Answer:

139 mL

Explanation:

Given data:

Volume of solution required = ?

Molarity of solution = 0.222 M

Mass of salt = 9.57 g

Solution:

Number of moles of manganese iodide:

Number of moles = mass/molar mass

Number of moles = 9.57 g/ 308.75 g/mol

Number of moles = 0.031 mol

Volume required:

Molarity = number of moles of solute / volume in L

0.222 M = 0.031 mol / V

V = 0.031 mol / 0.222 mol/L

V = 0.139 L

Volume in mL:

0.139 L ×1000 mL / 1 L

139 mL

Given that 2S (s)+3O2 (g)→2SO3 (g)2SO2 (g)+O2 (g)→2SO3 (g) has an enthalpy change of −790.4 kJ has an enthalpy change of −198.2

abruzzese [7]

Answer:

The heat of formation of SO2 is -296.1 kJ

Explanation:

<u>Step 1:</u> Data given

2S (s)+3O2 (g)→2SO3 (g) ΔH = -790.4 kJ

2SO2 (g)+O2 (g)→2SO3 (g) ΔH = -198.2 kJ

<u>Step 2</u>: Calculate the heat of formation of SO2

2 S(s) + 3 O2(g) --> 2 SO3(g) ΔH = -790.4 kJ

S(s) + 3/2 O2(g) → SO3(g) ΔH = -395.2 kJ

2SO2 (g)+O2 (g)→2SO3 (g) ΔH = -198.2 kJ

SO3(g) → SO2(g) + 1/2 O2(g) ΔH = 99.1 kJ

----------------------------------------------------------------

S(s) + 3/2 O2(g) → SO3(g) ΔH = -395.2 kJ

SO3(g) → SO2(g) + 1/2 O2(g) ΔH = 99.1 kJ

-------------------------------------------------------------------

S (s)+O2 (g)→SO2 (g)

ΔHrxn = (-790.4 /2) kJ + (198.2/2) kJ

ΔHrxn = -395.2 kJ + 99.1 kJ = 296.1 kJ

The heat of formation of SO2 is -296.1 kJ

How many carbon atoms are there in a diamond (pure carbon) with a mass of 55 mg ?

kari74 [83]

1 mol of Carbon = 12 grams.
x mol of Carbon = 55 grams

12*x = 1 * 55
x = 55/12
x = 4.583333 mols of carbon

1 mol of anything is 6.02 * 10^23 atoms
4.58333333 mol = x

1/4.5833333 = 6.02 * 10^23/x
x = 4.58333* 6.02*10^23
x = 2.7591 * 10^23 Carbon atoms

a flask was filled with SO2 at a partial pressure of 0.409 atm and O2 at a partial pressure of 0.601 atm. The following gas-phas

jarptica [38.1K]

Answer:

The equilibrium partial pressure of O2 is 0.545 atm

Explanation:

Step 1: Data given

Partial pressure of SO2 = 0.409 atm

Partial pressure of O2 = 0.601 atm

At equilibrium, the partial pressure of SO2 was 0.297 atm.

Step 2: The balanced equation

2SO2 + O2 ⇆ 2SO3

Step 3: The initial pressure

pSO2 = 0.409 atm

pO2 = 0.601 atm

pSO3 = 0 atm

Step 4: Calculate the pressure at the equilibrium

pSO2 = 0.409 - 2X atm

pO2 = 0.601 - X atm

pSO3 = 2X

pSO2 = 0.409 - 2X atm = 0.297

X = 0.056 atm

pO2 = 0.601 - 0.056 = 0.545 atm

pSO3 = 2*0.056 = 0.112 atm

Step 5: Calculate Kp

Kp = (pSO3)²/((pO2)*(pSO2)²)

Kp = (0.112²) / (0.545 * 0.297²)

Kp = 0.261

The equilibrium partial pressure of O2 is 0.545 atm

Create a comic strip that follows the journey of energy from the sun as it travels through the humpback whale

Arisa [49]

The path of energy flow from the sun to the humpback whale is as follows:

Sun---> Plankton ---> Small fishes ---> Humpback whale.

<h3>What is energy?</h3>

Energy is the ability to do work.

The primary source of energy on the earth is the sun.

The energy from the sun is used by producers to produce food on which other organisms depend on.

The energy from the sun gets to the humpback whale through producers such as plankton.

The path of energy flow from the sun to the humpback whale is as follows:

Sun---> Plankton ---> Small fishes ---> Humpback whale.
