Fe-54 = 5.845%

FrozenT [24]

Answer:

$\boxed {\boxed {\sf 55.76756 \ amu}}$

Explanation:

The average atomic mass is the sum of the product of the given masses and their abundances. We have to complete two steps for each isotope, then add all the products together.

Fe-54

Convert the percent abundance to a decimal by dividing by 100.

5.845/100= 0.05845

Multiply the abundance as a decimal by the mass number. This is the number after the element in the isotope symbol (54 amu).

0.005845 * 54=3.1563 amu

Fe-56

Convert the percent to a decimal.

91.754/100=0.91754

Multiply the decimal by the mass number (56 amu).

0.91754 * 56= 51.38224 amu

Fe-58

Convert the percent to a decimal.

2.119/100=0.02119

Multiply by the mass number (58 amu).

0.02119 * 58 = 1.22902 amu

Average Atomic Mass

Add all the products together to find the average atomic mass.

3.1563 amu + 51.38224 amu + 1.22902 amu =55.76756 amu

The average atomic mass given the percent abundance is 55.7656 atomic mass units.

Using the equation 40kJ+2SO3(g)-->2SO2(g) + O2(g), if pressure is added what way

Ad libitum [116K]

In an equation, 40kJ + 2SO₃ (g) -->2SO₂(g) + O₂(g), if pressure added, the equilibrium shifts to the left side of the reaction because it has fewer moles of gas.

<h3>What is Le Ch atelier's principle?</h3>

Le Ch atelier's principle states that if the pressure is added in a nay reaction, then the equilibrium will be shifted toward the side where there are fewer atoms.

In this case, there are fewer moles on the left side.

Thus, when pressure is added, the equilibrium shift to the left side due to Le Ch atelier's principle.

If you were asked to run Spartan calculations on the C2H3O2-/H3O ion pair, the trend in the resulting data points would appear s

Taya2010 [7]

Answer:

a. True

Explanation:

The data curve for OCI-/H3O appears to be similar to C2H3O2-/H3O because protons have not dissociated with conjugate base. This conjugate base is strong and hold proton in solution while acids try to dissociate it.
