NO2 is a covalent compound
Answer:
1.204 × 10²³
Explanation:
The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.
To convert moles to atoms, multiply the molar amount by Avogadro's number.
(6.022 × 10²³) × 0.2
= 1.204 × 10²³
Explanation:
1)
a) Wavelength of red light = 700 nm
1 nanometer = 
Wavelength of red light in meter will be:

b) Wavelength of red light =

1 km = 3280.84 feet

1 foot = 0.1515152 chain


Value of distance in chains:

Answer:
C
Explanation:
Dalton's atomic theory are: Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass.
