The correct answer is molecular formula = 2 x empirical formula
The given compound C2H10N2 is the molecular formula because the ratios of the elements are not reduced into lowest terms (empirical formula). To get the empirical formula, the ratios must be reduced to the smallest possible integral ratio which gives CH5N. As a result, the ratio between both formulas is 2.
Answer :
The steps involved in the electron-dot structure of given molecule are :
Step 1 : First we have to determine the total number of valence electron in a molecule.
Step 2 : Draw the skeleton of the molecule.
Step 3 : Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Step 4 : The rest of the electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the electron-dot structure.
All the electron-dot diagram of given molecule is shown below.
Answer:
what it does to those around you.
Answer:
A) 2.2 mol
Explanation:
Given data:
Number of moles of O₂ produced = ?
Number of moles of N₂O₅ decomposed = 4.3 mol
Solution:
Chemical equation:
2N₂O₅ → 4NO₂ + O₂
Now we will compare the moles of N₂O₅ and O₂.
N₂O₅ : O₂
2 : 1
4.3 : 1/2×4.3 = ×2.2
Thus, from 4.3 moles of N₂O₅ 2.2 moles of O₂ are produced.
1.22 litres will be the volume at a pressure of 1900 mm Hg if a gas occupies 3.06 liters at 760 mm Hg.
Explanation:
Data given:
Initial volume of the gas V1 = 3.06 Litres
Initial pressure of the gas P1 = 760 mm Hg
final pressure of the gas P2 = 1900 m Hg
final volume of the gas V2 =?
From the data we can see that Boyle's Law will be applied here,
P1V1 = P2V2
Rearranging the equation, we get
V2 =
putting the values in the equation, we get
V2 =
V2 = 1.224 Litres
The volume is 1.22 litres when the pressure is increased to 1900 mmHg.
