Answer:
D. Strong nuclear force, electrostatic force, weak nuclear force, gravitational force
Answer:
a) The molecular mass of each compound dinitrogen pentaoxide is 108 g/mol.
b) The molecular mass of each compound lead(ll) nitrat is 331 g/mol.
c) The molecular mass of each compound calcium peroxide is 72 g/mol.
Explanation:
a) Molecular mass of dinitrogen pentaoxide that be M.
Mass of nitrogen atom = 14 g/mol
Mass of oxygen atom = 16 g/mol
b) Molecular mass of lead(ll) nitrate that be M.
Mass of lead = 207 g/mol
Mass of nitrogen atom = 14 g/mol
Mass of oxygen atom = 16 g/mol
c)Molecular mass of calcium peroxide that be M.
Mass of calcium atom = 40 g/mol
Mass of oxygen atom = 16 g/mol
I believe I know the answer to #4
ANSWER: Two moles to a first approximation
*Disclaimer* I'm pretty sure I'm right, but I could be wrong
I’m sorry I can barely see the question
He ability to rust is a chemical property of iron. The metal silver does not rust, but eventually a darker substance called tarnish forms on its surface. The chemical properties of copper cause it to become a blue-green color when it is exposed to air
