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
Answer:
oxygen and hydrogen
Explanation:
the alcohol group is known as the -OH group, which has oxygen bonded to a hydrogen
A mirror is opaque, meaning that it reflects the light and images that shine on it's reflective surface.
The volume of the box is 8.6 × 10³ in².
<em>V = lwh</em> = 26 in × 18.4 in × 17.92 in = 8.6 × 10³ in²
<em>Note</em>: The answer can have only <em>two significant figures</em> because that is all you gave for the length of the box.
