There are 4.78 g of dry LICIO4 and
astraxan [27]

Answer:

The number of moles of H₂O is 0.135 mol.

The number of moles of LiClO₄ is 0.0449 mol.

Explanation:

Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.

The number of moles of a substance is calculated by:

\frac{mass of substance}{molecular weight of  substance}

To find the number of moles of H₂O:

Mass of H₂O in the sample = 2.43g

The molecular weight of H₂O = 18.02g

Number of moles = \frac{2.43}{18.02} = 0.135 mol.

To find the number of moles of LiClO₄:

Mass of LiClO₄ given = 4.78g

The molecular weight of LiClO₄ = 106.39g

Number of moles = \frac{4.78}{106.39} = 0.0449 mol.

How do my experiences affect the decisions/choices I make and my role as a citizen of the global community?
Lana71 [14]
Your experiences affect the decisions you make and your role because if your experiences weren’t as challenging as they are for others then your decisions will most likely point towards the easier choices. If you had challenging experiences then you will most likely make decisions that are more complex. You would know how hard a challenge is from experience so that would help you if your choices weren’t as easy as you thought they would be or as they are for others. This would affect your role in your community because if you had the chance to help out, you would probably pick the easiest task or the hardest task depending on your experiences.

Why is ionic bonding considered a bond type and an attractive force?
Anika [276]

Answer:

Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
