Question

1. Titanium crystallizes in a face centred cubic lattice.
It reacts with carbon or hydrogen interstitially by
allowing atoms of these elements to occupy holes
in the host lattice. Hydrogen occupies tetrahedral
holes but carbon occupies octahedral holes the
formula of titanium carbide and hydride are
plzz explain​

Answer 1

Answer:

Explanation:

Titanium carbide formula is TiC2

And titanium hydride formula is TiH

Explanation

Because as titanium crystallises in fcc there are 4 atoms per unit cell and as we know that the number of octahedral voids is twice the number of atoms so the number of carbon atoms is 8 and we get the formula Ti4C8 simplifying it we get TiC2

Tetralvoids is equal to the number of atoms or spheres so the number of hydrogen atoms is four and titanium also 4 we get the formula Ti4H4 simplying it we get TiH
