Sodium chloride is composed of molecules that are stable when dry. In water, the atoms of the molecules separate from each other
astra-53 [7]

The molecules of Sodium chloride holds a chemical bond to become stable when dry is an ionic bond.

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

The chemical bonds are those which holds the atoms of molecules together and creates a temporary connection between them.

The three major types of chemical bonds are:

  • Ionic bonds
  • Covalent bonds
  • Metallic bonds

<h3>What are ionic bonds?</h3>

The ionic bonds generally occurs in between a metal and a nonmetal ions.

The atoms share electrons in between them to become stable, forms ions. Due to electric attraction between these ions forms a bond between them. That bond is called as Ionic bond.

<h3>The type of chemical bond in Sodium chloride:</h3>

Sodium chloride - NaCl

Where Na(sodium) forms Na⁺ ion(metal) by sharing electrons with the chlorine atom and Cl(chlorine) forms Cl⁻ ion(non-metal).

So, due to the attraction between the anion and the cation, a bond is established between them. So, it is called Ionic bond.

Therefore, the chemical bond in Sodium chloride is an Ionic bond.

a sample of sucrose was burned in a calorimeter, and 41,600 joules oh heat energy were released. which statement is true about t
Gala2k [10]

It absorbed 41,600 joules.

Explanation:

If the sample of sucrose burnt in the calorimeter releases 41600Joules of heat, then the water in the calorimeter will absorb 41600J.

 The heat lost by burning the sucrose in the calorimeter is also the heat gained by the water therein.

A calorimeter is a device by prevents heat loss to the environment in any form.

It is specially designed to minimize heat loss by conduction, convection radiation.

Therefore, since no heat is lost, the heat released by burning the sucrose is used in heating the water there.

In a redox reaction, how does the total number of electrons lost by the oxidized substance compare to the total number of electr
snow_lady [41]
The answer is (2) equal to. In redox reactions, you can't just lose electrons somewhere. If an electrons is lost by one, it must be gained by another. Hence, the importance of balancing redox reactions.
