Which statement is true about water molecules
Which is true about water molecule?
Water Molecule — Chemical and Physical Properties. Water is a chemical compound and polar molecule, which is liquid at standard temperature and pressure. It has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom.
Which of the following statements about water molecules is correct?
Answer: The true statements are: Water molecules move randomly around each other. The oxygen atom has a negative charge.
Which is correct in a water molecule?
Detailed Solution. Option 3 is Correct. The water molecule has a bent-shaped structure. In water, two hydrogen atoms are attached to one central atom of oxygen by covalent bond, making an angular spatial structure.
Are water molecules polar or nonpolar?
Water is a Polar Covalent Molecule
The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles – a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
Which of the following is not true about water molecule?
The following is not true about water molecules: c) Water molecules form ionic bonds. Rather, water molecules form hydrogen bonds with each other due…
Which statement best explains why water is an important molecule for living things?
Living organisms need water to survive. … Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.
Which statement best describes why a water molecule is polar?
Water is a polar molecule because the bonds between oxygen and hydrogen are polar covalent bonds. This means that although they form covalent bonds (normally non-polar) the difference in electronegativity is great enough to make one side more negative (oxygen side) and the other side more positive (hydrogen side).
What is it called when water molecules are attracted to other water molecules?
The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid. … The attraction between individual water molecules creates a bond known as a hydrogen bond.
What kind of bonds form between water molecules?
Strong linkages—called covalent bonds—hold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other.
Which statement best describes why a water molecule is polar quizlet?
Which statement best describes why a water molecule is polar? Oxygen exerts a stronger pull on the shared electrons than the hydrogens do. Oxygen is bigger than hydrogen, giving it a stronger positive charge.
Which statement correctly describes the electrons in a water molecule?
Which statement correctly describes the electrons in a water molecule? Electrons are pulled closer to the oxygen atom. How does a catalyst influence a chemical reaction?
Why is water a polar molecule quizlet?
Water is considered a polar molecule because one side of the molecule is a different charge then the other side of the molecule. Occurs when hydrogen bonds together. … The hydrogen atoms in water bond to the hydrogen atoms in the air, creating a greater surface tension than most other liquids.
Which is true about the polarity of the water molecule?
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
Which describes one of the properties of a water molecule?
Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons. Water is an excellent solvent.
Which statement is true about the electrons in each polar bond of a water molecule?
Which statement is true about the electrons in each polar bond of a water molecule? They are more attracted by the oxygen atom than by the hydrogen atom. Which best explains why water has a high specific heat?
Which is most likely true about water chemical systems?
Which is most likely true about water in chemical systems? Water dissociates ionic compounds. Water is called the “universal solvent.” Which statement best explains this description with respect to ionic compounds? Water can dissociate many ionic compounds through ion-dipole interactions.
Is water a polar molecule True or false?
A water molecule (H2O) is polar. This means that it has a slight negative charge near the oxygen atom and a slight positive charge near the hydrogen atoms.
Why is the polarity of a water molecule important?
Polarity simply means that the molecule has both a positively and negatively charged end. More important, the polarity of water is responsible for effectively dissolving other polar molecules, such as sugars and ionic compounds such as salt. Ionic compounds dissolve in water to form ions.
Is water molecule or compound?
Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.
Which statement best explains why water is known as the universal solvent quizlet?
Which statement best explains why water is known as the universal solvent? Water has the ability to dissolve more substances than any other liquid.
How water molecule is formed?
When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. An example of a simple chemical reaction is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H2O2).
Is water wet article?
Water isn’t wet because it is a liquid that wets things. Once you come into contact with water you become wet. Until then water is liquid and you are dry.
Is water a molecular substance?
Water as a Compound and Molecule
The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It’s also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other.
