Answer:

Covalent bonds.

Explanation:

They can also be called molecular bond as it is a chemical bond that involves electron sharing between pairs of atoms.  The said electron pairs are known to be shared pairs or bonding pairs, which stable balance of attractive and repulsive forces amongst atoms, when electrons are been shared, is known as covalent bonding.

They are way more common in organic chemistry than in ionic bonds.

In matter results in a change in its identity and properties.
FrozenT [24]

Answer:

The chemical change in matter is results in a change in its identity and properties.

Explanation:

There are toe type of changes physical change and chemical change.

The chemical change change in matter lead to lost its identity and properties.

Chemical change:

The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.

These changes are irreversible

These changes occur due to chemical reactions

These may not be observed with naked eye

Example:

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

Boiling of egg: that change the chemical composition of protein in the egg .

The reaction of Hydrogen and oxygen:  

H 2 (g)  + O 2  (g) -------------------------------------> 2H 2O  (l)

An object has a mass of 441 g and a volume
Ratling [72]

Answer:

<h3>The answer is 4.41 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{441}{10}  \\

We have the final answer as

<h3>4.41 g/cm³</h3>

Hope this helps you
