KatRina [158]3 years ago

1.35 mole of K₂SO₄ contain 2.7 moles of cation.

Cations are positive ions. They are the ions of metallic elements.

To obtain the answer to the question, we'll begin by calculating the number of mole of cations in 1 mole of K₂SO₄.

K₂SO₄ (aq) —> 2K⁺ (aq) + SO₄²¯ (aq)

<h3>Cation => K⁺</h3>

From the balanced equation above,

1 mole of K₂SO₄ contains 2 moles of K⁺ (i.e cation).

Finally, we shall determine the number of mole of cation in 1.35 mole of K₂SO₄. This can be obtained as follow:

1 mole of K₂SO₄ contains 2 moles of K⁺ (i.e cation).

Therefore, 1.35 mole of K₂SO₄ will contain = 1.35 × 2 = 2.7 moles of K⁺ (i.e cation).

Hence, we can conclude that 1.35 mole of K₂SO₄ contain 2.7 moles of cation

What mass of carbon dioxide is produced upon the complete combustion of 26.5 L of propane (the approximate contents of one 5-gal
svet-max [94.6K]

Answer:

mCO2= 49.6932 kgCO2

Explanation:

Hello! Let's solve this!

First we propose the balanced equation C3H8 + 5O2 ---> 3CO2 + 4H2O

We see that each mole of C3H8 (propane) we get 3 moles of CO2

From the propane volume we can obtain the grams of propane used.

molpropane = 26.5L * (1000mL / 1L) * (0.621g / 1mL) * (1mol / 44g) = 374.01mol propane

mCO2 = 374.01molC3H8 * (3molCO2 / 1molC3H8) * (44gCO2 / 1molCO2) = 49369.32g * (1kg / 1000g) = 49.6932 kgCO2

mCO2= 49.6932 kgCO2

A gas absorbs 10J of heat and is simulataneously comptessed by a constant external pressure of 0.5atm from 4L to2L in volume.Wha
Ne4ueva [31]

Answer:

B. 111 J

Explanation:

The change in internal energy is the sum of the heat absorbed and the work done on the system:

ΔU = Q + W

At constant pressure, work is:

W = P ΔV

Given:

P = 0.5 atm = 50662.5 Pa

ΔV = 4 L − 2L = 2 L = 0.002 m³

Plugging in:

W = (50662.5 Pa) (0.002 m³)

W = 101.325 J

Therefore:

ΔU = 10 J + 101.325 J

ΔU = 111.325 J

Rounded to three significant figures, the change in internal energy is 111 J.
