Which term best describes the substances that cause oil and water molecules in salad dressing to interact and mix?
The substances that cause oil and water molecules in salad dressing to interact and mix are called emulsifiers. Emulsifiers have both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, allowing them to stabilize the mixture of oil and water. Common examples of emulsifiers in salad dressings include mustard, egg yolk, and vinegar. These agents help create a stable emulsion, preventing the oil and water from separating.

What best describes how molecules interact with systems in the human body?
you need the molecules to make the tissue.
What is a solvent and how does it interact with other substances?
A solvent is a substance that can dissolve other substances, forming a solution. Solvents interact with other substances by surrounding and breaking apart their molecules, allowing them to mix evenly. This process is known as dissolution.
Substances that can separate in water?
Substances that can separate in water are polar or ionic compounds that interact with water molecules to break apart into ions or molecules. This can include salts like sodium chloride, sugar, and acids like hydrochloric acid. These substances dissolve in water by forming hydrogen bonds with the water molecules.
What hydrophilic substances are made of?
Hydrophilic substances are typically made of polar molecules, such as water and other compounds containing hydroxyl groups (-OH), carbonyl groups (C=O), or amino groups (-NH2). These groups enable the substances to interact with water molecules, leading to their dissolution or dispersion in water.
What do all substances have?
atoms! also, you can say that all substances have physical and chemical properties.
What determines whether a substance is hydrophobic or hydrophilic?
The chemical structure of a substance determines whether it is hydrophobic (repels water) or hydrophilic (attracts water). Hydrophobic substances have non-polar molecules that do not interact well with water, while hydrophilic substances have polar molecules that can form bonds with water molecules.
How does water interact with non polar substances?
Water does not interact well with nonpolar substances because they do not have large enough dipoles to cause water to interact with them and not other water molecules. Water is said to squeeze nonpolar molecules together because of the hydrophobic effect it of nonpolar compounds.
What interferes with hydrogen bonding between water molecules?
Substances that disrupt hydrogen bonding between water molecules include solutes like salts, acids, and bases, as well as nonpolar substances like oil. These substances can prevent water molecules from forming hydrogen bonds with each other by either competing for hydrogen bond formation or interfering with the water molecules' ability to interact.
What types of substances dissolve in water?
Substances that dissolve in water are typically polar molecules or ionic compounds. Polar molecules have a positive and negative end, allowing them to interact with water molecules through hydrogen bonding. Ionic compounds dissociate into ions in water due to their charges being attracted to the polar water molecules.
Ionic and polar substances dissolve in water because water is ..?
polar, meaning it has a positive and negative end that can interact with the charged or partial-charged molecules of ionic and polar substances through electrostatic interactions. This allows water molecules to surround and break apart these substances, facilitating their dissolution in water.
Can you explain the diagram of molecules and how it relates to chemical reactions?
The diagram of molecules shows how atoms are arranged in a molecule. In chemical reactions, molecules interact and rearrange their atoms to form new substances. The diagram helps us understand how molecules change during a chemical reaction.
Which kind of energy is transferred between molecules of touching substances during conduction?
The energy transferred between molecules of touching substances during conduction is primarily in the form of heat. This occurs through the vibration and collision of molecules as they interact with one another.
