How many σ and π bonds are present in a molecule of cumulene?
dimaraw [331]

A hydrocarbon with three or more consecutive (cumulative) double bonds is known as a cumulene. They are analogous to allenes, only exhibiting a more elongated chain. The basic molecule in this category is butatriene, which is also simply known as cumulene.  

In the structure of a cumulene, there are 3 double bonds and 4 single bonds. The double bond comprises 1 sigma bond, and 1 pi bond and 4 hydrogen bond produces a sigma bond with carbon. Thus, the molecule of cumulene comprises 7 sigma bonds and 3 pi bonds.

How many atoms are there in 144g of sucrose, C12H22O11 or sugar molecules?
kati45 [8]

Answer:

2.53×10²³ atoms

Explanation:

To solve this, convert grams to moles and moles to atoms.

To convert grams to moles, use the molar mass of C₁₂H₂₂O₁₁ (342.296 g/mol).  Divide the mass by the molar mass to get moles.  Moles = 0.4207

To convert moles to atoms, use Avogadro's number (6.022×10²³ atoms/mol).  Multiply moles by Avogadro's number to get atoms.  Atoms = 2.53×10²³

Which statement describes how chemical formula such as H20 represent compounds check all that apply
Allisa [31]
<h3>Answer:</h3>
  • They show the elements of make up a compound
  • They show the types of atoms that make up a molecule
  • They show the number of each type of atom in a molecule
<h3>Explanation:</h3>

To answer this question we need to know what is a compound.

  • A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
  • A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
  • Additionally, the chemical formula shows the number of each type of atom in a molecule.
  • In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.
