25.0 grams of propane (C3H8) reacts with 25.0 grams of oxygen according to the following equation:
C3H8 (g) + 5O2 (g) →
3CO2 (g) + 4H2O (g)
A) Which is the limiting reagent?
B) What is the theoretical yield, in grams, of carbon dioxide?

Answers

Answer 1

Oxygen is the limiting reagent, as it produces less carbon dioxide and water compared to propane. And  the theoretical yield of carbon dioxide is  0.469 moles.

The reactant that produces less product will be the limiting reagent, as it will be completely consumed in the reaction while the other reactant will be left over.

To determine the limiting reagent, we need to calculate the amount of product that can be produced by both reactants and compare them.

First, we need to convert the given masses of propane and oxygen to moles using their molar masses.

Molar mass of propane (C3H8) = 44.1 g/mol

Molar mass of oxygen (O2) = 32.0 g/mol

Number of moles of propane = 25.0 g / 44.1 g/mol = 0.566 moles

Number of moles of oxygen = 25.0 g / 32.0 g/mol = 0.781 moles

Now we can use the stoichiometry of the balanced chemical equation to determine the amount of product that can be produced by both reactants. According to the balanced equation, 1 mole of propane reacts with 5 moles of oxygen to produce 3 moles of carbon dioxide and 4 moles of water.

Theoretical yield of carbon dioxide from propane = 0.566 moles C3H8 × (3 moles CO2 / 1 mole C3H8) = 1.70 moles CO2

Theoretical yield of carbon dioxide from oxygen = 0.781 moles O2 × (3 moles CO2 / 5 moles O2) = 0.469 moles CO2

Similarly, we can calculate the theoretical yield of water from both reactants:

Theoretical yield of water from propane = 0.566 moles C3H8 × (4 moles H2O / 1 mole C3H8) = 2.26 moles H2O

Theoretical yield of water from oxygen = 0.781 moles O2 × (4 moles H2O / 5 moles O2) = 0.625 moles H2O

From the above calculations, we can see that oxygen is the limiting reagent, as it produces less carbon dioxide and water compared to propane. Therefore, all 0.781 moles of oxygen will be consumed in the reaction, and only 0.469 moles of carbon dioxide and 0.625 moles of water can be produced. The remaining propane will be left over.

Sharon puts a large pot of water on the stove to boil pasta. Then she starts to make a tomato sauce. When the sauce is cooking, she looks at the pot of water and thinks the water level is much lower than it was. How does this diagram of part of the water cycle help Sharon explain what happened to the pasta water?

Answers

Answer:

1. A

2. C

Explanation:

For the first question, we know that the water transformed into a gas. This fact eliminates choices C and D, primarily because they describe the change as "gas to liquid" instead of liquid to gas.

What separates B from A is that B is saying the liquid changed to a gas in response to sunlight, which is completely false and impertinent to the prompt.

A is the correct answer.

for the second question, we know that condensation causes clouds -- and that neither evaporation nor water vapor would clear clouds to make more of them, which eliminates choices B and D. Going back to condensation, the accumulation of water vapor plays a big role in the formation of clouds. While evaporation does play a part in [it] as well, condensation is what caused the sudden appearance of clouds in the troposphere.

C is the correct answer.

The student should have multiplied the molar mass, which was not found, by the number of moles to get an answer of 925grams of Ca(OH)2.

Please find the correct step below

Explanation:

According to the question attached, the student was asked to find the mass in grams of a 12.5mol of Ca(OH)2.

Using the formula;

mole = mass ÷ molar mass

Molar mass of Ca(OH)2 = 40 + (16 + 1)2

= 40 + 17(2)

= 40 + 34

= 74g/mol

From the above formula;

Mass in grams = mole × molar mass

Mass (g) = 12.5 × 74

Mass (g) = 925grams of Ca(OH)2.

What are significant figures?

The number that is given as digits is established using significant figures. A significant depiction of numbers is carried by these digits. Frequently, significant numbers are employed in place of figures. By counting all of the values beginning with the first non-zero digit on the left, we may determine the number of significant digits. 13.56, for instance, has four significant digits.

The crucial or key digits that accurately represent the meaning of a certain number are known as the significant figures of that number. 7.864 contains four significant digits, for instance. These huge amounts give the accuracy of the numbers. Additionally, they are known as important digits.

Therefore, the correct options are B, C, and D.

Choose the aqueous solution below with the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable.

Answers

The question is incomplete, the complete question is;

Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. 0.100 m C6H12O6 0.100 m AlCl3 0.100 m NaCl 0.100 m MgCl2 They all have the same boiling point.

Answer:

AlCl3 0.100 m

Explanation:

Let us remember that the boiling point elevation is given by;

ΔTb = Kb m i

Where;

ΔTb = boiling point elevation

Kb = boiling point constant

m = molality of the solution

i = Van't Hoff factor

We can see from the question that all the solutions possess the same molality, ΔTb now depends on the value of the Van't Hoff factor which in turn depends on the number of particles in solution.

AlCl3 yields four particles in solution, hence ΔTb is highest for AlCl3 . The solution having the highest value of ΔTb also has the highest boiling point.
