Given:

Initial Volume \sf (V_1) = 11.2 L

Initial Pressure \sf (P_1) = 0.860 atm

Final Volume \sf (V_2) = 15.0 L

To Find:

Final Pressure \sf (P_2)

Concept/Theory:

\bf{ \underline{Boyle's  \: Law} \:  (Pressure  - Volume \:  Relationship)}

"At constant temperature, the pressure of a fixed amount of gas varies inversely with the volume of the gas."

\bf{P \propto \dfrac{1}{V}  \: (at \:  constant \:  T \:  and \:  n)}

It can be also stated as "At constant temperature, the product of pressure and volume of fixed amount of a gas remains constant."

\bf{PV = Constant}

If the initial pressure and volume of a fixed amount of gas at constant temperature are \sf (P_1) & \sf (V_1) and final pressure of the gas is \sf (P_2) and volume occupied is \sf (V_2), then according to Boyle's law;

\bf{P_1V_1 = P_2V_2 = Constant}

OR

\bf{\dfrac{P_1}{P_2} = \dfrac{V_2}{V_1}}

Answer:

By using Boyle's Law, we get:

\rm \longrightarrow \dfrac{0.860}{P_2} = \dfrac{15.0}{11.2} \\  \\ \rm \longrightarrow P_2 =  \dfrac{11.2}{15.0}  \times 0.860 \\  \\  \rm \longrightarrow P_2 =  \dfrac{9.632}{15.0}  \\  \\ \rm \longrightarrow P_2 = 0.642 \: atm

\therefore Final Pressure \sf (P_2) = 0.642 atm

Answer:

<h2>0.642 atm </h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question we have

P_2 =  \frac{11.2 \times 0.86}{15}  =  \frac{9.632}{15}  \\  = 0.64213333...

We have the final answer as

<h3>0.642 atm</h3>

Hope this helps you

A 4.0 L container holds a sample of hydrogen gas at 306 K and 150 kPa. If the pressure increases to 300 kPa and the volume remai
riadik2000 [5.3K]

Answer:

612 K

Explanation:

From the question given above, the following data were obtained:

Initial temperature (T₁) = 306 K

Initial pressure (P₁) = 150 kPa

Final pressure (P₂) = 300 kPa

Volume = 4 L = constant

Final temperature (T₂) =?

Since the volume is constant, the final (i.e the new) temperature of the gas can be obtained as follow:

P₁ / T₁ = P₂ / T₂

150 / 306 = 300 / T₂

Cross multiply

150 × T₂ = 306 × 300

150 × T₂ = 91800

Divide both side by 150

T₂ = 91800 / 150

T₂ = 612 K

Thus, the new temperature of the gas is 612 K

Consider the formula for glucose: C6H12O6. What does this indicate about the relationship of the reactants to glucose?
stellarik [79]

The correct option is D.

The reactants that combine together to form glucose are carbon dioxide, water and energy from the sun. Six molecules of carbon dioxide combine with six molecules of water in the presence of sunlight to form glucose. The chemical equation for the reaction is given below"

6CO2 + 6H2O + Sunlight = C6H12O6.
