What is formed by the interaction of lighting with oxygen ?

Looking at the solubility curve above for KClO3, at 30 degrees Celsius 37grams will dissolve to make a saturated solution.

Saturated and unsaturated solutions: what are they?

A saturated solution is one that has as much of the solute present as is capable of dissolving. A solution is said to be unsaturated if it doesn't contain all of the solute that can disperse in it.

A depiction of solubility (measured in g/100 g water) versus temperature (measured in °C) is known as a solubility curve. On the same graph, solubility curves for various substances are frequently depicted, allowing for easy comparisons. The curved line on the graph that depicts the connection between temperature and a substance's solubility at various temperatures is known as the solubility curve.

The energy needed to start a chemical reaction is called activation energy. The correct option is (3).

Activation energy refers to the minimum amount of energy required for a chemical reaction to begin or proceed. It acts as a barrier that needs to be overcome for reactant molecules to transform into products.

In order for a reaction to occur, the reactant molecules must have sufficient energy to surpass this energy barrier. Activation energy can be thought of as the "hurdle" that reactant molecules must jump over to initiate a chemical reaction.

Once the reaction is initiated and the activation energy is surpassed, the reactants undergo a series of bond-breaking and bond-forming processes, releasing or absorbing energy in the form of heat. Activation energy is a critical factor in determining the rate of a chemical reaction. Therefore, the correct option is (3).

Explanation:

Based on the given experimental record, the trend in the last column (time) is expected to decrease as the volume of sodium thiosulfate in water increases. This means that as the volume of sodium thiosulfate increases, the time taken for the cross to become invisible during the reaction decreases.

The rate of a chemical reaction is influenced by several factors, including the concentration of reactants. In this case, the volume of sodium thiosulfate represents the concentration of the reactant in the solution. When the volume of sodium thiosulfate is higher, the concentration of the reactant increases. According to the collision theory, a higher concentration of reactants leads to a greater frequency of successful collisions between particles, resulting in a faster reaction rate. In this experiment, the reaction between sulfuric acid and sodium thiosulfate forms a yellow precipitate, which obscures the visibility of the cross. As the concentration of sodium thiosulfate increases, more reactant particles are available, leading to a higher collision frequency and faster reaction rate. Consequently, the cross becomes invisible in a shorter time period. Therefore, the trend in the last column of the experimental record is expected to show a decrease in time as the volume of sodium thiosulfate increases.

Explanation:

These byproducts can accumulate within the closed jar, further contributing to the depletion of oxygen and ultimately causing the flame to go out.

When a jar is placed on top of a candle, it creates a closed environment within the jar. This closed environment leads to a depletion of oxygen, which is necessary for combustion to occur. As the candle burns, it consumes oxygen from the surrounding air to sustain the flame.

When the jar is placed over the candle, it limits the availability of fresh air and restricts the flow of oxygen into the jar. As the candle burns and consumes the available oxygen, it eventually uses up the oxygen trapped inside the jar. Without sufficient oxygen, the combustion process cannot continue, and the flame extinguishes.

Additionally, the combustion process produces carbon dioxide and water vapor as byproducts. These byproducts can accumulate within the closed jar, further contributing to the depletion of oxygen and ultimately causing the flame to go out.

The correct chemical formula for diphosphorous pentoxide is P₄O₁₀.

This compound is formed from the reaction of two molecules of phosphorus trioxide (P₂O₃). The prefix "di" indicates that there are two phosphorus atoms, and the suffix "-pentoxide" indicates that there are five oxygen atoms. The formula can also be written as (P₂O₅)₂, which represents the two P₂O₅ units that combine to form the molecule.

Diphosphorous pentoxide is a white, crystalline solid that is used as a dehydrating agent and in the production of phosphoric acid and other phosphorus compounds. It reacts violently with water, producing phosphoric acid and releasing heat, so it must be handled with care.

The major product expected for the reaction between bromine (Br₂) and sodium hydroxide (NaOH) is sodium bromide (NaBr), while the minor product is water (H₂O).

In this reaction, the bromine (Br₂) reacts with the sodium hydroxide (NaOH) to form sodium bromide (NaBr) as the major product. This occurs through a substitution reaction, where the bromine replaces the hydroxide group of sodium hydroxide, resulting in the formation of NaBr. The balanced chemical equation for this reaction is:

\(Br₂ + 2NaOH → 2NaBr + H₂O\)

Water (H₂O) is formed as a minor product during the reaction. It is produced from the combination of the hydroxide group from sodium hydroxide and one of the bromine atoms. However, NaBr is considered the major product because it is the primary product formed in higher quantities compared to water.

Explanation:

During the experiment, the heat absorbed by the water in joules is 2339.2 Joules.

The heat absorbed by the water is calculated using the formula of heat change as follows:

Q = m × c × ΔT

where;

We can calculate the mass of the water using its density:

mass of water = volume of water × density of water

mass of water = 175.0 mL × 1.00 g/mL

mass of water = 175.0 g

We can then calculate the change in temperature of the water:

ΔT = final temperature - initial temperature

ΔT = 28.7°C - 25.5°C

ΔT = 3.2°C

Now we can calculate the heat absorbed by the water:

Q = m × c × ΔT

Q = 175.0 g × 4.18 J/g·°C × 3.2°C

Q = 2339.2 J
