The thermal energy of a substance is related to the movement of the particles in the substance. This energy is defined by the temperature of the substance and whether heat is transferred or lost. This can be explained as a higher temperature causes the particles in substances to move faster and collide.

When a solution of sodium hydroxide is mixed with iron (II) chloride, a green precipitate is formed. What is the balanced equati

marshall27 [118]

The balanced chemical equation for the reaction is:

2NaOH(aq) + FeCl₂(aq) --> 2NaCl(aq) + Fe(OH)₂(s)

<h3>What is a chemical equation? </h3>

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

<h3>How to write the balanced equation </h3>

Sodium hydroxide => NaOH

Iron (II) chloride => FeCl₂

2NaOH(aq) + FeCl₂(aq) --> 2NaCl(aq) + Fe(OH)₂(s)

Which chemical equation is balanced to show that mass is conserved during the reaction? *

Mazyrski [523]

Answer:

Step-by-step explanation:

Equation B is balanced. It has four atoms of H and four of O on each side of the reaction.

A is <em>wrong</em>. It has two atoms of Cl on the left and only one on the right.

C is <em>wrong</em>. It has two atoms of O on the left and four on the right.

D is <em>wrong</em>. It has two atoms of Cl on the left and only one on the right.

Consider four different samples: aqueous NaBr, molten NaBr, aqueous NaF, and molten NaF. Current run through each sample produce

EastWind [94]

Answer:

Aqueous NaBr - oxygen gas

Molten NaBr - liquid bromine

Aqueous NaF- oxygen gas

Molten NaF - Flourine gas

Explanation:

In electrolysis process, anode is the positive electrode and cathode is the negative electrode.

Hence negative ions are attracted towards anode and gets oxidized.

When more than one type of ion is present , the ion which gets deposited is decided by the <u>discharge potential.</u>

Discharge potential is the voltage at which an ion is discharged.The ion that requires less energy to get deposited has low discharge potential.

Hence ion with low discharge potential gets deposited.

Discharge potential is in the order: $F^->Br^->OH^-$

In aqueous NaBr , there are two negative ions:Br- and OH-

OH- is oxidized to oxygen gas as OH- has lower discharge potential.

2. In molten NaBr, Br- is the only negative ion and liquid bromine is produced at anode.

3. In aqueous NaF, OH- and F- are the anions present. Clearly oxygen gas is produced at anode as OH- has lower discharge potential.

4. In molten NaF only anion present is F- and hence flourine gas is produced at anode.
