Which substances have the lowest melting points: ionic covalent, or metallic

Chemistry
1 answer:
const2013 [10]3 years ago
5 0

Answer:

Covalent  

Step-by-step explanation:

Covalent substances have relatively weak intermolecular forces. Many covalent substances such as hydrogen and oxygen are gases at room temperature, so they have low melting points.

<em>Ionic substances</em> have strong ion-ion attractive forces, and <em>metals </em>have strong metallic (electron-metal cation) attractions. I don't know of any metals or ionic compounds that are gases at normal conditions.

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation
Bad White [126]
<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>

How many grams of NH3 can be dissolved in 50 grams of water at 50oC?
weqwewe [10]

15 grams of  NH3 can be dissolved

<h3>Further explanation</h3>

Given

50 grams of water at 50°C

Required

mass of NH3

Solution

Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility  

  • 1. Temperature:
  • 2. Surface area:
  • 3. Solvent type:
  • 4. Stirring process:

We can use solubility chart (attached) to determine the solubility of NH3 at 50°C

From the graph, we can see that the solubility of NH3 in 100 g of water at 50 C is 30 g

So that the solubility in 50 grams of water is:

= 50/100 x 30

= 15 grams
