Answer:

1) C9H16 + 13O2 → 9CO2 + 8H2O

2) C10H20 + 15O2 → 10CO2 + 10H2O

3) C8H20 + 13O2 → 8CO2 + 10H2O

Explanation:

Complete combustion is when a substance burns and reacts with oxygen fully to produce carbon dioxide and water.

1) With the first molecule C9H16, let's write the equation:

C9H16 + O2 → CO2 + H2O

This equation is not balanced. First, let's balance the carbons in the reactants (left side) and products (right side):

We have 9 carbons on the left and 1 carbon on the right, so let's add a coefficient of 9 in front of the CO2 to make it balanced:

C9H16 + O2 → 9CO2 + H2O

Now that the number of carbon is balanced on both sides, let's balance the number of hydrogen:

The equation we have now:

C9H16 + O2 → 9CO2 + H2O

We have 16 hydrogens on the left and 2 hydrogens on the right, so let's add a coefficient of 8 in front of H20 because 8 × 2 = 16:

C9H16 + O2 → 9CO2 + 8H2O

All we need to do now is balance the oxygen:

We have 2 oxygens on the left and 26 oxygens on the right ( because in 9CO2 there are 9×2=18 oxygens and in 8H2O there are 8×1=8 oxygens, so 18+8=26)

Current equation:

C9H16 + O2 → 9CO2 + 8H2O (unbalanced)

To make the number of oxygens equal, add a coefficient of 13 in front of O2 because 13×2=26, so both sides are equal:

This is the final equation:

C9H16 + 13O2 → 9CO2 + 8H2O

2) Doing the same thing to C10H20:

C10H20 + O2 → CO2 + H2O

The number of carbons is not the same on both sides, so add a coefficient of 10 to CO2 so that there are 10 carbons on each side:

C10H20 + O2 → 10CO2 + H2O

Now let's balance the number of hydrogens. There are 20 hydrogens on the left and 2 hydrogens on the right, so add a coefficient of 10 in front of H2O because 10×2=20, so both sides have 20 hydrogens:

C10H20 + O2 → 10CO2 + 10H2O

Lastly balancing the number of oxygens. There are 2 oxygens on the left and 30 oxygens on the right (because in 10CO2 there are 10×2=20 oxygens and in 10H2O there are 10×1=10 oxygens, so 20+10=30)

Add a coefficient of 15 in front of O2 because 15×2=30, making both sides of oxygen equal to 30

Final equation:

C10H20 + 15O2 → 10CO2 + 10H2O

3) Now for C8H20:

C8H20 + O2 → CO2 + H2O (unbalanced)

Let's balance the number of carbons by adding a coefficient of 8 in front of CO2 to make both sides of carbon equal to 8:

C8H20 + O2 → 8CO2 + H2O

There are 20 hydrogens on the left and 2 hydrogens on the right, so add a coefficient of 10 to H2O because 10×2=20, so both sides of hydrogen are equal to 20:

C8H20 + O2 → 8CO2 + 10H2O

Lastly, balancing the oxygens. There are 2 oxygens on the left and 26 oxygens on the right (because in 8CO2 there are 8×2=16 oxygens and in 10H2O there are 10×1=10 oxygens, so 16+10=26)

Add a coefficient of 13 in front of O2 because 13×2=26, so there will be 26 oxygens on both sides.

Final equation:

C8H20 + 13O2 → 8CO2 + 10H2O

According to the information of the graph we can infer that if the water were cooled to 5°C the reaction time would be close to 30 seconds.

To establish what would the reaction time be if the water were cooled to 5°C we have to analyze the information of the graph specially the trend. In this case, we have to take into account where are located the point that relate time and temperature.

In this case, the trend is more time with less temperature. So if the water were colled to 5°C, the time would be close to 30 seconds.

In catalysis and base catalysis, a chemical reaction is catalysed by an acid or a base.

Covalent catalysis involves the formation of a covalent bond.

Metal ions contribute to the catalytic process through their ability to attract or donate electrons.

An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.

In catalysis and base catalysis, a chemical reaction is catalysed by an acid or a base. by Bronsted - Lowry acid-base theory, the acid is the proton ( hydrogen ion, H+) donor and a base is the proton accentor typical reaction catalyzed by proton transfer are esterifications and aldol reactions .

Covalent catalysis involves the formation of a covalent bond between the enzyme and at least one of the substrates involved in the reaction. Often times this involves nucleophilic catalysis which is a subclass of covalent catalysis.

Metal ions are essential for the catalytic action of some enzymes. Metal ions contribute to the catalytic process through their ability to attract or donate electrons.

1. The empirical formula of the compound is NaOCl.

2. The compound with an empirical formula of CH has a molecular formula of \(C_ 6H_6.\) Option C

1. To determine the empirical formula of the compound, we need to find the simplest ratio of the elements present in the compound. We can assume a 100 g sample of the compound to make calculations easier.

Given that the compound is 25.42% Na, 35.40% O, and 39.18% Cl by mass, we can calculate the number of moles of each element in the 100 g sample:

Na: (25.42 g / 22.99 g/mol) = 1.106 mol

O: (35.40 g / 16.00 g/mol) = 2.213 mol

Cl: (39.18 g / 35.45 g/mol) = 1.104 mol

To find the simplest whole-number ratio, we divide the number of moles of each element by the smallest number of moles:

Na: 1.106 mol / 1.104 mol ≈ 1

O: 2.213 mol / 1.104 mol ≈ 2

Cl: 1.104 mol / 1.104 mol = 1

The empirical formula of the compound is NaOCl.

2. The empirical formula of CH implies a molar mass of approximately 13.01 g/mol (12.01 g/mol for carbon + 1.01 g/mol for hydrogen).

Given that the compound has a molar mass of 78.11 g/mol, we can find the ratio between the molar mass of the compound and the molar mass of the empirical formula:

78.11 g/mol / 13.01 g/mol ≈ 6

This means that the molecular formula of the compound is a multiple of the empirical formula. Therefore, the compound's molecular formula can be determined by multiplying the empirical formula by 6:\(C_ 6H_6.\). Option C

This equation defines system as a thermodynamic state variable, which indicates that its value is totally determined by the present state of the system and is not at all affected by how the system arrived at that state.

Explanation :

Entropy is a comprehensive quality in the sense that its intensity is proportional to the quantity of material present in the system.

This entropy production results from processes occurring within the system, such as chemical reactions, internal matter diffusion, internal heat transfer, and frictional effects occurring within the system as a result of mechanical work being transferred to or from the system.

An example of the latter would be viscosity.

a. Comparing N2O (at 0 K) and He (at 10 K), He has the greater value of S (entropy) because it is at a higher temperature (10 K) than N2O (0 K). Entropy increases with temperature.

b. Comparing N2O(g) (at 1 atm, 25°C) and He(g) (at 1 atm, 25°C), N2O has the greater value of S because it is a more complex molecule with more possible microstates than the simpler helium atom. Entropy increases with complexity.

c. Comparing H2O(s) (at 0°C) and H2O(l) (at 0°C), H2O(l) has the greater value of S because the liquid phase has more freedom of movement and more possible microstates than the solid phase. Entropy increases with disorder.

The nucleus more easily, increasing the probability of causing fission many nuclei like U234, U236, and U238 undergo fission only by fast neutrons.

Fission can be caused by slow as well as fast neutrons. It is the energy of the neutron which determines its effectiveness in causing fission. Fast neutrons are more effective in causing fission. Hence, many nuclei like U234, U236, and U238 undergo fission only by fast neutrons.

Fission is a nuclear reaction process in which the nucleus of an atom is split into two smaller nuclei with the release of a large amount of energy and two or three neutrons. Uranium-235 (U-235) and Plutonium-239 (Pu-239) are the most commonly used fissile materials, but other materials like U-234, U-236, and U-238 can also undergo fission. When a neutron is absorbed by the nucleus of a fissile material like U-235 or Pu-239, it becomes unstable and splits into two smaller nuclei with the release of a large amount of energy.

The fission process also releases two or three neutrons, which can cause further fission of other nuclei, leading to a chain reaction. The chain reaction can be controlled by using a neutron moderator, which slows down the fast neutrons, making them more effective in causing fission. The efficiency of the fission reaction depends on the energy of the neutron.

Fast neutrons are more effective in causing fission than slow neutrons, which have less energy. This is because fast neutrons can penetrate the nucleus more easily, increasing the probability of causing fission. Hence, many nuclei like U234, U236, and U238 undergo fission only by fast neutrons.

Answer: All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample). Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties. For example, pure copper is always a reddish-brown solid (a physical property) and always dissolves in dilute nitric acid to produce a blue solution and a brown gas (a chemical property).

Physical properties can be extensive or intensive. Extensive properties vary with the amount of the substance and include mass, weight, and volume. Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature. For example, elemental sulfur is a yellow crystalline solid that does not conduct electricity and has a melting point of 115.2 °C, no matter what amount is examined (Figure 1.3.1). Scientists commonly measure intensive properties to determine a substance’s identity, whereas extensive properties convey information about the amount of the substance in a sample.

The number of hamburgers sold on Wednesday is 275.

Let's assume the number of hamburgers sold is x.

According to the given information, the number of cheeseburgers sold is 70 more than the number of hamburgers. So, the number of cheeseburgers sold can be expressed as x + 70.

The total number of hamburgers and cheeseburgers sold is given as 620, so we can set up the following equation:

x + (x + 70) = 620

Combining like terms, we get:

2x + 70 = 620

Subtracting 70 from both sides of the equation:

2x = 550

Dividing both sides by 2:

x = 275
