on osmium and uranium. Uranium, however, reacts to its nitride during catalysis and osmium oxide is rare. Due to the comparatively low price, high availability, easy processing, lifespan and activity, iron was ultimately chosen as catalyst.
5ans;-Covalent bonding
It is the mutual attraction of the atoms' nuclei (which are positively charged) for the shared electrons (negatively charged) that hold the bond together. For example, carbon and hydrogen atoms share electrons to form covalent bonds in methane, CH4.
