Given that E
bija089 [108]

The equilibrium constant of the reaction is 1.21 * 10^6 while the change in free energy is -34.7 kJ.

<h3>What is equilirium constant?</h3>

The equilibrium constant shows the extent of conversion of reactants to products.

Now we know from the Nernst equation that;

Ecell = E°cell - 0.0592/n logQ

E°cell = 0.52−0.16=0.36 V

Since Ecell = 0 V at equilibrium,

0 = 0.36 - 0.0592/1 log K

0.36  = 0.0592/1 log K

log K = 0.36/ 0.0592

K = antiog (0.36/ 0.0592)

K = 1.21 * 10^6

ΔG = -RT lnK

ΔG =-(8.314 * 298 * ln1.21 * 10^6)

ΔG =-34.7 kJ

A student melts 50.0 grams of ice using 16650 J of energy. What is the heat of fusion of ice?
Shkiper50 [21]
Heat fusion is the amount of energy required to convert one mole of ice into water, 16650J is per 50g so if we divide 16650 by 50 we find it per gram: 16650/50 = 333J/g or 0.33KJ/g

hope that helps :)

Chemistry help! Please zoom in to see better ​
sergeinik [125]

Answer:

82.04g

Explanation:

To solve this problem, you need to find the molar mass of HCl, which is the sum of the molar mass of H plus the molar mass of Cl. The molar mass of H is 1.008g/mol while the molar mass of Cl is 35.45g/mol. Thusly the molar mass of HCl is 36.458g/mol. You have 2.25 moles of HCl, so multiply the number of moles by the molar mass to get the mass in g. In this case it is 2.25mol * 36.458g/mol = 82.04g.

If I helped, a brainliest would be greatly appreciated!

How many moles of sodium atoms are contained in 3.5 moles of sodium sulfide
Aliun [14]

Answer:

7 moles

Explanation:

The molecular formula of sodium sulfide is Na_2S

One molecule of Sodium sulfide has 2 atoms of sodium and one atom of sulfur

1 mole of Sodium sulfide has  2 moles of sodium and one mole of sulfur

so 3.5 moles of sodium sulfide will have 2× 3.5 moles of sodium atoms

i.e 2×3.5= 7 moles of sodium atom
