A. Lock all have actually an incomplete valence electron shell. B. Lock all have actually the same number of protons in your nuclei. C. They space all typically unreactive elements. D. Castle all have actually the same number of electrons in their an initial electron shell.
You are watching: What explains the negative charge on the oxygen atom within the water molecule
Which the the complying with accurately explains what is occurring in the depicted reaction?
A. A single covalent bond is formed in between carbon and each the the four hydrogen atoms. B. A hydrogen link is formed between carbon and the four hydrogen atoms. C. A quadruple covalent link is formed between carbon and also one hydrogen atom. D. An ionic link is formed in between carbon and the four hydrogen atoms.
What describes the an adverse charge on the oxygen atom in ~ the water molecule?
A. Protons space transferred indigenous oxygen to hydrogen during the development of an ionic bond. B. Oxygen atoms have actually a stronger pull top top the electrons common within a covalent bond formed between oxygen and also hydrogen. C. Hydrogen atoms have a more powerful pull top top the electrons shared within a covalent link formed in between oxygen and also hydrogen. D. Electrons room transferred native hydrogen come oxygen throughout the development of one ionic bond.
B. Oxygen atoms have actually a more powerful pull on the electrons common within a covalent link formed in between oxygen and hydrogen.
What is the group of a equipment with a pH the 8.3?A. Buffered equipment B. Alkaline equipment C. Neutral systems D. Acidic solution
All amino acids (such together the four represented in the figure) save on computer ______.
A. Phosphorous and nitrogen B. A nitrogen-containing base and also a pentose street C. One amine group and also a carboxyl team D. One amine group and also a fatty acid
Which that the complying with statements is true regarding the enzyme-catalyzed reaction (B) contrasted to the uncatalyzed reaction (A)?
A. The reaction in the existence of enzyme releases an ext energy. B. The commodities of the reaction through enzyme contain an ext chemical potential energy. C. The reaction in the visibility of enzyme will type larger products. D. Less energy input is required to start the reaction in the existence of enzyme. E. All of the listed responses are true.
Which essential molecules form the major structural materials of the body?A. Main point acids B. Lipids C. Carbohydrate D. Proteins
Foods are broken down into their structure blocks by including water. This would certainly be an example of i m sorry characteristic that water?A. Water acts as a lubricant.B. Water acts together a reactant.C. Water acts together a cushion.D. Water has actually a high heat of vaporization.
Water acts to dissolve molecule in the body. Just how does water dissolve the salt (NaCl) in her mouth indigenous a salty pretzel?A. Water acts together a cofactor because that enzymes that dissolve the salt.B. Once water is included to the NaCl, NaCl is broken down by including OH- come one element and also H+ to the other. This is known as hydrolysis.C. Water acts together a solvent due to the fact that the partial negative charge top top the oxygen in water attracts sodium, when the partial confident charge on hydrogen attracts chloride. This results in the separation of salt from chloride, for this reason breaking the ionic bond.
C. Water acts together a solvent because the partial an adverse charge top top the oxygen in water attractive sodium, if the partial positive charge ~ above hydrogen attracts chloride. This results in the separation of sodium from chloride, thus breaking the ionic bond.
