<span>Germane is the chemical compound with the formula GeH₄, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium.
</span>In chemistry, sigma bonds (σ bonds) are the strongest type of covalent chemical bond. They are formed by head-on overlapping between atomic orbitals. Sigma<span> bonding is most simply defined for diatomic molecules using the language and tools of symmetry groups.

To answer this question, we'll need the molar masses of nickel and vanadium:
Molar mass of nickel: 58.693g/mol
Molar mass of vanadium: 50.941g/mol
These values represent the mass of one mole of the element. A mole is the weight of Avogadro's number of atoms of an element (6.02 x 10^23 atoms).
We are given 58.693g of nickel, which is equivalent to one mole of nickel. Therefore, you will get the same number of atoms from one mole of vanadium, or 50.941g of vanadium.
Answer:
0.72
Explanation:
if 760=1
550=x
=550÷760= 0.72 in two s.f
