Answer:

A gas that exerts a pressure of <u><em>583.33 psi.</em></u> psi in a container with a volume of 12.45 L will exert a pressure of 1112 psi when transferred to a container with a volume of 6.531 L.

Explanation:

Initial pressure exerted by the gas = P_1

Initial volume occupied by the gas = V_1=12.45 L

Final pressure exerted by the gas = P_2=1112 psi

Final volume of the gas occupied by the gas = V_2=6.531 L

Applying Boyle's law:

P_1\times V_1=P_2\times V_2

P_1=\frac{P_2\times V_2}{V_1}=\frac{1112 psi\times 6.531 L}{12.45 L}=583.33 psi

The initial pressure exerted by the gas was 583.33 psi.

A gas that exerts a pressure of <u><em>583.33 psi.</em></u> psi in a container with a volume of 12.45 L will exert a pressure of 1112 psi when transferred to a container with a volume of 6.531 L.

Here, we may apply Boyle's law, which is mathematically expressed as:
PV = constant
So, we equate the product of the the initial pressure and volume to the product of the final pressure and volume as such:
P * 12.45 = 1112 * 6.53
P = (1112 * 6.53) / 12.45
P = 583.2 PSI

dlinn [17]

<u>Answer:</u> The unbalanced chemical equation is written below.

<u>Explanation:</u>

Unbalanced chemical equation does not follow law of conservation of mass.

In an unbalanced chemical equation, total number of individual atoms on the reactant side will not be equal to the total number of individual atoms on the product side.

The chemical equation for the reaction of diboron trioxide and magnesium metal follows:

B_2O_3(s)+Mg(s)\rightarrow B(g)+MgO(s)

Hence, the unbalanced chemical equation is written above.

How to calculate delta S surroundings? calculate Delta S(surr) at the indicated temperature for a reaction having each of the fo
astraxan [27]
You can use the equation ΔS(surr)=q(surr)/T or ΔS(surr)=-q(rxn)/T.
the two equations are equal since we know that the energy the system (reactoin) puts out just goes into the surroundings.  
(In other words q(surr)=-q(rxn))

Using the equation, <span>ΔS(surr)=-(-283kJ/298K)=0.9497kJ/K or 949.7J/K

This answer makes sense since the reaction is exothermic which means it released energy into the system which usually causes the entropy to increase.

I hope that helps.</span>

A bomb calorimeter has a heat capacity of 783 J/oC and contains 254 g of water whose specific heat capacity is 4.184 J/goC. How
IrinaK [193]

Answer : The amount of heat evolved by a reaction is, 4.81 kJ

Explanation :

Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water

q=[q_1+q_2]

q=[c_1\times \Delta T+m_2\times c_2\times \Delta T]

where,

q = heat released by the reaction

q_1 = heat absorbed by the calorimeter

q_2 = heat absorbed by the water

c_1 = specific heat of calorimeter = 783J/^oC

c_2 = specific heat of water = 4.184J/g^oC

m_2 = mass of water = 254 g

\Delta T = change in temperature = T_2-T_1=(23.73-26.01)=-2.28^oC

Now put all the given values in the above formula, we get:

q=[(783J/^oC\times -2.28^oC)+(254g\times 4.184J/g^oC\times -2.28^oC)]

q=-4208.28J=-4.81kJ

Therefore, the amount of heat evolved by a reaction is, 4.81 kJ
