What container appeared to have the least volume of liquid despite all three holding the same volume

Answer:

Explained below.

Explanation:

The difference between the two of them will be considered from their electrostatic potential maps.

First of all the major difference is that ammonia molecule(NH3) has a lone lone pair of electron on the N atom.

Due to the this lone pair of electron on the N - atom of ammonia, it's bond angle will be slightly lesser than that of ammonium ion.

Therefore, In the electrostatic potential map of NH3, the charge distribution will not be symmetrical for the fact that there is electron rich N atom and so the N atom will be more red than the 3 hydrogen atoms (H atoms).

Whereas, the electrostatic potential map of NH4+ (ammonium ion) will be symmetrical due to the even/symmetrical distribution of all the 4 hydrogen atoms surrounding the central Nitrogen atom.

Also, the Nitrogen atom here in ammonium ion will have a lower electron density than the Nitrogen atom that's present in ammonia molecule due to the bonding existing between the lone pair electron and the Hydrogen atom

Answer:

True

Explanation:

The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth's rotation. This statement is true.

Circulating air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere as the Earth rotates on its axis. The Coriolis effect refers to this deflection.

Because of the rotation of the Earth, we experience an apparent force known as the Coriolis force. The wind is deflected to the right in the northern hemisphere and to the left in the southern hemisphere as a result of this.

There is no curving of the object's path as measured relative to the Earth's surface because there is no turning of the Earth's surface  underneath a horizontally and freely moving object at the equator.

Thus, There is no Coriolis effect because the object's path is straight.

Explanation:

Let's go case by case:

A. No matter the volume, the concentration of Fe(NO₃)₃ (and thus of [Fe³⁺] as well) is 0.050 M.

B. We can calculate the moles of Fe₂(SO₄)₃:

Given that there are two Fe⁺³ moles per Fe₂(SO₄)₃ mol, in the solution we have 0.032 moles of Fe⁺³. With that information in mind we can calculate [Fe⁺³]:

C. Analog to case A., the molar concentration of Fe⁺³ is 0.040 M.

D. Similar to cases A and C., [Fe⁺³] = 0.010 M.

Thus none of the given options would have [Fe⁺³] = 0.020 M.

Answer:

312 g of O₂

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2KClO₃ —> 2KCl + 3O₂

From the balanced equation above,

2 mole of KClO₃ decomposed to 3 moles of O₂.

Next, we shall determine the number of mole of O₂ produced by the reaction of 6.5 moles of KClO₃. This can be obtained as follow:

From the balanced equation above,

2 mole of KClO₃ decomposed to 3 moles of O₂.

Therefore, 6.5 moles of KClO₃ will decompose to produce = (6.5 × 3)/2 = 9.75 moles of O₂.

Finally, we shall determine the mass of 9.75 moles of O₂. This can be obtained as follow:

Mole of O₂ = 9.75 moles

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ =?

Mole = mass / Molar mass

9.75 = Mass of O₂ / 32

Cross multiply

Mass of O₂ = 9.75 × 32

Mass of O₂ = 312 g

Thus, 312 g of O₂ were obtained from the reaction.

Answer:

3.1 × 10² g

Explanation:

Step 1: Write the balanced decomposition reaction

KClO₃ ⇒ KCl + 1.5 O₂

Step 2: Calculate the moles of O₂ formed from 6.5 moles of KClO₃

The molar ratio of KClO₃ to O₂ is 1:1.5.

6.5 mol KClO₃ × 1.5 mol O₂/1 mol KClO₃ = 9.8 mol O₂

Step 3: Calculate the mass corresponding to 9.8 moles of O₂

The molar mass of O₂ is 32.00 g/mol.

9.8 mol × 32.00 g/mol = 3.1 × 10² g

Answer: B. 4 moles Fe and 3 moles CO2

Explanation:

write a balanced chemical reaction

that is FeO3 + 3 CO → 2 Fe + 3CO2

2 moles of Fe2O3 reacted with 3 x2=6 moles of Co to form Fe and CO2 therefore CO was in excess and Fe2O3 was limiting reagent.

use the mole ratio to determine the moles of each product.

that is the mole ratio 0f Fe2O3 : Fe is 1:2 therefore the moles of Fe = 2x2=4 moles

the mole ratio of Fe2CO3 : CO2 is 1: 3 therefore the moles of Co2 = 2 x3 = 6 moles

If 2 moles of Fe2O3 react with 9 moles of CO, moles of each product is formed will be 6 moles.

A standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, etc, is referred to as mole.

According to the given scenario, the first one should create a chemical reaction that is balanced

FeO3 + 3 CO 2 Fe + 3CO2 is the formula.

Because 2 moles of Fe2O3 reacted with 3 x2=6 moles of Co to produce Fe and CO2, CO was in excess and Fe2O3 was the limiting reagent.

To calculate the moles of each product, use the mole ratio.

That is the Fe2O3 mole ratio: Because Fe is a 1:2 element, the mole of Fe is 2x2=4 moles.

Because the mole ratio of Fe2CO3 to CO2 is 1:3, the moles of Co2 are 2 x 3 = 6 moles.

Thus, If 2 moles of Fe2O3 react with 9 moles of CO, moles of each product is formed will be 6 moles.

C + O₂ → CO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

Being the molar mass of each compound:

By stoichiometry the following mass quantities participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

If 12 grams of C react, by stoichiometry 32 grams of O₂ react. But you have 40 grams of O₂. Since more mass of O₂ is available than is necessary to react with 12 grams of C, carbon C is the limiting reagent.

Then by stoichiometry of the reaction, you can see that 12 grams of C form 44 grams of CO₂.

44 grams of CO₂ will be formed.

Answer:

2.94 × 10²⁴ molecules

Explanation:

Step 1: Given data

Volume of acetone (V): 360 mL (360 cm³)

Density of acetone (ρ): 0.788 g/cm³

Step 2: Calculate the mass of acetone (m)

Density is equal to the mass of acetone divided its volume.

ρ = m/V

m = ρ × V

m = 0.788 g/cm³ × 360 cm³ = 284 g

Step 3: Calculate the moles corresponding to 284 g of acetone

The molar mass of acetone is 58.08 g/mol.

284 g × 1 mol/58.08 g = 4.89 mol

Step 4: Calculate the number of molecules in 4.89 moles of acetone

We will use Avogadro's number: there are 6.02 × 10²³ molecules of acetone in 1 mole of molecules of acetone.

4.89 mol × 6.02 × 10²³ molecules/1 mol = 2.94 × 10²⁴ molecules

Answer:

C3H6O

Explanation:

The percentage composition of the elements in the compound are given as follows:

62.1 % carbon = 62.1g of C

10.5 % hydrogen = 10.5g of H

27.6 % oxygen = 27.6g of O

Next, we convert each mass to mole by dividing by their molar/atomic mass

C = 62.1/12 = 5.175mol

H = 10.5/1 = 10.5mol

O = 27.6/16 = 1.725mol

Next, we divide each mole value by the smallest mole value (1.725)

C = 5.175mol ÷ 1.725 = 3

H = 10.5mol ÷ 1.725 = 6.086

O = 1.725mol ÷ 1.725 = 1

The empirical ratio approximately of C:H:O is 3:6:1, hence, the empirical formula is C3H6O

Answer:

The limiting reagent is O₂ if 5.2 grams of oxygen was present. The theoretical yield is 17.25g of Fe₂O₃

Explanation:

The reaction is:

4Fe + 3O₂  →  2Fe₂O₃

We convert the mass of each reactant to moles:

12.5 g . 1mol / 55.85g = 0.224 moles of Fe

5.2g . 1 mol/ 32g = 0.1625 moles of oxygen.

We analyse the stoichiometry.

4 moles of Fe react to 3 moles of O₂

Then 0.224 moles of Fe will react to (0.224 . 3)/4 = 0.1678 moles of O₂

I need 0.1678 moles of O₂ and I only have 0.1625. Oxygen is the limiting reactant.

Now we go to the products:

3 moles of O₂ can produce 2 moles of Iron (III) oxyde

Then, 0.1625 moles of O₂ may produce (0.1625 . 2)/3 = 0.108 moles of Fe₂O₃

We convert the moles to mass:

0.108 mol . 159.7g /1mol = 17.25 g
