Why does coke have a higher boiling point than Mountain Dew?
Coke has a higher boiling point than Mountain Dew because it has a higher concentration of dissolved substances, such as sugar and caramel coloring, which increases its boiling point. Mountain Dew, on the other hand, has a lower concentration of dissolved substances, which results in a lower boiling point.
What properties of a substance determines how that substances will react when combined with other substances?
The chemical structure of a substance, the presence of functional groups, and its reactivity are key factors that determine how a substance will react when combined with other substances. Additionally, factors such as polarity, acidity, and basicity also play a role in interactions between substances.
1 How do you know that two substances get different charges when they are rubbed together?
You can use the electrostatic series to determine charge by looking at the substances higher on the list will always lose electrons and becomes positively charged and the substances lower on the list always gains electrons and becomes negatively charged
How do you make 100 percent of ethanol from 80 percent ethanol?
To increase the concentration of ethanol from 80% to 100%, you can use a process called distillation. By distilling the 80% ethanol solution, you can separate the ethanol from the water and other impurities, resulting in a higher concentration of ethanol.
Why do some substance float on top of the other substances when layered?
Substances float on top of others based on their densities. When two or more substances are layered, the one with the lower density will float above the one with a higher density. This is governed by Archimedes' principle, which states that an object will float if it displaces a volume of fluid equal to its weight. Consequently, substances with different densities will stratify, with less dense substances on top.
What is the difference between an acidity and pH?
Acidity refers to the presence of acidic substances in a solution, while pH is a measure of the concentration of hydrogen ions in a solution on a scale from 0 to 14, with lower values indicating higher acidity. So, acidity describes the nature of a substance, while pH quantifies the level of acidity.
Why is a solution considered an acid?
A solution is considered an acid if it has a pH level less than 7. Acids release hydrogen ions (H+) when dissolved in water, which can react with other substances to donate a proton. The pH scale measures the concentration of hydrogen ions in a solution - the lower the pH, the higher the acidity.

Coke has a higher boiling point than Mountain Dew because it has a higher concentration of dissolved substances, such as sugar and caramel coloring, which increases its boiling point. Mountain Dew, on the other hand, has a lower concentration of dissolved substances, which results in a lower boiling point.
Properties that depend on the substances reaction with other substances?
Chemical properties depend on how a substance interacts with other substances, indicating its reactivity, stability, and ability to undergo chemical changes. These properties can include flammability, acidity, and corrosion resistance.

How do acids work?
Acids release hydrogen ions (H+) when dissolved in water, which can then react with other substances to form new chemical compounds. The concentration of hydrogen ions determines the acidity of a solution, with lower pH values indicating stronger acidity. Acids can donate protons to other substances, known as proton donation, and can also corrode certain materials due to their reactivity.
What is Arabica coffee and what sets it apart from other types of coffee beans?
Arabica coffee is a type of coffee bean known for its smooth flavor and aroma. It is considered higher quality than other types of coffee beans, such as Robusta, due to its lower caffeine content, more complex flavors, and higher acidity.
What is the specific heat of alcohol and how does it compare to other substances?
The specific heat of alcohol is around 2.44 J/gC, which is lower than water but higher than most other substances. This means that alcohol requires less energy to change its temperature compared to water, but more than many other materials.
When two substances come into contact with each other the substance will transfer heat to the substance?
When two substances come into contact, heat will flow from the substance with higher temperature to the substance with lower temperature. This transfer of heat will continue until thermal equilibrium is reached, where both substances have the same temperature.

Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.

To increase the concentration of ethanol from 80% to 100%, you can use a process called distillation. By distilling the 80% ethanol solution, you can separate the ethanol from the water and other impurities, resulting in a higher concentration of ethanol.
