9. Using the balanced equation from Question #8, how many grams of lead will be produced if 2.54 grams of PbS is burned with 1.88 g of O2? Express your answer to the correct number of significant figures and you must show all work in the form of dimensional analysis as shown in Lesson 4. (Hint: be sure to work the problem with both PbS and O2).

Answers

Answer: 2.24 grams of Pb

Explanation:

Step 1

Balanced chemical reaction;

2PbS + 3O2 → 2Pb + 2SO3

Step 2

Moles of both PbS and O2

Moles = mass / molar mass

Moles of PbS = 2.54 g / 239.3 g/mol = 0.0108 moles

Moles of O2 = 1.88 / 32 g/mol = 0.0588 moles

Step 3

Finding the limiting reactant.

Limiting reactant, is that reactant which is completely used in the reaction;

If we assume that PbS is the limiting reactant;

We have 0.0588 moles of O2. This needs ( 0.0588 * 2) / 3 = 0.0392 moles of PbS to fully react. But we have only 0.0108 moles of PbS available. That means that the PbS will be completely consumed hence the limiting reactant

If we assume O2 is the limiting reactant;

We have 0.0108 moles of PbS. That needs ( 0.0108 * 3) / 2 = 0.0162 moles of O2. But we have 0.0588 moles of O2 which is in excess further confirming that PbS is the limiting reactant since it will be depleted in the reaction.

Step 4

Moles of lead

For this step we apply the mole ratios with the limiting reactant;

Mole ratio of PbS : Pb = 2 : 2 = 1 : 1

Therefore;

Moles of Pb = (0.0108 moles  * 1 ) 1

Moles of Pb =0.0108 moles

Step 5

Mass of Pb

Mass = moles * molar mass

Mass of Pb =0.0108 moles * 207.2 g/mol

Mass of Pb = 2.24 grams

Suppose that a car's starter motor draws 221 A of current for 6.20 s to start the car. What mass of Pb is oxidized in the lead–acid battery to supply this much electricity?

1.47 grams
Actually, I figured it out., here is the answer in case anyone is wondering:
It has two electrons in the process and Q is 1370.2 (Q= I*T= 221*6.2=1370.2) this gets to 1370.2/192736 (the number on the denominator is due to that fact that there are two electrons involved) That equals 0.007 Mols, and then using the grams per mol from the periodic table for lead, we get that value is equal to 1.47 grams.

Answers

The lead acid battery produces energy by oxidation of lead. The amount of lead oxidized in this case is 1.47 g.

What is lead acid battery?

The lead acid battery is the common accumulator that we have in use. It is made up of a cell that contains lead electrodes in an acid.

The oxidation of lead occurs according to thr equation;

Pb(s) ----> Pb^2+(aq) + 2e

If 207 g of Pb is oxidized by 2(96500)C

x g of lead is oxidized by (221 * 6.20) C

x = 207 g * (221 * 6.20) C/2(96500)C

x = 1.47 g

From the reaction: B2H6 + O2 HBO2 + H2O a. What mass of O2 will be needed to burn 36.1 g of B2H6? b. How many moles of water are produced from 19.2 g of B2H6?

Answers

A. The mass of O₂ needed to burn 36.1 g of B₂H₆ is 123.77 g

B. The number of mole of water, H₂O produced from 19.2 g of B₂H₆ is 1.372 mole

Balanced equation

B₂H₆ + 3O₂ —> 2HBO₂ + 2H₂O

Molar mass of B₂H₆ = (2×11) + (1×6) = 28 g/mol

Mass of B₂H₆ from the balanced equation = 1 × 28 = 28 g

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 3 × 32 = 96 g

SUMMARY

From the balanced equation above,

28 g of B₂H₆ required 96 g of O₂

A. How to determine the mass of O₂ needed

From the balanced equation above,

28 g of B₂H₆ required 96 g of O₂

Therefore

36.1 g of B₂H₆ will require = (36.1 × 96) / 28 = 123.77 g of O₂

Thus, 123.77 g of O₂ is required for the reaction

B. How to determine the mole of water produced

We'll begin by calculating the number of mole of in 19.2 g of B₂H₆. This can be obtained as follow:

Mass of B₂H₆ = 19.2 g Molar mass of B₂H₆ = 28 g/mol Mole of B₂H₆ =?

Mole = mass / molar mass

Mole of B₂H₆ = 19.2 / 28

Mole of B₂H₆ = 0.686 mole

Finally, we shall determine the number of mole of water produced. This is illustrated below:

Balanced equation

B₂H₆ + 3O₂ —> 2HBO₂ + 2H₂O

From the balanced equation above

1 mole of B₂H₆ reacted to produce 2 moles of H₂O

Therefore, H₂O

0.686 mole of B₂H₆ will react to produce = 0.686 × 2 = 1.372 mole of H₂O

Thus, 1.372 mole of H₂O was obtained from the reaction

what is Newton's second law of motion ​

Answers

Answer:

Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

Explanation:

Answer:

F= m x a

force = mass x acceleration

Explanation:

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased.

Vascular plants, also known as tracheophytes, are highly advanced plant creatures with leaves, stems, and roots, as well as a vascular system made up of conducting vessels. Ferns are herbaceous, pteridophytic vascular plants that do not produce flowers or seeds. Gymnosperms are vascular plants that produce seeds but do not produce blooms. Because the seeds aren't covered or protected by an ovary, they can be seen on the plant's leaves or other components. Angiosperms are flowering plants containing seeds that develop inside the ovary, which develops and produces fruit.
