energy source

Explanation:

After wire and filament have been connected, for the conduction of electricity, an energy source is required.

In the energy source, electrical energy is produced.

  • The energy source can be a simple electrochemical cell.
  • It can be a generator.
  • It can also be current from the national grid.
  • The energy source produces current which is carried in wire and it powers the filament

What is the density of a object whose dimensions are 5.54
Tcecarenko [31]

The object with dimensions 5.54\ cm \times 10.6\ cm \times 199\ cm and with mass 250.6 g will have a density equal to 0.02144\ g/cm^3.

<h3><u>Explanation:</u></h3>

<u>Given:</u>

Dimensions of the object = 5.54\ cm \times 10.6\ cm \times 199\ cm

length = l = 5.54 cm

width = w = 10.6 cm

height = h = 199 cm

Mass of the object = m = 250.6 g

<u>Formula:</u>

The relation between density, mass and volume of any object is given by:

Density = \frac{ Mass }{Volume}

Since volume of an object with length (l), width (w) and height (h) [assuming a rectangular object] can be defined as,

V = l \times w \times h =5.54 \times 10.6 \times 199

Volume = V = 11686.076\ cm^3

Density = Mass / Volume = \frac{250}{11686.076}

Density = 0.02144 g/cm^3

Density of the object is 0.02144 g/cm^3

Stock nomenclature nh4no3
dedylja [7]

Answer: Stock nomenclature of NH_4NO_3 is ammonium(I) nitrate

Explanation:

Stock nomenclature is used for chemical nomenclature where the oxidation states of some or all of the elements in a compound are indicated  by Roman numerals in parentheses.

For example:

FeCl_2 which has iron in oxidation state of +2 has stock nomenclature of iron(II) chloride.

FeCl_3 which has iron in oxidation state of +3 has stock nomenclature of iron(III) chloride.

Thus the stock nomenclature of NH_4NO_3 is ammonium(I) nitrate as ammonium has oxidation state of +1.
