Explain the solid, liquid, and gas states in terms of volume, shape and movement of particles

Chemistry
1 answer:
Leni [432]3 years ago
4 0

Solids have one static volume and shape and particles of solids move a short distance, practically against each other, before hitting one another.

Liquids fill the volume and take the shape of the container they are placed in and particles move a longer distance before hitting one another and bouncing back to each other

Gases fill shape and volume of their container and their particles move freely about a larger space than either solid or liquid and hit one another bouncing

In general, atomic radii:
Artist 52 [7]

<u>Answer:</u> The correct answer is Option E.

<u>Explanation:</u>

Atomic radius is defined as the total distance measured from the nucleus of an atom to the outermost shell.

<u>Trend down the group:</u>

Moving from top to bottom, a new shell gets add up around the nucleus and the outermost shell gets far away from the nucleus. Due to this, the distance between the nucleus and outermost shell increases, which results in the increase of atomic radii of the atom.

<u>Trend across the period:</u>

Moving from left to right in a period, more and more electrons gets add up in the same shell. The attraction between the last electron and the nucleus increases. This results in the shrinkage of size of an atom. Thus, decreasing the atomic radii of the atom.

Hence, the correct answer is Option E.

An HCl solution has a concentration of 0.09714 M. Then 10.00 mL of this solution was then diluted to 250.00 mL in a volumetric f
aivan3 [116]

Answer:

a. 3.8856x10⁻³M HCl

b. 1.23x10⁻⁴M OH⁻

c. 1.23x10⁻⁴M Ag⁺

d. Ksp = [Ag⁺] [OH⁻]

Explanation:

a. The reaction that you are studying is:

HCl(aq) + AgOH(aq) → H₂O(l) + AgCl(s)

The HCl solution is diluted from 10.00mL to 250.00mL, that is:

250.00mL / 10.00mL = <em>25 -The solution is diluted 25 times-</em>

As original concentration of HCl is 0.09714M, the concentration of the diluted solution is:

0.09714M / 25 =

<h3>3.8856x10⁻³M HCl</h3><h3 />

b. 1 mole of HCl reacts per mole of AgOH, moles of HCl that reacts are:

7.93mL = 7.93x10⁻³L × (3.8856x10⁻³mol HCl / L) = 3.0813x10⁻⁵ moles of HCl.

Based on the reaction, you have in solution

<em>3.0813x10⁻⁵ moles of AgOH = Ag⁺ = OH⁻</em>

The AgOH solution was 250.0mL = 0.2500L, its concentration is:

3.0813x10⁻⁵ moles OH⁻ / 0.2500L =

<h3>1.23x10⁻⁴M OH⁻</h3><h3 />

c. In solution, AgOH produce Ag⁺ and OH⁻ in equals proportions, that means:

1.23x10⁻⁴M OH⁻ =

<h3>1.23x10⁻⁴M Ag⁺</h3><h3 />

d. The solubility product reaction of AgOH(s) is:

AgOH(s) ⇄ Ag⁺(aq) + OH⁻(aq)

Where Ksp for this reaction is defined as:

<h3>Ksp = [Ag⁺] [OH⁻]</h3>

Sulfur reacts with oxygen to form sulfur dioxide (SO2(g), mc010-1.jpgHf = –296.8 kJ/mol) according to the equation below. mc010-
BlackZzzverrR [31]
We want: 
S(s) + O2(g) --> SO2(g) 
So the following are the given:
1) S(s) + 3/2O2(g) --> SO3(g) ∆H = -395.8 kJ/mole 
2) 2SO2 + O2 --> 2SO3(g) ∆H = -198.2 kJ/mole 
Reverse Equation 2) and then  divide by 2 
SO3(g) --> SO2(s) + 1/2O2(g) ∆H = +99.1 kJ/mole 
Add Equation 1) 
S(s) + O2(g) --> SO2(g) ∆H = -296.7 kJ/mole

Can someone please help me
Vanyuwa [196]

Answer:

1.7

Explanation:

Density = M/V

When you divide 4.52 by 2.6, you get 1.738461538, which can be simplified to 1.7.
