Hello!

When aqueous solutions of Li₂SO₄ and NaI are mixed the following reaction occurs:

Li₂SO₄(aq) + 2NaI(aq) → 2LiI(aq) + Na₂SO₄(aq)

The compounds produced from this reaction are all soluble, so no precipitate is formed. We know that those compounds (LiI and Na₂SO₄) are soluble because of the solubility rules which states that salts from Group I elements (Li⁺, Na⁺) are soluble.

Have a nice day!

The salt that is formed during the reaction between potassium hydroxide and hydrochloric acid is
liubo4ka [24]

Answer:

Sodium chloride (NaCl)

Explanation:

According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.

Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.

For example: <u>Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)</u>

A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).

<em>The chemical equation for this Neutralization reaction:</em>

HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)

<u />

<u>Therefore, </u><u>sodium chloride (NaCl) is the salt formed</u><u> during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).</u>

Calcium (Ca) and diatomic oxygen (O2) combine to form calcium oxide (CaO). The data table below compares the properties of these
Elenna [48]

A chemical reaction occurred because calcium oxide has different properties than calcium and diatomic oxygen. The correct option is A.

<h3>What are chemical reactions?</h3>

A chemical reaction is said to occur when the chemical properties of substances change during the course of the reaction.

From the illustration, the chemical properties of calcium oxide are unique from that of calcium and oxygen. Thus, calcium oxide has become a new substance entirely.

Once a reaction leads to the formation of new substances, such a reaction is a chemical reaction.

The molar heat capacity of a compound with the formula C2H6SO is 88.0 J/mol-K. The specific heat of this substance is __________
lisabon 2012 [21]

Answer : The specific heat of this substance is, 1.13 J/g.K

Explanation :

Molar heat capacity : It is defined as the amount of heat absorbed by one mole of a substance to raise its temperature by one degree Celsius.

As we are given that the chemical formula of compound is, C_2H_6SO

First we have to calculate the molar mass of given compound.

Molar mass of C_2H_6SO = 2(12g/mol)+6(1g/mol)+32g/mol+16g/mol

Molar mass of C_2H_6SO = 78 g/mol

Now we have to calculate the specific heat of this substance.

Specific heat of this substance = \frac{\text{Molar heat capacity of a compound}}{\text{Molar mass of }C_2H_6SO}

Specific heat of this substance = \frac{88.0J/mol.K}{78g/mol}

Specific heat of this substance = 1.13 J/g.K

Thus, the specific heat of this substance is, 1.13 J/g.K
