Mass of SnF₂ produced : 35.634 g
<h3>Further explanation</h3>
Reaction
Sn+2HF⇒SnF₂+H₂
mol Sn (Ar 118.710 g/mol) :
mol SnF₂ = mol Sn = 0.379
mass SnF₂ (MW=156.69 g/mol) :
⇒theoretical
Answer:
Density = mass/ volume
Explanation:
57.4g / 11.5cm3 = 4.991304(g/cm)
round to sig figs = 5.00(g/cm)
Option (C) Electron.
Explanation:
Because Vander wall forces arises due to the small moment when a temporary dispole is created between the atoms. The more the electron the stronger the polarization will be and hen stronger bond.
Answer: The study of elements and their compounds and reactions with one another.
Explanation: ACTUAL DEFINITION (Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.)
A change of 1 Kelvin is exactly the same as a change of 1 degree Celsius.
