The following changes affect the value of the equilibrium constant for a gas-phase exothermic reaction:

Addition of a catalyst-  Increase equilibrium constant

Decrease in the temperature - Decrease equilibrium constant

Removal of a product- No effect on equilibrium constant

Decrease in the volume- Decrease equilibrium constant

Removal of a reactant- Decrease equilibrium constant

Define  exothermic process

An exothermic process in thermodynamics is a thermodynamic process or reaction that releases energy from the system to its surroundings, typically in the form of heat but occasionally in the form of light (such as a spark, flame, or flash), electricity (such as from a battery), or sound (such as the explosion produced by the burning of hydrogen).

The relationship between a reaction's products and reactants with regard to a certain unit is expressed by the equilibrium constant, K. The equilibrium constant is temperature-dependent and unaffected by the precise ratios of reactants to products, the presence of a catalyst, or the presence of inert substances. Additionally, it is unaffected by the volumes, pressures, and concentrations of the reactants and products.

Answer:

???

Explanation:

Sodium represents by the (Na).

Answer:

69.2 °C

Explanation:

To find the final temperature, you need to use the following equation:

Q = mcΔT

In this equation,

------> Q = heat (J)

------> m = mass (g)

------> c = specific heat capacity (J/g°C)

------> ΔT = T₂ - T₁ = change in temperature (°C)

To clarify, "T₁" represents the initial temperature and "T₂" represents the final temperature. You can plug the given values into the equation and simplify to find "T₂".

Q = 226 J                      c = 0.030 J/g°C

m = 192.4 g                   ΔT = T₂ - T₁ = T₂ - 30°C

Q = mcΔT                                                       <----- Given equation

Q = mc(T₂ - T₁)                                                <----- Rewrite ΔT

226 J = (192.4 g)(0.030 J/g°C)(T₂ - 30°C)     <----- Insert variables

226 J = 5.772(T₂ - 30°C)                                <----- Multiply 192.4 and 0.030

39.154 = T₂ - 30°C                                          <----- Divide both sides by 5.772

69.2 = T₂                                                        <----- Add 30 to both sides

The cultures of prehistoric humans are primarily known through the excavation of stone tools and other durable artifacts, such as the Oldowan and Acheulian tool traditions.

Stone tools and imperishable artifacts serve as key archaeological evidence for understanding prehistoric cultures. Through meticulous excavation and analysis, archaeologists have been able to piece together the lifestyles, technological advancements, and social behaviors of early human societies. The term "paleolithic" refers to the Old Stone Age, a time when humans relied on stone tools as their primary implements.

The Oldowan tool tradition is considered the earliest stone tool industry, dating back around 2.6 million years ago. It is characterized by simple tools, such as choppers and scrapers, which were crafted by flaking off pieces from larger stones. These tools were primarily used for basic activities like butchering and processing animal carcasses.

Later, the Acheulian tool tradition emerged around 1.76 million years ago, representing an advancement in stone tool technology. Acheulian tools, such as handaxes and cleavers, were more refined and standardized, showcasing an increased level of sophistication in tool-making techniques. These tools served a wide range of purposes, including hunting, woodworking, and shaping raw materials.

By studying the Oldowan and Acheulian tool traditions, researchers gain valuable insights into the cognitive abilities, cultural development, and technological progress of early humans. The examination of these artifacts provides evidence of their adaptability, problem-solving skills, and the gradual refinement of their tool-making techniques over time.

The heat required, to burn a hole 15 cm in diameter through the iron door is 34,370.050 kJ

Explanation:

The information given on the door are;

The thickness of the door, t = One-meter

The diameter of the hole to be burnt out, d = 15 cm = 0.15 m

The latent heat of fusion of iron, \(H_f\) = 247 kJ/kg

The density of iron, ρ = 7.874 g/cm³ = 7874 kg/m³

The volume of the iron to be melted off, V = π·d²/4 × t

∴ V = (π × 0.15²/4) × 1 ≈ 0.01767145867

The volume of the iron to be melted off, V ≈ 0.01767145867 m³

The mass of the iron to be melted off, m = ρ × V

∴ m = 7874 kg/m³ × 0.01767145867 m³ ≈ 139.145066 kg

The mass of the iron to be melted off, m ≈ 139.15 kg

The heat required, to melt the mass of iron at the melting point temperature and burn a hole 15 cm in diameter, ΔH, is given as follows;

ΔH = \(H_f\) × m

∴ ΔH = 139.15 kg × 247 kJ/kg = 34,370,050 J = 34,370.050 kJ

The heat required, to burn a hole 15 cm in diameter through the iron door ΔH = 34,370.050 kJ.

Small molecules make up water. There are three of them: two hydrogen atoms and one oxygen atom. Hydrogen bonding is a force that holds water molecules together. It is the cause of water's extraordinary abilities.

Our bodies require water for the following reasons:

1. It soothes joints:  In the spine's disks and in joints, cartilage contains about 80% water. Over time, dehydration can reduce the joints' ability to absorb damage, which can result in joint pain.

2.It produces mucous and saliva: Saliva helps in digestion and keeps the eyes, nose, and lips moist. Wear and tear are prevented in this way. Furthermore, drinking water maintains the mouth healthy. When substituted for sweetened beverages, it can also stop tooth decay.

3. It delivers oxygen throughout the body: Blood transports oxygen to various parts of the body and contains more than 90% water.

4. It protects delicate areas of the spinal cord and brain with padding: Brain anatomy and function can be impacted by dehydration. Additionally, it contributes to the synthesis of neurotransmitters and hormones. Long-term dehydration can cause issues with reasoning and thinking.

5. It controls the body's temperature: Perspiration is the result of the middle-layers of the skin's stored water being released when the body becomes hot. Evaporation causes the body to cool. in a sport. Some scientists claim that: Source of reality When the body doesn't have enough water, it can't handle heat stress as well, and it stores more heat. Lots of water consumption may help to reduce physical stress if heat stress occurs when exercising. Yet additional research is needed to fully understand these effects.

6. Water is necessary for the digestive system: The bowel need water to operate properly. Dehydration can lead to constipation, excessive stomach acid, and digestive problems. The likelihood of stomach ulcers and heartburn has increased as a result.

7. It keeps blood pressure stable: Lack of water can cause blood to become thicker. Enough water may reduce the likelihood of vasopressin release, which reduces the risk of high blood pressure, by keeping our cells and organs hydrated.

8. Water prevents kidney damage: The kidneys are in charge of body fluid. Water deficiency may result in kidney stones and other problems. Water is required by the bowel for proper operation. Dehydration can cause digestive problems such as constipation, excessive stomach acid, and more. As a result, it is now more probable to have heartburn and stomach ulcers.

The sum of 3(3)/(8) and 6(1)/(2) is 5(5)/(8), which is a mixed number representing 5 whole units and 5/8 of another unit.

To find the sum of mixed numbers, we need to add the whole numbers and the fractions separately. Add the whole numbers: 3 + 6 = 9

Add the fractions: For the fractions 3/(8) and 1/(2), we need to find a common denominator. The least common multiple of 8 and 2 is 8.

Converting 3/(8) to have a denominator of 8:

3/(8) = (3 x 1)/(8 x 1) = 3/(8)

Converting 1/(2) to have a denominator of 8:

1/(2) = (1 x 4)/(2 x 4) = 4/(8)

Now, we can add the fractions:

3/(8) + 4/(8) = (3 + 4)/(8) = 7/(8)

Combine the whole numbers and fractions:

The whole numbers sum was 9 and the fractions sum was 7/(8). We can write this as a mixed number by dividing the numerator (7) by the denominator (8). The quotient is 0 with a remainder of 7. Therefore, the mixed number is 0(7)/(8), which can be simplified to 7/(8).

Therefore, sum of 3(3)/(8) and 6(1)/(2) is 5(5)/(8).

In order to neutralise 15.0 mL of 1.00 M KOH, we therefore require 15.0 mL of 0.50 M Sulfuric acid.

Strong acid and strong base reactions produce a salt that is neither acidic nor basic in nature, or neutral. For instance, sodium chloride and water are produced when HCl (hydrochloric acid), a powerful acid, combines with NaOH, a powerful base.

First, let's calculate the number of moles of potassium hydroxide in 15.0 mL of 1.00 M solution:

moles of Potassium hydroxide = concentration × volume

moles of Potassium hydroxide = 1.00 M × 15.0 mL / 1000 mL per L = 0.015 mol

moles of Sulfuric acid = moles of KOH / 2 = 0.015 mol / 2 = 0.0075 mol

moles of Sulfuric acid = concentration × volume

0.0075 mol = 0.50 M × volume

volume = 0.0075 mol / 0.50 M = 0.015 L

volume in mL = 0.015 L × 1000 mL per L = 15.0 mL
