What type of reaction is required to bind two molecules of glycine together and release a molecule of water?​?
bulgar [2K]
<span>The glycine molecules can bind together and release a molecule of water by the process of condensation. Water would then be considered a by-product of the reaction. Condensation can also be seen when water in the air touches a container filled with cold liquid and you see water drops on the side of the glass.</span>

Molecular chlorine and molecular fluorine combine to form a gaseous product. Under the same conditions of temperature and pressu
uranmaximum [27]

Answer:

  • Cl F₃

Explanation:

<u>1) Reactants:</u>

The reactants are:

  • <em>Molecular chlorine</em>: this is a gas diatomic molecule, i.e. Cl₂ (g)

  • <em>Molecular fluorine</em>: this is also a gas diatomic molecule: F₂ (g)

<u>2) Stoichiometric coefficients:</u>

  • <em>One volume of Cl₂ react with three volumes of F₂</em> means that the reaction is represented with coefficients 1 for Cl₂ and 3 for F₂. So, the reactant side of the chemical equation is:

        Cl₂ (g) + 3F₂ (g) →

<u>3) Product:</u>

  • It is said that the reaction yields <em>two volumes of a gaseous product;</em> then, a mass balance indicates that the two volumes must contain 2 parts of Cl and 6 parts of F. So, one volume must contain 1 part of Cl and 3 parts of F. That is easy to see in the complete chemical equation:

       Cl₂ (g) + 3F₂ (g) → 2Cl F₃ (g)

        As you see, that last equation si balanced: 2 atoms of Cl and 6 atoms of F on each side, and you conclude that the formula of the product is ClF₃.
