nekit [7.7K]
The system follow the Boyle's Law:

P_1\cdot V_1 = P_2\cdot V_2\ \to\ P_2 = \frac{P_1\cdot V_1}{V_2} = \frac{98\ kPa\cdot 77.4\ L}{60.0\ L} = \bf 126.4\ kPa

Consider the following reaction at 298 K: 2H2S(g)+SO2(g)→3S(s, rhombic)+2H2O(g),ΔG∘rxn=−102 kJ Is the reaction more or less spon
Taya2010 [7]

Answer:

The reaction is  more spontaneous than under standard conditions.

Explanation:

  • For ΔG°rxn, when it is:

negative: the reaction is spontaneous in the forward direction.

zero: the reaction is at equilibrium.

positive: the reaction is non-spontaneous in the forward direction and spontaneous in the reverse direction.

  • Since (ΔG°rxn = − 102 kJ) negative value:

<em>So, the reaction is  more spontaneous than under standard conditions. </em>

3)<br> How many atoms are in 14 moles of cadmium?
andre [41]

Answer:

8.4322\times10^{24} atoms atoms are in 14 moles of cadmium.

Explanation:

Cadmium is a white and  silvery  metal  that is found in the curst of the earth.During the  production process of metals such as lead, copper, zinc, cadmium is extracted

Cadmium is present in some foods and is emitted when fossil fuels like as coal and oil is used, smoking cigarettes. It is used in craft glazes, metal batteries, and coatings.

We know that 1 mole of  Cadmium (Cd contains) 6.023*1023 atoms, which is Avogadro's number.

So in 14 Grams of Cadmium, the number of atoms present is,

=>14×number atoms present in one cadmium atom

=>14\times 6.023\times10^{23}

=>8.4322\times10^{24} atoms
