Which property of water best explains the high surface tension?

Which property of water best explains the high surface tension?

Cohesion

What property of water allows for surface tension?

What is the property of water causing an attraction between water and a different substance?

Water Is Cohesive In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass.

Why does water have an increased surface tension compared to most other liquids?

Why does water have an increased surface tension compared to most other liquids? Water has an unusually high surface tension due to hydrogen bonding between the molecules at the air-water interface and to the water below. Polarity allows water molecules to form hydrogen bonds with each other.

Which has more surface tension water or oil?

Water has a high surface tension (72 dynes/cm). Oil differs from water in many respects, the most important of which is surface tension. Oil has a surface tension of 30–35 dynes/cm, meaning that oil-soluble fatty surfactants do not provide the desired surface tension reduction for oils.

Why does soap decrease the surface tension of of water quizlet?

Why does soap decrease the surface tension of of water? It keeps water molecules away from the surface. It decreases the amount of intermolecular attraction between the water molecules. It increases the capillary action of the water.

Which of these best explains why a paper clip can float on water 2 points?

The paperclip will float on the surface of the water because of the property of water known as surface tension. Surface tension is defined as the attraction on the water of like particles to one another.

What happens to a soda can left in the freezer why quizlet?

What happens to a soda can left in the freezer? Why? The soda can puffs out and sometimes the lid pops open because water expands when it freezes.

Which statement best describes what is happening at the surface of liquid water?

Which statement best describes what is happening at the surface of liquid water? At the surface there is a constant exchange of liquid and gaseous water. Slow moving gas molecules are captured by the liquid water. Fast moving water molecules leave the surface and become gas molecules.

Which statement best describes why water is an effective solvent?

Which statement best describes why water is an effective solvent? Water’s relatively small size allows it to fit between individual atoms, driving them apart. Water’s hydrophobic nature separates polar and non-polar substances. Water’s polarity allows it to dissolve ionic and polar compounds.

Which is a property of every heterogeneous mixture?

Which is a property of every heterogeneous mixture? The mixture is made up of at least two different states. The mixture is made up of something dissolved in a liquid. The composition of the mixture is the same throughout.

Which is a property of every mixture?

Answer. One substance can be separated from another through physical means is a property of every mixture. Mixtures are made up of two or more substances that are different. It is the product of mechanical or chemical substance blending or mixing.

What is a property of every homogeneous mixture?

Each part of the mixture has the same appearance. The mixture is made up of a solid dissolved in a liquid. The characteristics of the mixture change within a single sample. The components of the mixture change within a single sample.

Which best describes mixture?

A mixture is a combination of two or more substances in which the identities of substances are retained. The mixture can be in the form of solutions, colloids and suspension. The mixture will have characteristics different from the parent material due to the combination of different kinds of materials.

Which property best describes a mixture?

It has a single chemical composition. It can appear different from different sources. It cannot be described by a chemical symbol or formula. It cannot have more than one state of matter.

What best describes uniform mixture?

Answer. Another word for a uniform mixture is a homogeneous mixture. There is only one phase (state of matter) observed in a uniform, homogeneous mixture.

Which property describes a mixture It Cannot be separated?

It cannot be separated by physical methods. It has a single chemical composition.

Which type of reaction has the general formula of AB CD → AD CB?

replacement reaction

What are the 4 types of reactions?

Four basic types Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.

What are the 3 major types of chemical reactions?

Types of Chemical Reactions

  • Synthesis reactions. Two or more reactants combine to make 1 new product.
  • Decomposition reactions. A single reactant breaks down to form 2 or more products.
  • Single-replacement reactions. A single element replaces a similar element of an adjacent reactant compound.
  • Double-replacement reactions.
  • Combustion reactions.

Which type of reaction has the general formula?

A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).

Which type of reaction has the general formula of AB?

7.10: Classifying Chemical Reactions

Name of Reaction General Form
Exchange: Single Replacement AB + C → AC + B
Exchange: Double Replacement AB + CD → AD + CB
Combination (Synthesis) A + B → AB
Decomposition AB → A + B

What are five general types of reactions?

In this lesson, students will be guided through definitions, generic formulas and actual chemical examples regarding the five types of reactions (i.e., synthesis, decomposition, single-replacement, double-replacement, and combustion).
