Taking into account the reaction stoichiometry and definition of limiting reactant, AgNO₃ will be the limiting reagent.
Reaction stoichiometryIn first place, the balanced reaction is:
Cu + 2 AgNO₃ → 2 Ag + Cu(NO₃)₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Cu: 1 moleAgNO₃: 2 molesAg: 2 molesCu(NO₃)₂: 1 moleLimiting reagentThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
Limiting reagent in this caseTo determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 1 mole of Cu reacts with 2 moles of AgNO₃, 1.8 moles of Cu reacts with how many moles of AgNO₃?
[tex]amount of moles of AgNO_{3} =\frac{1.8 moles of Cux2 moles of AgNO_{3} }{1 mole of Cu}[/tex]
amount of moles of AgNO₃= 3.6 moles
But 3.6 moles of AgNO₃ are not available, 2 moles are available. Since you have less moles than you need to react with 1.8 moles of Cu, AgNO₃ will be the limiting reagent.
SummaryIn summary, AgNO₃ will be the limiting reagent.

What is an expression of Boyle's law (k = constant)?
A. V/T=K
B. V = kn
C. PV = k
D. Ptotal= P₁ + P₂ + P3 + &
Answer:
C.) PV = k
Explanation:
Boyle's Law is a variation of the Ideal Gas Law when all variables, except for pressure and volume, are held constant.
Pressure is represented by "P" and volume is represented by "V". In the Ideal Gas Law, pressure and volume are inversely proportional (if one goes up, the other goes down). That being said, the equation which best represents Boyle's Law is PV = k.
The graph shows the amount of a gaseous product formed over time during two trials of a reaction. A different concentration of a reactant was used during each trial while other factors were kept constant.
A graph is shown with two graph lines sloping upwards. The title on the x axis is Time and the title on the y axis is Amount of Product. The graph line with a steeper slope is labeled Trial 2 and the other is labeled Trial 1.
Which of the following statements explains which trial has a higher concentration of the reactant?
Trial 1, because the final amount of product formed is higher.
Trial 1, because this reaction lasted for a longer duration than Trial 2.
Trial 2, because this reaction was initially fast and slowed down later.
Trial 2, because the amount of product formed per unit time is higher.

What is a reaction?The term reaction has to do with the combination of reactants in order to yield products. Now we know that the reaction profile is used to show the interaction that exists between the reactants and the products.
The y-axis of the graph is for the amount while the x axis of the graph is the reaction time. The rate of reaction is the time taken for a given amount of products to appear or for a given amount of reactants to disappear.

A 10 M concentrated stock solution of NaCl is used to prepare 3 liters of diluted 1 M solution. Which of the following is true for the process used to achieve the required dilution?
The volume of stock solution used is less than 0.2 liters.
The volume of stock solution used is less than 3 liters.
The volume of the solvent used is less than 0.2 liters.
The volume of the solvent used is more than 3 liters.
Taking into account the definition of dilution, the answer is "The volume of stock solution used is less than 3 Liters."
DilutionWhen it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeVolume of stock solution usedIn this case, you know:
Ci= 10 MVi= ?Cf= 1 MVf= 3 LReplacing in the definition of dilution:
10 M× Vi= 1 M× 3 L
Solving:
Vi= (1 M× 3 L)÷ 10 M
Vi= 0.3 L
In summary, to prepare 3 Liters of 1 M solution, you need 0.3 L of the 10 M concentration stock solution and dilute to 3 L. Therefore, the answer is "The volume of stock solution used is less than 3 Liters."

The rate of the forward reaction equals the rate of the reverse reaction.
The rate of the forward reaction is slower than the rate of the reverse reaction.

What is dynamic equilibrium?When it comes to chemical reactions, a dynamic equilibrium is a condition in which a reversible reaction produces products and reactants at an equal rate.
Dynamic equilibrium can only be achieved in a closed system. That is, a system in which there are no external influences in form of energy, material, or pressure.
For example, consider the following reversible reaction:
[tex]A + B < --- > C + D[/tex]
If the reaction is in dynamic equilibrium, there will not be a net production of reactants and products. In other words, the rate of production of A and B will be the same as the rate of production of C and D.
This is as opposed to static equilibrium in which the production of both reactants and products stops completely after reaching equilibrium.

A 250 mL sample of gas is collected over water at 35°C and at a total pressure of 735 mm Hg. If the vapor pressure of water at 35°C is 42.2 torr, what is the volume of the gas sample at standard pressure?
Answer:
The volume of the gas sample at standard pressure is 819.5ml
Explanation:
Solution Given:
let volume be V and temperature be T and pressure be P.
[tex] V_1=250ml[/tex]
[tex] V_2=?[/tex]
[tex] P_{total}=735 mmhg[/tex]
1 torr= 1 mmhg
42.2 torr=42.2 mmhg
so,
[tex] P_{water}=42.2mmhg[/tex]
[tex] T_1=35°C=35+273=308 K[/tex]
Now
firstly we need to find the pressure due to gas along by subtracting the vapor pressure of water.
[tex] P_{gas}=P_{total}-P_{water} [/tex]
=735-42.2=692.8 mmhg
Now
By using combined gas law equation:
[tex]\frac{P_1*V_1}{T_1} =\frac{P_2*V_2}{T_2}[/tex]
[tex]V_2=\frac{P_1*}{P_2}*\frac{T_2}{T_1} *V_1[/tex]
[tex]V_2=\frac{P_gas}{P_2}*\frac{T_2}{T_1} *V_1[/tex]
Here [tex]P_2 \:and\: T_2[/tex] are standard pressure and temperature respectively.
we have
[tex]P_2=750mmhg \:and\: T_2=273K[/tex]
Substituting value, we get
[tex]V_2=\frac{692.8}{750}*\frac{273}{308} *250[/tex]
[tex]V_2= 819.51 ml[/tex]

on 1: A piece of unknown metal weighs 348 g. When the metal piece absorbs 6.64 kJ of heat, its temperature increases from 22.4 °C to 43.6 °C.
Answer:
.900 J / g-C°
Explanation:
I assume you are looking for the specific heat of the metal
Specific heat = J / g-C
= 6640 J / 348 g[ (43.6 - 22.4) ] = .900 J / g-C
The specific heat of the unknown metal is approximately [tex]\rm \( 0.90 \, \text{kJ/kg\°C} \)[/tex].
To find the specific heat of the unknown metal, we can use the formula:
[tex]\rm \[ q = m \cdot c \cdot \Delta T \][/tex]
where:
[tex]\rm \( q \)[/tex] = heat absorbed by the metal (in kJ)
[tex]\rm \( m \)[/tex] = mass of the metal (in g)
[tex]\rm \( c \)[/tex] = specific heat of the metal (in kJ/kg·°C)
[tex]\rm \( \Delta T \)[/tex] = change in temperature (in °C)
Given data:
[tex]\( m = 348 \, \text{g} \)\\\( \Delta T = 43.6°C \\\\- 22.4°C = 21.2°C \)\\\( q = 6.64 \, \text{kJ} \)[/tex]
Now, let's rearrange the formula to solve for [tex]\rm \( c \)[/tex]:
[tex]\rm \[ c = \frac{q}{m \cdot \Delta T} \][/tex]
Substitute the values:
[tex]\rm \[ c = \frac{6.64 \, \text{kJ}}{348 \, \text{g} \times 21.2°C} \][/tex]
Convert the mass to kg and temperature to °C:
[tex]\rm \[ c = \frac{6.64 \, \text{kJ}}{0.348 \, \text{kg} \times 21.2\°C} \]\\\\\ c \approx 0.90 \, \text{kJ/kg\°C} \][/tex]
The specific heat of the unknown metal is approximately [tex]\rm \( 0.90 \, \text{kJ/kg\°C} \)[/tex].
