Potassium iodide is added to table salt to prevent iodine deficiency and thyroid gland problems. Given their location on the periodic table, identify the ionic charge for each element and predict the chemical formula of the compound formed.
A) Potassium, K, is an alkali metal and is in Group IA with an ionic charge of +1. While iodine, I, is a halogen and is in Group VIIA with a charge of -1. These will form KI(s).
B) Potassium, K, is an alkaline earth metal and is in Group IA with an ionic charge of +2. While iodine, I, is a halogen and is in Group VIIA with a charge of -1. These will form KI2(s).
C) Potassium, K, is an alkali earth metal and is in Group IA with an ionic charge of +2. While iodine, I, is a noble gas and is in Group VIA with a charge of -2. These will form K2I2(s).
D) Potassium, K, is an alkali earth metal and is in Group IA with an ionic charge of +1. While iodine, I, is a diatomic gas and is in Group VIA with a charge of -2. These will form K2I(s).

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
