What is a double bond? What is a triple bond? Compare the bond lengths for single, double and triple bonds between two carbon atoms.

1. a) When calcium forms a compound with chlorine, electrons are transferred from the atom to the atom. b) What type of bonding exists between the calcium and chlorine atoms? c) Indicate the electrical charge on each of the ions and the total electrical charge on the compound. 2. What can be done to an ionic solid so that the ions are capable of motion? 3. How can we cause ions in a solution to move in a specific direction?

According to the belief of early chemists which class of compounds has a special ' life force ' within them

Consider the following chart with ionic and covalent compounds shown. Ionic and Covalent Compounds     Compound Melting Point ⁰C Boiling Point ⁰C W 801 1465 X 2852 3,600 Y 0 100 Z 113 184 Based on the data, which compounds would you classify as ionic or covalent and why? A Compound Y is ionic because its’ melting and boiling points are low.   B Compound Y and Z are covalent because their melting and boiling points are low.   C Compounds W, X, and Z are ionic because their melting and boiling points are high.   D Compounds W, X, and Z are covalent because their melting and boiling points are high.

Please note that "geometry" refers to the molecular or ionic geometry. The Lewis diagram for NICI2 is: :I—N—CI: :CI: The electron-pair geometry around the N atom in NICI 2 is There is/are lone pair(s) around the central atom, so the geometry of NICI 2 is The Lewis diagram for BCI3 is: :CI-B-CI: :CI: The electron-pair geometry around the B atom in BCI3 is There is/are lone pair(s) around the central atom, so the geometry of BCI3 is

1. Sodium, Neon, Oxygen and Argon are elements found on the periodic table Two of these elements that can react together to form a chemical compound. (a) What is the name and the formula of this compound? Name Formula (b) What type of bonding holds this compound together?

Water has many exceptional and useful properties. Which is the rarest property among compounds? Water has a high heat capacity. Solid water is less dense than liquid water. Water is a solvent. Water has surface tension.

10.) The structural formula of a certain aldehyde (related to formaldehyde) is H3C-CH2-CHO.  Draw a Lewis structure for this aldehyde and determine the number of bonds present.  Note that a single or a double or a triple bond counts as one bond. Write the number, not the word.

CCI, is a nonpolar molecule, while CHCI3 and CH2Cl2 are polar molecules. Draw the Lewis structures of these three molecules. Explain the observation in polarity of the molecules. 2.
