Answer:

T₁ = 563.19 K

Explanation:

Given data:

Initial volume = 359 mL

Final volume = 269 mL

Final temperature = 422 K

Initial temperature = ?

Solution:

The given problem will be solve through the Charles Law.

Charles Law:

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₁ = V₁T₂ / V₂

T₁ = 359 mL × 422 K / 269 mL

T₁ = 151498 mL.K / 269 mL

T₁ = 563.19 K

Which equation best describes the net changes based upon the observation that solid silver nitrate and solid potassium chloride
stealth61 [152]

Answer:

The correct option is: AgNO₃(aq) + KCl(aq) = AgCl(s) + KNO₃(aq)  

Explanation:

Precipitation reaction is a chemical reaction that involves reaction between <em>two soluble salts to give an insoluble salt.</em> This <u>insoluble salt exists as a solid</u> and settles down.

Therefore, the solid formed in a precipitation reaction is known as the precipitate.  

As the solid silver nitrate (AgNO₃) and solid potassium chloride (KCl) are <u>soluble in water</u>, therefore, their aqueous solutions are represented as AgNO₃(aq) and KCl(aq), respectively.

The precipitation reaction of AgNO₃(aq) and KCl(aq) gives an <u>insoluble salt, silver chloride (AgCl) and a soluble salt, potassium nitrate (KNO₃).</u>

The insoluble salt, <u>AgCl is called the precipitate</u> and is represented as AgCl(s). Whereas, the <u>soluble salt</u>, KNO₃ is represented as KNO₃ (aq).

<u>Therefore, the chemical equation for this precipitation reaction is:</u>

AgNO₃(aq) + KCl(aq) → AgCl(s) + KNO₃(aq)

Sort each of the following events based on whether the solubility of the indicated gas will increase, decrease, or stay the same
STatiana [176]

The answers are: 1) decrease 2) increase 3) decrease 4) increase 5) increase

<h3>FURTHER EXPLANATION</h3>

The following factors affect the solubility of gases in liquids:

1. Temperature - inverse relationship

<em>As the temperature is increased, the gas particles gain energy and start to move faster. This enables them to escape the liquid leading to decrease in the solubility of the gas. </em>

2. Partial Pressure of gas - direct relationship

<em>According to Henry's Law, for a given temperature, the solubility of the gas and the partial pressure of the gas above the liquid are proportional. With the application of pressure on the gas above the liquid, the gas particles are forced to move into the solvent.</em>

<em />

1. Temperature is increased - gas solubility decreases (Factor 1)

2. Partial pressure of an anesthetic gas is increased - gas solubility increases  (Factor 2)

3. O2: temperature of a body of water rises - gas solubility decreases (Factor 1)

4. Pressure of a gas over a solvent is increased - gas solubility increases (Factor 2)

5. Air in blood: a diver descends 10 m and the pressure increase by 1 atm - gas solubility increases (Factor 2)

<em>As the diver goes deeper, the pressure increases and more gases dissolve in the diver's blood. As the diver ascends, he or she must do so slowly to ensure that this large amount of gas is removed from the blood gradually otherwise, the diver might suffer from decompression sickness.</em>

What moving faster a golf ball or bowling ball
anygoal [31]
This all depends on lots of independent variables such as force used to roll the ball, wind resistance, etc. With no variables included, they would both move at the same velocity.
