Answer:

Can be produced 288mL of SO₂

Explanation:

Based in the reaction:

P₄S₃ + 8O₂ → P₄O₁₀ + 3SO₂

<em>Where 1 mole of tetraphosphorus trisulfide reacts producing 3 moles of sulfur dioxide gas.</em>

0.869g of tetraphosphorus trisulfide (Molar mass of P₄S₃: 220.09g/mol) are:

0.869g P₄S₃ ₓ (1mol / 220.09g) = 3.948x10⁻³ moles of P₄S₃

As 3 moles of SO₂ are produced per mole of P₄S₃:

3.948x10⁻³ moles of P₄S₃ ₓ (3 moles SO₂ / 1 mole P₄S₃) = 0.0118 moles SO₂

Using PV = nRT

V = nRT / P

<em>Where n are 0.0118 moles, R gas constant (0.082atmL/molK), T absolute temperature (21.0°C + 273.15K = 294.15K), and P pressure (751torr / 760 = 0.988atm).</em>

Replacing:

V = 0.0118molₓ0.082atmL/molKₓ294.15K / 0.988atm

V = 0.288L = 288mL

Anyone know why its important for membranes to be selectivity permeable?
lorasvet [3.4K]
The term, selectively permeable, refers to the fact that the membrane allows some substances or molecules to enter the cells, and others to be prevented from entering. It also allows substances to leave the cell. All of this is dependent on the size of the molecule and the concentrations on either side of the membrane.

Selectively permeable membranes are important in maintaining homeostasis, fluid and electrolyte balance, and cellular health. Cells need to receive glucose and other nutrients in order to carry on normal cellular processes, and eliminate waste products of metabolism to avoid the accumulation of cellular toxins which can disrupt cellular processes and lead to cellular death.

Which of the following describes an exothermic reaction?
sattari [20]

Answer:

The answer to your question is: second option.

Explanation:

An exothermic reaction is a reaction that releases energy to the environment.

Thermal energy is absorbed by the system. This sentence is describing an endothermic reaction.

Thermal energy is absorbed by the surroundings. This sentence is describing an exothermic reaction.

Thermal energy is not transferred.  This sentence is describing an isolated system.

The initial and final temperatures of the system remains the same. This option is incorrect is not describing an exothermic reaction.
