Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. a HF + b H20 = c H3F Step 2: Create a System of Equations Create an equation for each element (H, F) where each term represents the number of atoms of the element in each...
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states ...
Is HF an element or compound? Decide whether each of the compounds listed is polar or nonpolar. If polar, show the dipole moment. (Hint: You may need to draw out the Lewis structure to determine the polarity and to show the dipole moment.) a. HCl b. PH3 c. CF4 Is CH3Cl polar or...
