What example illustrates adhesion?
What example illustrates adhesion?
Adhesion and Cohesion of Water. The water drop is composed of water molecules that like to stick together, an example of the property of cohesion. The water drop is stuck to the end of the pine needles, which is an example of theproperty of adhesion.
Which example illustrates adhesion Brainly?
Answer: water droplets sticking to a window. Explanation: adhesion means sticking to, such as adhesive dressing tape, which is fabric that sticks to itself for injuries.
Which points in the water cycle below best illustrates water changing to a gas and which term could describe it?
The answer is evaporation. This is because sublimination is a solid immediately changing to a gas, without passing through liquid state. Hoped I helped.
What is demonstrated by water moving up a straw quizlet?
What is demonstrated by water moving up a straw? The water will remain the same.
Which is least likely to be a reservoir for fresh water?
ocean water
What is demonstrated by water moving up a straw?
The correct answer is cohesion and adhesion. Water moving up a straw is an example of the motion of water against gravity which depends on the attraction between water molecules and the walls of the straw (adhesion), and also on the attraction between water molecules (cohesion).
What does the dotted line between the water molecules represent?
The positive charge of the hydrogen from one molecule attracts the negatively charged oxygen atom of another water molecule. As a result, an inter molecule hydrogen bonding is formed. Hence, the dotted line represents a hydrogen bond.
Which of the following best explains how water is able to move upward from the roots of a plant?
xylem. Explanation: water is able to move upward from the roots of a plant, through its xytem in the stem, and out to the leaves because Water and the xylem are both polar.
Which bonds are found inside a water molecule between hydrogen and oxygen quizlet?
Terms in this set (17) A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The covalent bonds are polar because oxygen is more attractive to electrons than hydrogen, causing the oxygen to have a slightly negative charge and hydrogen to have a slightly positive charge.
What type of bond is found between the oxygen and hydrogen atoms within a water molecule?
Covalent bonds
What kinds of bonds are between the oxygen and hydrogen in a water molecule?
The covalent bonds between hydrogen and oxygen atoms in water are polar covalent bonds. The shared electrons spend more time near the oxygen nucleus, giving it a small negative charge, than they spend near the hydrogen nuclei, giving these molecules a small positive charge.
What does this mean how does this property make hydrogen bonds between water molecules possible?
In water molecules the oxygen atom attracts the negatively charged electrons more strongly than the hydrogen. When an ionic or polar compound is exposed to water, the water molecules surround it. Because the water molecules are small, many of them can surround one molecule of the solute and form hydrogen bonds.
How do you tell if a molecule will form hydrogen bonds with water?
If there is a lone pair of electrons belonging to nitrogen, oxygen, or fluorine, then it is possible to bond to water. Therefore, it is can accept a hydrogen.
Do water molecules have a strong attraction to each other?
Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.
What is the attraction between water molecules called?
In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
Can CH3OCH3 form hydrogen bonds with water?
The ether, CH3OCH3, can only accept a hydrogen bond from water.
Can ch3oh form hydrogen bonds with itself?
Only CH₃NH₂ and CH₃OH can have hydrogen bonds between other molecules of the same kind. To have hydrogen bonding, you need an N, O, or F atom in one molecule and an H attached to an N, O, or F atom in another molecule. CH₃OH has an O atom and an O-H bond. It can form hydrogen bonds with other CH₃OH molecules.
Can CH3F form hydrogen bonds?
(d) CH3F(l) – Dipole – dipole forces: CH3F is a polar molecule, it has a permanent dipole. In this case hydrogen bonding does NOT occur, since the F atom is bonded to the central C atom (F must be bonded to H in order for hydrogen bonding to occur).
Does ethane form hydrogen bonds with water?
Will ethane form a hydrogen bond with water? Why or why not? No, ethane will not form a hydrogen bond, or ionic bond with water or any other polar molecule because it is nonpolar.
Why is hydrogen bond stronger in water than alcohol?
The hydrogen atoms are slightly positive because the bonding electrons are pulled toward the very electronegative oxygen atoms. Hydrogen bonds are much stronger than these, and therefore it takes more energy to separate alcohol molecules than it does to separate alkane molecules.
Does boiling break bonds?
Intermolecular forces are much weaker than the strong covalent bonds in molecules. When simple molecular substances melt or boil, it is these weak intermolecular forces that are overcome. The covalent bonds are not broken.
Which type of IMF is the weakest?
London dispersion forces
What increases boiling point?
The key thing to consider here is that boiling points reflect the strength of forces between molecules. The more they stick together, the more energy it will take to blast them into the atmosphere as gases. Boiling points increase as the number of carbons is increased. Branching decreases boiling point.
What is the strongest intermolecular force in water?
hydrogen bonds
What has the strongest intermolecular forces solid liquid or gas?
Yes, intermolecular forces are the strongest in solids. “In solids, the intermolecular forces are very strong, and the constituent particles are closely packed. That is why; solids are incompressible and have high density
What is the strongest intermolecular force present in carbon monoxide?
The dipole-dipole attractions between CO molecules are comparably stronger than the dispersion forces between nonpolar N2 molecules, so CO is expected to have the higher boiling point.
