Answer:
ones with ionic bonds
Explanation:
they have high melting and boiling points
Answer : Option D) The particles move enough that they are not fixed in place, and the liquid can flow.
Explanation : The kinetic energy of the particles are allowed to move freely and are in motion when in the liquid state whereas the intermolecular particles can just flow; as the intermolecular attractions between the particles allows the liquid to flow by giving them a force to flow.
The empirical formula :
MgCl₂
Li₂O
<h3>Further explanation</h3>
Given
a 3.60 g of magnesium and 10.65 g of chlorine
b 9.1 g of lithium and 10.4 g of oxygen
Required
The empirical formula
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
a. mol ratio of Mg (Ar=24 g/mol) and Cl(Ar=35.5 g/mol)
Mg : Cl
=3.6/24 : 10.65/35.5
=0.15 : 0.3 = <em>divide by 0.15</em>
=1 : 2
The empirical formula : MgCl₂
b. a. mol ratio of Li (Ar=7 g/mol) and O(Ar=16 g/mol)
Li : O
=9.1/7 : 10.4/16
=1.3 : 0.65 = <em>divide by 0.65</em>
= 2 : 1<em> </em>
The empirical formula : Li₂O
The correct answer is realistic and reliable
The term used to describe the rapid release of bubbles, or rapid release of a gas from a liquid or a solution is called Effervescence. The bubbling of a solution is due to the escape of a gas which may be from a chemical reaction, as in fermenting liquid, or by coming out of a solution after having been under pressure, as in a carbonated drink. For example; soda, champagne among others.
