Answer:

A. Four C–H single bonds and two O=O double bonds.

Explanation:

  • The chemical reaction proceeds with breaking bonds in the reacting molecules and forming new bonds in the products.
  • In this reaction four single bonds are broken in CH₄ and two double bonds O=O are broken in two molecules of O₂.
  • Also, two double bonds C=O are formed in CO₂ molecules and 4 single bonds O–H are formed in 2 molecules of H₂O <em>(each molecule contain 2 new bonds)</em>.
  • <em>So, A is the right answer.</em>

The methane molecule undergoes oxidation and the carbon is oxidized to carbon dioxide and hydrogen to water.

In this reaction there is cleavage of four C-H bonds and two O=O bonds

there will be formation of two C=O bonds and four O-H bonds.

Overall due to more bond cleavage energy there will be evolution of energy. thus combustion is an exothermic reaction.

What is the molarity of a solution that contains 17g of NH₃ in 0.50L of solution?
erastovalidia [21]

Explanation:

Because molarity is mol/L, we'll have to convert 17g to mol.

After obtaining the mol, we'll divide that by the volume to obtain Molarity.
