C₁₀H₁₄N₂ is the empirical formula.

In chemistry, the empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound.

<h3>Tell us about the empirical formula.</h3>

The empirical formula of a chemical compound in chemistry is the simplest whole number ratio of atoms in a compound. Two simple instances of this concept are the empirical formulas of sulfur monoxide (SO) and disulfur dioxide (S2O2).

Its empirical formula is the simplest whole number ratio of each type of atom in the compound. Data about the mass of each component in a compound or the composition's percentage can be used to calculate it.

Draw the products obtained when 3,3,6-trimethylcyclohexene is treated with nbs and irradiated with uv light.
Jlenok [28]

Answer:

See explanation below

Explanation:

First to all, you need to know what is the function of NBS.

N-Bromosuccinimide (NBS) is a brominating and oxidizing agent that is used as source for bromine in radical reactions (for example: allylic brominations) and various electrophilic additions.

In this case, when it's present the light or heat, this agent acts as electrophylic addition, so, instead of going to the double bond, it's going to do an allylic bromination, so the possible products are the following: (See picture)

Cyanogen is a gas which contains 46.2% C and 53.8% N by mass. At a temperature of 25°C and a pressure of 750 mm Hg, 1.50 g of cy
sergiy2304 [10]

Answer:

Molecular formula of cyanogen is C₂N₂

Explanation:

We apply the ideal gases law to find out the mole of cyanogen

P . V =  n. R. T

Firstly let's convert the pressure in atm, for R

750 mmHg = 0.986 atm

25°C + 273 = 298K

0.986 atm . 0.714L = n . 0.082 L.atm/mol.K .298K

(0.986 atm . 0.714L) / (0.082 L.atm/mol.K .298K) = n

0.0288 mol = n

Molar mass of cyanogen = mass / mol

1.50 g /0.0288 mol = 52.02 g/m

Let's apply the percent, to know the quantity of atoms

100 g of compound contain 46.2 g of C and 53.8 g of N

52.02 g of compound contain:

(52.02 . 46.2) / 100 = 24 g  → 2 atoms of C

(52.02 . 53.8) / 100 = .28 g  →  2 atoms of N

The Andes Mountains are found along the western coast of South America. Which kind of plate boundary is responsible for this mou
lozanna [386]

The Nazca plate is converging with the South American plate.

Explanation:

The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.

This mountain range typifies the geology and geography of the South American continent.

  • Along this convergent margin, one plate subducts beneath the other.
  • The oceanic plate due to its density goes into the mantle.
  • The causes the continent riding to obduct and be forced.
  • With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.
