Answer:

12.125 moles of Z

Explanation:

Hi! Here, since you only know the number of moles for one of the reactants, you will use the coefficients in the reaction to use the mole ratio to find your answer. Since the question states that there are 4.85 mol A and excess B, A is your limiting reactant. This means that once all of the A is used up in the reaction, you will have your maximum amount of Z left behind because there will only be B left and no A to make more Z.

The mole ratio of A:Z is 2:5, found from the coefficients in the chemical equation(2 moles of A for every 5 moles of Z).

So, start with the information that is given to you (4.85 mol A) and then use the mole ratio, like this:

4.85 mol A(\(\frac{5 mol Z}{2 mol A}\))

This way, the mol A will cancel out, leaving behind mol Z (always put the unit you are looking for on top).

Doing this leads to mol Z = 12.125 mol.

I hope this helps! Good luck with your finals!

As per the given 4.85 moles of A will produce 12.125 moles of Z, assuming excess B.

A chemical reaction is the transformation of one or more substances, known as reactants, into one or more different substances, known as products.

Chemical reactions involve the breaking and forming of chemical bonds between atoms and molecules, causing atoms to rearrange and the chemical and physical properties of the substances involved to change.

From the balanced chemical equation, we can see that 2 moles of A react with 3 moles of B to produce 5 moles of Z.

So the mole ratio of A to Z is 2:5.

Therefore, if 2 moles of A react to produce 5 moles of Z, then 4.85 moles of A will produce:

(4.85 mol A) x (5 mol Z / 2 mol A) = 12.125 mol Z

Thus, 4.85 moles of A will produce 12.125 moles of Z, assuming excess B.

0.0205 moles of water were lost if the amount of water lost was 0.369 grams. The given answer is in three significant figures with including zero before the decimal.

To find the number of moles of water lost, we need to know the molar mass of water (H2O).

Molar mass is the sum of the atomic masses of all the atoms present in a molecule.

Since the molecule of water contains two atoms of hydrogen and one atom of oxygen, the molar mass of water is given by the sum of the atomic masses of two hydrogen atoms and one oxygen atom, which is: 2(1.008 g/mol) + 1(15.999 g/mol) = 18.015 g/mol

Therefore, one mole of water has a mass of 18.015 g.

The number of moles of water lost can be calculated using the following formula: Number of moles = Mass of substance / Molar mass of substance

Substituting the given values, we get: Number of moles = 0.369 g / 18.015 g/mol = 0.0205 mol

Thus, 0.0205 moles of water were lost if the amount of water lost was 0.369 grams.

Explanation:

26.8L is the volume, in liters, of 1.20 mol of C\(_3\)H\(_8\) gas at STP. A measurement of three-dimensional space is volume.

A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, like the cubic metre or litre, or different imperial or US-standard units, including the gallon, quart and cubic inch. Volume and length (cubed) have a symbiotic relationship.

The volume of an envelope is typically thought of as its capacity, not as the amount of space it takes up. In other words, the volume is the quantity of fluid (liquid or gas) that the container may hold.

Explanation:

Given data:

density of lead = 11.342 g/cm³

Volume of lead = ?

Mass of lead = 200.0 g

Solution:

Formula:

Density = mass/volume

by putting values,

11.342 g/cm³ = 200.0 g/ v

v = 200.0 g/11.342 g/cm³

v = 17.6cm³

The density of lead is 11.342 g/cm³. 17.6cm³ would be the volume of a 200.0 g sample of this metal.

The density of a substance indicates how dense it is in a given area. Mass / unit volume is the definition of a material's density. In essence, density is a measurement of how closely stuff is packed. It is a particular physical characteristic of a specific thing. The Greek scientist Archimedes made the discovery of the density principle. If you are familiar with the formula and the relevant units, calculating density is simple. The letter D can also be used to signify density instead of the symbol.

D) drawing (4)                                  C) drawing (3)

Answer:

   B) drawing (2)

Explanation:

In Chemistry, the direction of dipole is shown from positive end to negative end.

The image that contains the options in the question asked has been attached.

We can see in image 2 that the oxygen atom was correctly designated as the negative end of the dipole while the carbon and hydrogen atoms were each designated as positive ends of the dipole in accordance with the magnitude of electronegativity difference between the two atoms. The net dipole moment is now taken in the direction shown in image 2. This is the correct answer.

Drawing 2 best accounts for the polarity of methanol, CH3OH. Therefore, the correct option is B.

A carbon atom (C) joins with three hydrogen atoms (H), a hydroxyl group (OH), and three other atoms to form methanol (CH3OH). An oxygen atom (O) is attached to a hydrogen atom to form a hydroxyl group. The three hydrogen atoms and hydroxyl groups are arranged in three dimensions, giving the molecular structure of methanol a tetrahedral form around the core carbon atom.

A polar covalent bond is formed between oxygen and hydrogen because the oxygen atom in the hydroxyl group is more electronegative than the carbon and hydrogen atoms. Due to the unequal sharing of electrons, oxygen has a partial negative charge (-) and hydrogen has a partial positive charge (+), resulting in this polarity.

So, the correct option is B.

Explanation:

Molarity (M) is defined as the number of moles of solute per liter of solution. To calculate the molarity of a solution, we can use the following formula:
M = moles of solute / volume of solution in liters

(a) For 20.0 g of ethanol (C2H5OH) in 415 mL of solution:
First, we need to calculate the number of moles of ethanol. The molar mass of ethanol is 46.07 g/mol.
Moles of ethanol = 20.0 g / 46.07 g/mol = 0.434 mol

Next, we need to convert the volume of solution from mL to L.
Volume of solution = 415 mL / 1000 mL/L = 0.415 L

Finally, we can calculate the molarity of the solution:
M = 0.434 mol / 0.415 L = 1.046 M

(b) For 24.0 g of sucrose (C12H22O11) in 67.0 mL of solution:
First, we need to calculate the number of moles of sucrose. The molar mass of sucrose is 342.30 g/mol.
Moles of sucrose = 24.0 g / 342.30 g/mol = 0.0701 mol

Next, we need to convert the volume of solution from mL to L.
Volume of solution = 67.0 mL / 1000 mL/L = 0.067 L

Finally, we can calculate the molarity of the solution:
M = 0.0701 mol / 0.067 L = 1.046 M

(c) For 5.40 g of sodium chloride (NaCl) in 88.0 mL of solution:
First, we need to calculate the number of moles of sodium chloride. The molar mass of sodium chloride is 58.44 g/mol.
Moles of sodium chloride = 5.40 g / 58.44 g/mol = 0.0924 mol

Next, we need to convert the volume of solution from mL to L.
Volume of solution = 88.0 mL / 1000 mL/L = 0.088 L

Finally, we can calculate the molarity of the solution:
M = 0.0924 mol / 0.088 L = 1.050 M

In conclusion, the molarity of each solution is:
(a) 1.046 M

Volume CO₂ produced  := 33.85 L

Given

120.0 grams of butane

55.0 liters of oxygen

Required

Carbon dioxide produced

Solution

Reaction(combustion of Butane) :

2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O.

mol of Butane (MW=58 g/mol) :

mol = mass : MW

mol = 120 : 58

mol = 2.069

At STP(1 atm, 273 K) , 1 mol gas=22.4 L, so for 55 L Oxygen :

mol O₂= 55 : 22.4 =2.455

Mol ratio of Butane and Oxygen = mol : reaction coefficient :

C₄H₁₀ : O₂ = 2.069/2 : 2.455/13 = 1.0345 : 0.189

Limiting reactant ⇒ O₂ (smaller ratio)

So mol CO₂ based on limiting reactant(O₂)

From equation, mol CO₂ : O₂ = 8 : 13, so mol CO₂ :

= 8/13 x mol O₂

= 8/13 x 2.455

= 1.511

Volume CO₂ at STP :

Explanation:

The time that is taken  is obtained as 5.21 × 10⁻⁵ s.

For the zero order reaction that we have, we can see that;

rate = 24.00 × 10²⁵ M/s

From the integrated rate law:

[C₂H₅OH]t = [C₂H₅OH]₀ - 24.00 × 10²⁵ M/s × t

We now obtain the half life as;

t(1/2) = [C₂H₅OH]₀ / 2 × k

t(1/2) = (1.25 × 10²² M) / 2 × (24.00 × 10²⁵ M/s) = 2.60 × 10⁻⁵ s

The time that is required is now obtained as;

[C₂H₅OH]t = [C₂H₅OH]₀ - 24.00 × 10²⁵ M/s × t

0 M = 1.25 × 10²² M - 24.00 × 10²⁵ M/s × t

t = 5.21 × 10⁻⁵ s

The rate constant for the decomposition of ethanol on an alumina surface is 24.00 × 10²⁵ M.

The integrated rate law is: [C₂H₅OH]t = [C₂H₅OH]₀ - 24.00 × 10²⁵ M/s × t

If the initial concentration of C₂H₅OH was 1.25 × 10²² M, the half-life is 2.60 × 10⁻⁵ s.

The time required for all the 1.25 × 10²² M C₂H₅OH to decompose is 5.21 × 10⁻⁵ s.
