Hydrogen bonding, though it is technically an intermolecular force rather than an actual bond.
What else can I help you with?
What is the type of bond that forms between water molecules and contributes to cohesion?
Hydrogen bonding is the type of bond that forms between water molecules and contributes to cohesion. It occurs between the hydrogen atom of one water molecule and the oxygen atom of another water molecule.
What name is given to the bond between water molecules?
The bond between water molecules is called the hydrogen bond.
Which fundamental force contributes to oressure in both water and the atmosphere?
The electromagnetic force contributes to pressure in both water and the atmosphere. In water, this force between water molecules results in pressure, while in the atmosphere, the force between air molecules creates atmospheric pressure.
Why starch forms gel in water?
Starch forms a gel in water due to the interaction between starch molecules and water molecules. When starch is heated in water, the granules swell and absorb water, causing them to burst and release amylose and amylopectin molecules. These molecules form a network that traps water, leading to the formation of a gel.
What is the dehydration reaction that forms bonds between molecules?
The dehydration reaction that forms bonds between molecules is typically a condensation reaction. In this process, a water molecule is removed to form a bond between two molecules. It is a common mechanism for building larger molecules like proteins, carbohydrates, and nucleic acids.
What kind of bond does water commonly make?
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
How many carbon dioxide Molecules are in water?
Carbon dioxide is unstable in water. It forms a equilibrium changing between aqueous and gaseous form. This makes it impossible to tell how many molecules are in water.
How does the presence of a hydrogen bond between two water molecules contribute to the unique properties of water?
The presence of hydrogen bonds between water molecules contributes to the unique properties of water by giving it a high surface tension, cohesion, and the ability to moderate temperature effectively.
What kind of bonding does water make?
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
Why does a concave meniscus form when water is in a graduated cylinder?
A concave meniscus forms in a graduated cylinder with water due to adhesive forces between the water molecules and the walls of the cylinder. This causes the water to cling to the walls, resulting in a concave shape.
Describe an example of cohesion and adhesion that you might observe during your daily life?
An example of cohesion is when water forms droplets on a leaf due to the attraction between water molecules. An example of adhesion is water sticking to the sides of a glass due to the attraction between water molecules and the glass molecules.
What is the scientific name when sugar dissolves in water?
When sugar dissolves in water, it forms a homogeneous solution, with sugar molecules (sucrose) dispersed throughout the water molecules. The process is a physical change, not a chemical reaction, and involves the breaking of intermolecular forces between the sugar molecules, allowing them to mix with the water molecules.
