Part D Complete the table by writing the name or formula of each compound and the type of bonding that uses. You may refer to this list of polyatomic ions. x X, 三=星E 三三 Font Sizes Formula Type of Bonding (ionic/covalent/both) Name S2F10 covalent calcium sulfide P2l4 dinitrogen monoxide AICI3 copper(Il) hydroxide BaSO4 butane Characters used: 172/ 15000

Naming Covalent Compounds Although the names end in "-ide", naming for covalent is different than for ionic. We must use prefixes to specify how many of each element are present in the formula. A prefix is used for each element except when the first element has only one. Never start the name with "mono". See examples below. The following prefixes are used in covalent compounds: Formula Name nitrogen dioxide dinitrogen trioxide NO2 mono- means 1 N203 di- means carbon tetrachloride tri- means 3 dichlorine monoxide Cl20 S2C12 tetra- means 4 disulfur dichloride penta- means hexa- 5 means

1. C3H8 though covalently bonded cannot be named as tricarbon octahydride. Which of the following premise supports this? O The hydrogen acts as cation. O The compound is not an empirical formula O The name follows ionic compound O The number of atoms need not to be specified O C₂Hs is a hydrocarbon 2. Tritium, 1 3 3/1t, a radioactive isotope of hydrogen, slowly turns into a helium isotope, 2 3 He 3/2He. Which of the following is correct about the two isotopes? O They have the same number of neutral subatomic particles O Their cations are deflected to the same point in a magnetic field whose strength is varied OTheir cations are deflected to the same point in a magnetic field whose strength is not varied O They have the same nuclear charge O They have the same number of charges in subatomic particles.

Compounds such as Freon® 112 (referred to as chlorofluorocarbons, or CFCs) were used as refrigerants for many years, but they were phased out because of their harmful effects on Earth's atmosphere. Write the molecular and empirical formulas for Freon 112. The Lewis dot structure of Freon 112. There are two central carbon atoms bonded together through a single bond. Each carbon atom is bonded to two chlorine atoms and one fluorine atom through single bonds. Each chlorine atom has 3 lone pairs. Each fluorine atom has 3 lone pairs.
