Pressure and volume are inversely proportional according to Boyle's law. The graph should be linear with a negative slope.

P 4 + 5O 2 P 4 O 10 , 1.5 moles of product was made in 30 seconds. What is the rate of reaction? 0.011 g/min 210 g/min 380 g/min

Airida [17]

Answer: 850.0 g/min.

Explanation:

The rate of the reaction = (ΔC/Δt) where,

ΔC is the change in concentration of reactants or products.

Δt is the change in time of the reaction proceeding.

The rate is needed to be calculated in (g/min).

We need to calculate the amount of the product in (g) via using the relation (n = mass / molar mass).

mass (g) = n x molar mass,

n = 1.5 moles and molar mass of P₄O₁₀ = 283.88 g/mol.

m = 1.5 x 283.88 = 425.82 g.

ΔC = 425.82 g and Δt = 30 s / 60 = 0.5 min.

The rate of the reaction = ΔC / Δt = (425.82 g / 0.5 min) = 851.64 g/min.

can be approximated to 850.0 g/min.

I NEED HELP PLEASE, THANKS! :)

Answer:

$\large \boxed{\text{2.20 g Pb}}$

Explanation:

They gave us the masses of two reactants and asked us to determine the mass of the product.

This looks like a limiting reactant problem.

1. Assemble the information

We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.

Mᵣ: 239.27 32.00 207.2

2PbS + 3O₂ ⟶ 2Pb + 2SO₃

m/g: 2.54 1.88

2. Calculate the moles of each reactant

$\text{Moles of PbS} = \text{2.54 g PbS } \times \dfrac{\text{1 mol PbS}}{\text{239.27 g PbS}} = \text{0.010 62 mol PbS}\\\\\text{Moles of O}_{2} = \text{1.88 g O}_{2} \times \dfrac{\text{1 mol O}_{2}}{\text{32.00 g O}_{2}} = \text{0.058 75 mol O}_{2}$

3. Calculate the moles of Pb from each reactant

$\textbf{From PbS:}\\\text{Moles of Pb} = \text{0.010 62 mol PbS} \times \dfrac{\text{2 mol Pb}}{\text{2 mol PbS}} = \text{0.010 62 mol Pb}\\\\\textbf{From O}_{2}:\\\text{Moles of Pb} =\text{0.058 75 mol O}_{2} \times \dfrac{\text{2 mol Pb}}{\text{3 mol O}_{2}}= \text{0.039 17 mol Pb}\\\\\text{PbS is the $\textbf{limiting reactant}$ because it gives fewer moles of Pb}$

4. Calculate the mass of Pb

$\text{ Mass of Pb} = \text{0.010 62 mol Pb} \times \dfrac{\text{207.2 g Pb}}{\text{1 mol Pb}} = \textbf{2.20 g Pb}\\\\\text{The reaction produces $\large \boxed{\textbf{2.20 g Pb}}$}$

Describe the difference between intensive and extensive propoerties. Which of the following propoerties are intensive: (a) mass;

STatiana [176]

Answer:

The properties that do not vary with the variation in the quantity of the material are called as intensive property.

While the extensive properties are those which vary with the variation in the quantity of the material.

Intensive properties:

Mass and volume

Extensive properties:

Density and melting point

Explanation:

The properties that do not vary with the variation in the quantity of the material are called as intensive property.

While the extensive properties are those which vary with the variation in the quantity of the material.

Intensive properties:

Mass and volume, as with increase in quantity of the material mass and volume increases.

Extensive properties:

Density and melting point, as they remain constant for a object or material
