An ultrasound tech is trying to identify an object, but the machine is broken and is not sending out the sound wave. which statement best describes this situation? the generated sound wave will not be able to reflect off of the object. the sound wave will not be generated, so there will be no echoes received. the echoes will be made but will be unable to be received by the machine. the machine will not be able to process the received echoes into images.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
