Having a large yard is an example of something that can promote sustainable development.

<h3>What is sustainable development ?</h3>

Sustainable development is an organizing principle for meeting human development goals while also sustaining the ability of natural systems to provide the natural resources and ecosystem services on which the economy and society depend.

A yard is an open place with fencing around it, with grasses and small shrubs. Having a large yard will not only meet the requirement of the human beings but also be in favor of environment as there will be no construction over that area.

What is the empirical formula for a substance if a 201.6 g sample of it contains 54.0 grams of nitrogen, 15.0 grams of hydrogen,
jeyben [28]

The empirical formula of the substance would be  NH_4Cl

<h3>Empirical formula calculation</h3>

The constituents of the compound are as follows:

N = 54/201.6 = 26.78% = 26.78/14 = 1.91 moles

H = 15/201.6 = 7.44% = 7.44/1 = 7.44 moles

Cl = 132.6/201.6 = 65.48% = 65.48/35.5 = 1.84 moles

Divide the number of moles by the smallest"

N = 1.91/1.84 = 1

H = 7.44/1.84 = 4

Cl = 1.84/1.84 = 1

Thus, the empirical formula is NH_4Cl

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
