Write a balanced half-reaction describing the oxidation of aqueous chloride anions to gaseous dichlorine.

Chemistry

dexar [7]3 years ago

Oxidation is a process which involves losing electrons in a reaction by an ion, atom or a molecule. It happens when the oxidation state of the ion, atom or the molecule is being increased. Chloride anions has an oxidation state of -1 and dichlorine has an oxidation state of zero or neutral charge. The balanced half-reaction would be written as:

2Cl- = Cl2 + 2e-

To balance the charge on both sides, two electrons should be produced or released by the anion form of chlorine. Being oxidized would mean that the charge of the ion or molecule is being increased. In this case, it is increased from -1 to 0.

<h3>What is ionic bond?</h3>

The main interaction in ionic compounds is ionic bonding, a type of chemical bonding that involves the electrostatic attraction between two atoms or ions with dramatically differing electronegativities. Along with metallic and covalent bonds, it is one of the most common types of bonds. Atoms (or collections of atoms) possessing an electrical charge are known as ions. Ions with negative charges are created when atoms gain electrons (called anions). Positively charged ions are produced when atoms lose electrons (called cations). In contrast to covalence, this electron transfer is referred to as electrovalence.

Ionic chemicals normally do not conduct electricity when solid, only when molten or in solution. Depending on the charge of the ions they are made of, ionic compounds typically have a high melting point.

Given the data you collected for the volume of water displaced by 25.000 g of aluminum, what is the density of aluminum?
vovikov84 [41]

Answer:

C. 2.70 g/mL

Explanation:

Density is the ratio between the mass of a substance and the volume it occupies. Based on Archimedes' volume, the displaced volume of the aluminium is the volume it occupies. To solve this question we must find the difference in volume between initial volume of water = 30mL and final volume of water + aluminium = 39.26mL. This difference is the volume of the aluminium. With its mass we can find density:

39.26mL - 30mL = 9.26mL

Density = 25.00g / 9.26mL =

2.70g/mL

Right answer is:

<h3>C. 2.70 g/mL </h3>
