Answers

Answer 1

[tex]\\ \tt\hookrightarrow 2C_4H_10+13O_2\longrightarrow 8CO_2+10H_2O[/tex]

13mol of O_2 reacts with 2mols of C_4H_10.7.5mol of O_2 reacts with 1mol of C_4H_10

No of moles:-

[tex]\\ \tt\hookrightarrow \dfrac{Given\:mass}{Molar\:mass}[/tex]

[tex]\\ \tt\hookrightarrow \dfrac{400}{58}[/tex]

[tex]\\ \tt\hookrightarrow 6.89mol[/tex]

Now

Moles of O_2

[tex]\\ \tt\hookrightarrow 7.5(6.89)=51.6mol[/tex]

Mass of O_2

[tex]\\ \tt\hookrightarrow 51.6(32)=1651.2g[/tex]

Answer 2

In the given question, 1.3kg is the mass of [tex]\rm O_2[/tex] that will react with 400g of           [tex]\rm C_4H_{10}[/tex] and 34.4 moles of [tex]\rm H_2O[/tex] are formed in the reaction.

Molar mass is the mass of one mole of a substance. It is expressed in grams per mole (g/mol).

a) To determine the mass of [tex]\rm O_2[/tex]that will react with 400 g of  [tex]\rm C_4H_{10}[/tex], we need to use stoichiometry to determine the mole ratio of  [tex]\rm C_4H_{10}[/tex] to  [tex]\rm O_2[/tex]in the balanced chemical equation.

[tex]\rm 2 C_4H_{10 }+ 13 O_2 \rightarrow 8 CO_2 + 10 H_2O[/tex]

From the equation, we can see that 2moles of  [tex]\rm C_4H_{10}[/tex] react with 13 moles of  [tex]\rm O_2[/tex]. Therefore, we can set up a proportion:

2 mol / 13 mol  [tex]\rm O_2[/tex]= 400 g   [tex]\rm C_4H_{10}[/tex] / x g  [tex]\rm O_2[/tex]

where x is the mass of  [tex]\rm O_2[/tex] that will react with 400 g of  [tex]\rm C_4H_{10}[/tex] .

Solving for x, we get:

x = (13 mol  [tex]\rm O_2[/tex]  [tex]\times[/tex] 400 g [tex]\rm C_4H_{10}[/tex] ) / (2 mol [tex]\rm C_4H_{10}[/tex] )

x = 1.3 kg  [tex]\rm O_2[/tex]

b) To determine the number of moles of water formed in part a), we need to use stoichiometry again to determine the mole ratio of  [tex]\rm C_4H_{10}[/tex] to  [tex]\rm H_2O[/tex] in the balanced chemical equation.

[tex]\rm 2 C_4H_{10 }+ 13 O_2 \rightarrow 8 CO_2 + 10 H_2O[/tex]

From the equation, we can see that 2moles of  [tex]\rm C_4H_{10}[/tex] react with 10 moles of  [tex]\rm H_2O[/tex] . Therefore, we can set up another proportion:

2 mol  [tex]\rm C_4H_{10}[/tex] / 10 mol  [tex]\rm H_2O[/tex] = 400 g  [tex]\rm C_4H_{10}[/tex] / x mol [tex]\rm H_2O[/tex]

where x is the number of moles of  [tex]\rm H_2O[/tex] formed.

First, we need to convert 400 g of  [tex]\rm C_4H_{10}[/tex] to moles:

400 g  [tex]\rm C_4H_{10}[/tex] [tex]\times[/tex] (1 mol  [tex]\rm C_4H_{10}[/tex] / 58.12 g  [tex]\rm C_4H_{10}[/tex] ) = 6.88 mol  [tex]\rm C_4H_{10}[/tex]

Now we can solve for x:

2 mol  [tex]\rm C_4H_{10}[/tex] / 10 mol  [tex]\rm H_2O[/tex] = 6.88 mol  [tex]\rm C_4H_{10}[/tex] / x mol  [tex]\rm H_2O[/tex]

x = (10 mol  [tex]\rm H_2O[/tex] [tex]\times[/tex]  6.88 mol  [tex]\rm C_4H_{10}[/tex]) / (2 mol  [tex]\rm C_4H_{10}[/tex] )

x = 34.4 mol  [tex]\rm H_2O[/tex]

Therefore, 1.3 kg of  [tex]\rm O_2[/tex] will react with 400 g of  [tex]\rm C_4H_{10}[/tex] .34.4 moles of water are formed when 400 g of  [tex]\rm C_4H_{10}[/tex] .

suppose you use a pitcher to to estimate 1.25 qt of water ( experimental volume) .

Answers

The percent error in the initial measurement would be 6.47%

Percent Error

Percent error in any measurement is mathematically given as:

                    absolute error/true measurement x 100%

In this case;

True measurement = 1.34 qt

Absolute Error = 1.34 - 1.25

                         = 0.09 qt

Percent error = 0.09/1.34 x 100%

what is the complete ionic equation?

what is the net ionic equation?

what are the spectator ions? ​​

Answers

Hello!

Complete ionic equations separate the equations into ion forms. Weak electrolytes and solids (precipitate) are exempt from this rule.

Net ionic equations are complete ionic equations but the ions that don't form as a precipitate are left out of the equation.

Anything cancelled out from the complete ionic equations are considered the spectator ions.

Looking at the equation, there are no weak electrolytes (you might have not covered this material yet), and the only precipitate in the solution is [tex]V(OH)_3[/tex].

1. What is the complete ionic equation?

Let's ionize the equation. Make sure all the atoms are correspondent with their coefficients. Don't forget their charges.

[tex]3Li^+(aq)+3OH^-(aq)+V^3^+(aq)+3Cl^-(aq)= 3Li^+(aq)+3Cl^-(aq)+V(OH)_3(s)[/tex]

Label every ion as (aq), and check the periodic table for their charges. Even without looking for V, we know that it is a 3+ charge since there are 3 chlorines attached to it.

2. What is the net ionic equation?

Get rid of all of the ions that don't do anything. Consider them lazy if they don't precipitate or form a solid. In this case, anything other than V and OH should be removed since they don't react. Think of it as cancelling out the ions that are still ions both sides.

[tex]V^3^+(aq)+3OH^-(aq)=V(OH)_3(s)[/tex]

3. What are the spectator ions?

Spectator ions are the cancelled out ions from the previous problem.

Cassidee walks 1-mile north and then turns and walks 2 miles west. Distance Displacement

Answers

Answer:

3 miles?

Explanation:

if you walk one mile North and then turn and walk another two miles you walk 3 miles and then turn around and walk back in the same direction you would end backup at the one-mile Mark he began. So three miles there two miles back

Cassidee traveled a distance of approximately 2.24 miles. Her displacement was approximately 2.24 miles westward.

Cassidee's motion forms a right triangle. Her first leg is 1 mile north, and her second leg is 2 miles west. Using the Pythagorean theorem:

Distance = √(1 mile)² + (2 miles)²

Distance = √1 + 4 = √5 ≈ 2.24 miles.

For displacement, we consider her initial and final positions. The horizontal component (westward) is 2 miles, and the vertical component (northward) is 1 mile. Using the Pythagorean theorem:

Displacement = √(Horizontal)² + (Vertical)²

Displacement = √2² + 1²

Displacement ≈ √4 + 1 = √5 ≈ 2.24 miles.

However, displacement needs a direction. Since she moves west, displacement is -2 miles west.

In summary, Cassidee traveled a distance of approximately 2.24 miles. Her displacement was approximately 2.24 miles westward.
