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>

Describe a method to calculate the average atomic mass of using only the atomic masses of
AnnZ [28]

Answer:

Average amu is 6.52556

Explanation:

Average the numbers

Add the two masses together.

6.01512+ 7.01600= 13.03112

Then divide by 2, we divide by 2 because that is how many #'s we are given.

13.03112/ 2= 6.52556

How many grams of glycerine, C3H8O3, are needed to make 100. mL of 2.60 M solution?
Masteriza [31]

Answer:

the mass of the glycerine needed in the given solution is  23.92 g

Explanation:

Given;

molarity of the solution (C₃H₈O₃), C = 2.60 M

Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M

The molarity of a solution is given as follows;

Molarity = \frac{amount \ of \ solute \ (moles)}{volume \ of \ solution \ (L)} \\\\amount \ of \ solute \ (moles) = Molarity  \ \times volume \ of \ solution \ (L)\\\\amount \ of \ solute \ (moles) = 2.6 \times 0.1 \\\\amount \ of \ solute \ (moles) = 0.26 \ mole

The molecular mass of the given solution;

molecular mass = (12 x 3) + (8 x 1) + (16 x 3)

molecular mass = 92 g/mol

The mass of the glycerine needed in the given solution is calculated as follows;

reacting mass = amount of solute (moles)   x   molecular mass (g/mol)

reacting mass = 0.26 x 92

reacting mass = 23.92 g

Therefore, the mass of the glycerine needed in the given solution is  23.92 g
