The reaction a(g)⇌b(g) has an equilibrium constant of 5.8 and under certain conditions has q = 336. part a what can you conclude about the sign of δg∘rxn and δgrxn for this reaction under these conditions?

Answers

Answer:

The answer is "As [tex]Q=336[/tex], at high-temperature [tex]\Delta G_{rxn}>0[/tex] and When[tex]K>1,[/tex][tex]\Delta G^{\circ}_{rxn}>0[/tex]."

Explanation:

The equation for the reaction is:

[tex]A(g) \leftrightharpoons B(g)[/tex]  

[tex]K=5.8\\\\Q=336[/tex]

At equilibrium,

[tex]\Delta G^{\circ}_{rxn}>0[/tex][tex]=-RT \ln \ K[/tex]

When k=5.8(>1), the value of [tex]\ln k[/tex] would be positive

So, [tex]\Delta G^{\circ}_{rxn}[/tex] is negative (< 0)

So if K > l, [tex]\Delta G^{\circ}_{rxn}<0[/tex]

If the reaction is not in equilibrium so the equation is :

[tex]\Delta G_{rxn}>0[/tex]=[tex]\Delta G^{\circ}_{rxn}[/tex][tex]+RT \ln Q[/tex]

Substituting the expression:

[tex]\Delta G_{rxn}>0[/tex][tex]= (-RT \ln K) + RT \ln Q[/tex]

                 [tex]= RT(\ln Q- \ln K)\\= RT(\ln (336)-\ln (5.8))\\= RT(4.06)[/tex]

It is the positive value for all temperatures.

So, As Q = 336, at the high temperature [tex]\Delta G_{rxn}>0[/tex].

If 164.8 g of iodine monobromide is combined with 62.4 g of ammonia, determine the amount of excess reactant that remains after the reaction is completed and the percentage yield of nitrogen triiodide if 96.4 is produced?

Answers

Answer:

[tex]m_{NH_3}^{leftover}=57.88g[/tex]

[tex]Y= 92.0\%[/tex]

Explanation:

Hello there!

In this case, according to the following chemical reaction between iodine monobromide and ammonia:

[tex]3IBr+NH_3\rightarrow NI_3+3HBr[/tex]

It turns out firstly necessary to identify the limiting reactant, by considering the proper molar masses and the 3:1 and 1:1 mole ratios of iodine monobromide to nitrogen triiodide and ammonia to nitrogen triiodide respectively:

[tex]n_{NI_3}^{by\ IBr}=164.8gIBr*\frac{1molIBr}{206.81gIBr}*\frac{1molNI_3}{3molIBr} =0.266molNI_3\\\\n_{NI_3}^{by\ NH_3}=62.4gNH_3*\frac{1molNH_3}{17.03gNH_3}*\frac{1molNI_3}{1molNH_3} =3.66molNI_3[/tex]

Thus, we conclude that the limiting reactant is IBr as is yields the fewest moles of nitrogen triiodide product. Next, we can calculate the reacted grams of ammonia as the excess reactant:

[tex]m_{NH_3}^{reacted}=0.266molNI_3*\frac{1molNH_3}{1molNI_3}*\frac{17.03gNH_3}{1molNH_3}=4.52gNH_3[/tex]

And therefore the leftover of ammonia is:

[tex]m_{NH_3}^{leftover}=62.4g-4.52g=57.88g[/tex]

Next, the percent yield is calculated by firstly calculating the theoretical yield of nitrogen triiodide as follows:

[tex]m_{NI_3}^{theoretical}=0.266molNI_3*\frac{394.72gNI_3}{1molNI_3} =104.8gNI_3[/tex]

And finally the percent yield by dividing the given actual yield of 96.4 g by the previously computed theoretical yield:

[tex]Y=\frac{96.4g}{104.8g}*100\%\\\\Y= 92.0\%[/tex]

Explanation:

La capacidad de un elemento de existir en diferentes formas en el mismo estado físico se conoce como alotropía.

No es solo el carbono el que exhibe alotropía. También se sabe que el azufre y el fósforo exhiben alotropía.

Hay dos alótropos cristalinos de azufre; grafito y diamante. El grafito y el diamante difieren en la disposición de los átomos de carbono y la naturaleza de los enlaces entre los átomos de carbono en ambas sustancias.

Por lo tanto, el grafito y el diamante tienen propiedades físicas y químicas observadas completamente diferentes debido a las diferencias en la disposición de los átomos de carbono en cada sustancia, así como a las diferencias en la naturaleza de los enlaces entre los átomos de carbono en ambas sustancias.

A sample of gas as a volume of 425 mL at 25°C at and 760 tour what volume with this gas sample have at STP

Answers

Answer:

[tex]\Rightarrow V_2 = 389mL[/tex]

Explanation:

To solve this question, we could use Charles' law since both the number of mole and pressure are constant

At STP pressure P = 760 tor and Temperature = 273K

V1 =425mL, T1 =298K and T2 =273K

and [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]

[tex]\Rightarrow V_2 =T_2\times\frac{V_1}{T_1}[/tex]

[tex]\Rightarrow V_2 =273\times\frac{425}{298}[/tex]

Therefore, [tex]\Rightarrow V_2 = 389mL[/tex]

What is the molarity of 5.60 mol of sodium carbonate in 1500 ml of solution?

Answers

Answer:

3.74 M

Explanation:

We know that molarity is moles divided by liters. The first thing to do here is convert your 1500 mL of solution to L. There's 1,000 mL in 1 L, so you need to divide 1500 by 1000:

1500 ÷ 1000 = 1.50

Now you can plug your values into the equation for molarity:

5.60 mol ÷ 1.50 L = 3.74 M

Balance the following reaction:
C2H6(g) + O2(g) → CO2(g) + H2O(g)

Answers

2 C2H6(g)+ 7 O2(g)-> 4 CO2(g) + 6 H2O(g)

To calculate the atoms of an element in a given molecule, we need to multiply stoichiometry by the number that is written on the foot of that element. Therefore, the balanced equation is

2C[tex]_2[/tex]H[tex]_6[/tex](g) + 7O[tex]_2[/tex](g) → 4CO[tex]_2[/tex](g) + 6H[tex]_2[/tex]O(g)

What is Balanced equation?

Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, displacement reaction.

C[tex]_2[/tex]H[tex]_6[/tex](g) + O[tex]_2[/tex](g) → CO[tex]_2[/tex](g) + H[tex]_2[/tex]O(g)

Multiply by 7 on reactant side and by 6 on product side to balance oxygen

C[tex]_2[/tex]H[tex]_6[/tex](g) + 7O[tex]_2[/tex](g) → CO[tex]_2[/tex](g) + 6H[tex]_2[/tex]O(g)

Now balance carbon and hydrogen

2C[tex]_2[/tex]H[tex]_6[/tex](g) + 7O[tex]_2[/tex](g) → 4CO[tex]_2[/tex](g) + 6H[tex]_2[/tex]O(g)

Therefore, the balanced equation is

Neptune is 30 AU (astronomical units) from the sun. How long, in light minutes, would it take for light from the sun to reach Neptune?

Answers

Answer:

250 light minutes takes

Explanation:

1 astonomical unit is equal to 1.50x10¹¹m

The light travels at the speed of 3.0x10⁸m/s. That means in 1 second, travels 3.0x10⁸m. To solve this question we must find the distance of neptune to the sun in meters. In this way we can find the seconds (And minutes) that need the light to travel from the sun to neptune:

Distance from Sun to neptune:

30AU * (1.50x10¹¹m / 1AU) = 4.5x10¹²m

Time transcurred:

4.5x10¹²m * (1s / 3.0x10⁸m) = 15000s

14. As the moles of salt added are increased, what
happens to the melting point of the water?

Answers

Salt lowers the freezing/melting point of water, so in both cases the idea is to take advantage of the lower melting point. Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius).

Salt increases the boiling point and decreases the melting point of water. That means if you add salt before heating some water on the stove, it will take longer to boil. Also, if you add salt to ice, it will melt faster.

What is the melting point?

Melting point is the temperature at which a given solid material changes from a solid state to a liquid, or melts.

Salt makes water boil at a higher temperature - water sticks to the salt ions, so they can't get out of the liquid as easily.

Salt makes water freeze at a lower temperature - it's probably harder for the water molecules to get organized into a solid-state with all the salt ions messing up its structure.

Hence, as the moles of salt are added melting point of the water increases.
