olchik [2.2K]4 years ago
6 0

Answer:

1.00 mole of He have 6,02x10^{23} atoms.

Explanation:

To solve this exercise it is important to know the definition of Avogadro's number

Avogadro's number is the proportional factor that relates the molar mass of a substance to the number of elementary units (atoms, molecules, particles, ions, electrons) that constitute it and its magnitude is equal to 6.022 140 857 × 10²³

One mole of helium we have 6,02x10^{23} atoms.

Briefly explain the source, harmful effects and physical properties of oxides of <br> nitrogen.
kondaur [170]

Answer:

Nitrogen reacts with oxygen to form a number of nitrogen oxides. It exhibits different oxidation states in its oxides, ranging from +1 to +5. Oxides of nitrogen having nitrogen in the higher oxidation state are more acidic than that in lower oxidation state. Nitrogen oxides are critical components of photochemical smog. They produce the yellowish-brown colour of the smog. In poorly ventilated situations, indoor domestic appliances such as gas stoves and gas or wood heaters can be significant sources of nitrogen oxides.

Following are the harmful effects caused by the oxides of nitrogen

Nitrogen oxides causes irritation in mucous membrane.

Large concentrations of Nitrogen oxide causes lungs problems in humans

It causes injuries to vegetation by damaging leaves.

Nitrogen oxide oxidizes Hydrocarbons in the presence of sunlight, which causes eye irritation, asthama attacks, nasal and throat infections.

NO: sharp, sweet-smelling, colourless gas. Melting point: -163.6°C. Boiling point: -151.8°C. Relative Density: 1.04 (air = 1) NO2: reddish-brown gas with irritating odour
