Answer:

It’s caused by a disturbance.

It carries energy.

Explanation:

A wave is a disturbance that transmits energy from one point to another. It does no necessarily carry the particles or matter of the medium.

Waves usually carries energy. It is this energy they use in creating disturbances.

Not all waves carries matter; a good example is electromagnetic waves. Also, electromagnetic waves do not require a medium for propagation.

Most enzymes do not work if the temperature is raised too much because enzymes are proteins and their function depends on their shape.

Enzymes have an optimal temperature range at which they function most efficiently. If the temperature is too high, the enzymes can become denatured, which means they lose their shape and function. Additionally, at higher temperatures, the substrate molecules are moving too quickly for the enzymes to bind to them effectively, leading to a decrease in enzyme activity. Therefore, it is essential to maintain a suitable temperature for enzymes to function correctly.

Enzymes are biological molecules that serve as catalysts in a variety of biochemical processes that take place inside of living things. Typically, proteins are responsible for accelerating chemical processes by reducing the activation energy necessary for the reaction to take place. Enzymes attach to particular substrates and transform them into products while staying unaltered. Due to the extreme specificity of each enzyme for a certain substrate or class of substrates, metabolic pathways can be precisely controlled. Numerous physiological processes, such as digestion, cellular respiration, and DNA replication, depend heavily on enzymes. Many biochemical processes would move too slowly without enzymes to support life.

Explanation:

The amount of heat released from the combustion of 55 grams of ethanol with excess oxygen would be -1626.573 kJ.

The reaction for the combustion of ethanol is:

C₂H5OH + 3O₂ → 2CO₂ + 3H₂O (AH° = -1366.7 kJ)

55 g ethanol x (1 mol / 46.07 g) = 1.19 mol ethanol

According to the balanced chemical equation, 1 mol of ethanol releases -1366.7 kJ of heat:

1 mol ethanol x (-1366.7 kJ / mol) = -1366.7 kJ

So, for 1.19 mol of ethanol combusted, the heat released will be:

1.19 mol ethanol x (-1366.7 kJ / mol) = -1626.573 kJ

Step 1: Identify the reactants and products.
The student question doesn't provide specific reactants or products. Assuming we have reactant A and product B, let's go through a general mechanism.

Step 2: Identify the nucleophile and electrophile.
Determine which species will act as the nucleophile (electron-rich species) and which will act as the electrophile (electron-poor species) in the reaction.

Step 3: Initial nucleophilic attack.
Using a curved arrow, show the nucleophile donating a pair of electrons to the electrophile. This arrow should start at the electron pair and point towards the electrophilic atom.

Step 4: Show any intermediate species and formal charges.
If any intermediate species are formed during the reaction, draw them and indicate any formal charges on the atoms involved.

Step 5: Proton transfer or elimination (if applicable).
If the reaction involves a proton transfer or elimination, show the movement of electrons using a curved arrow, starting from the electron pair that will be involved and pointing towards the proton being transferred or eliminated.

Step 6: Formation of the final product.
Using curved arrows, show the final steps leading to the formation of product B. Indicate any formal charges if necessary.

Step 7: Review the mechanism.
Ensure that the mechanism you've drawn accurately represents the transformation of reactant A to product B, and that all curved arrows and formal charges are correctly placed.

Based on the concentrations given, the volume of vinegar required is 5.04 mL.

The concentration of a solution is the amount of solute in a given volume of solution.

Concentration can be expressed as:

The concentration of the vinegar solution is 4.76% (w/w). This means that 4.76 g of vinegar is present in 100 g of solution.

Mass of vinegar = 4.76 g

molar mass if vinegar = 60 g/mol

moles of vinegar = 4.76/60 = 0.0793 moles

volume of solution/water = 100 mL or 0.1 L

Molarity of vinegar = 0.0793/0.1 = 0.793 M

1 mole of vinegar reacts with 1 mole of NaOH

let the volume of vinegar required be V

0.793 M × V = 40 × 0.1

V = 4/0.793

V = 5.04 mL

Therefore, the volume of vinegar require is 5.04 mL.

The answer is that they were were not based on evidence and experiment and that made alchemy unscientific in its practices.

Alchemy is an old practice that might be thought of as a forerunner of chemistry.

The term alchemy is derived from the Arabic al-kimiyya, which is derived from Greek. Alchemy's fundamental notions focus around the transformation of one substance into another, often transforming a basic metal like lead or iron into a "noble" metal like silver or gold

The alchemist's main ambitions were to find the Stone of Knowledge, the medium of Eternal Youth and Health, and metal transmutation.

Hydration is a specific example of the phenomenon known generally as a. solvation

The act of hydrating involves combining or dissolving an object in water. It is a particular instance of the more general phenomena known as solvation, which is the process by which solvent molecules surround and scatter a solute to create a homogeneous solution. However, hydration explicitly refers to solvation with water as the solvent.

Solvation may also happen with solvents other than water. Solvation is the process through which a solute and solvent interact to stabilise a solute species. Due to its impact on the solubility, reactivity, and behaviour of compounds in solution, solvation is a crucial mechanism in many chemical and biological processes.
