Which statement best describes the compressibility of a gas? A Increasing the temperature of a gas decreases the pressure. B Increasing the temperature of a gas increases the pressure. C Increasing the pressure on a gas decreases the volume.

How many grams are in 3.0 moles of KCI (potassium chloride) ?

3 During a flame test, a lithium salt produces a characteristic red flame. This red color is produced when electrons in excited lithium atoms (1) are lost by the atoms (2) are gained by the atoms (3) return to lower energy states within the atoms
