Answer:

Ionic bonding occurs between atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons. Covalent bonding occurs between atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.

How many molecules are there in 31.8 moles of water?

Murljashka [212]

Answer:

$31.8\ moles = 1.91 * 10^{25}\ molecules$

Explanation:

Given

31.8 moles of water

Required

Determine the number of molecule

In standard units: 1 molecule of water is:

$1\ mole = 6.022 * 10^{23}\ molecules$

Multiply both sides by 31.8

$31.8 * 1\ mole = 31.8 * 6.022 * 10^{23}\ molecules$

$31.8\ moles = 31.8 * 6.022 * 10^{23}\ molecules$

$31.8\ moles = 191.4996 * 10^{23}\ molecules$

Express 191.4996 as a standard form

$31.8\ moles = 1.914996 * 10^2 * 10^{23}\ molecules$

Apply law of indices:

$31.8\ moles = 1.914996 * 10^{2+23}\ molecules$

$31.8\ moles = 1.914996 * 10^{25}\ molecules$

Approximate:

$31.8\ moles = 1.91 * 10^{25}\ molecules$

6 Li + Zn3(PO4)2 ------- > 2 Li3PO4 + 3 Zn

bogdanovich [222]

Moles of Lithium phosphate : 0.495

<h3>Further explanation</h3>

Given

6 Li + Zn₃(PO₄)₂ ------- > 2 Li₃PO₄ + 3 Zn

Required

Moles of Lithium phosphate

Solution

moles of Zinc(Ar=65,38 g/mol) :

= mass : Ar

= 48.6 : 65.38

= 0.743

From equation, mol ratio of Zn : Li₃PO₄ = 3 : 2, so mol Li₃PO₄ :

= 2/3 x mol Zn

= 2/3 x 0.743

= 0.495
