We are given with the mass of Arsine (
The mass of arsine is 15g
there is a relation between moles, mass and molar mass of any compound which is
The molar mass of Arsine = atomic mass of As + 3X atomic mass of H
the molar mass of Arsine = 74.92 + 3X 1 = 77.92 g/mol
Let us calculate the moles as
Answer:
B and C is corrent i got it right on edge
Explanation:
Answer:
Since the melting point of iron (1538 C) is higher than the Curie point (770 C), the recast iron will lose its original magnetism. After the iron has cooled below the Curie point, it can be re-magnetized.
B, kilo stands for thousand so 1 KILOmetre is = to 1000 metres
