Which of the following statements is true? O a) A polar molecule is neutral in charge. b) A polar molecule has a slight charge. c) A nonpolar molecule dissolves in water. d) A nonpolar molecule only has pure covalent bonds.

For Covalent bonds, answer these three questions: A) Are they found in polar, non-polar or both types of molecules? B) Are they strong or weak? C) Are they found inside a molecule or between a molecule?

This question has multiple parts : Chloroform is a powerful anesthetic and sedative when inhaled or ingested . Its chemical formula is CHCl 3 . ( Cl is chlorine ) (a) Determine the total number of valence electrons for this compound . (b) Based on your structure and VSEPR theory, what is its shape? (dIs the C-blond polar or nonpolar? How do you know? (c) Is the entire molecule polar or nonpolar ? How do you know?

For each row in the table below, decide whether the pair of elements will form a molecular compound held together by covalent chemical bonds. If the elements will form a molecular compound, check the box and enter the chemical formula and name of the compound. (If the elements will form more than one molecular compound, use the compound with the fewest total number of atoms.) You may assume all chemical bonds are single bonds, not double or triple bonds. element pair alo molecular compound will form a element #1 element #2 molecular chemical name compound formula Ar carbon iodine hydrogen bromine lithium охудеn

In a covalent bond between a oxygen atom and a sulfur atom, which of the atoms has a partial positive charge?

Cite two examples of evidence that the name provides for EACH compound.

Please, help with the answer and explain it: Which statement is NOT true about covalent bonds? a) Two atoms complete their outer electron shell by sharing electrons. b) The atoms completely lose or gain electron(s). c) In a diagram, a single covalent bond is drawn as a line between two atoms. d) A pair of electrons is shared between two atoms for each covalent bond. e) Covalent molecules function as stable units
