Document Summary
Radio waves travel at the speed of light which is 3. 00 x 108 m/s. Lithium forms compounds which are used in dry cells and storage batteries and in high-temperature lubricants. It has two naturally occurring isotopes 6li (isotopic mass=6. 015121 amu) and 7li (isotopic mass=7. 016003 amu). True or false: an ionizable hydrogen atom is a hydrogen atom that separates from the molecule when the molecule is dissolved in a solution and becomes a hydrogen ion, h+. Household sugar, sucrose, has the molecular formula c12h22o10. True or false: in a correctly balanced equation, the number of reactant molecules must equal the number of product molecules. Write the chemical formula, including its charge, of the ion carbonate. co3. The substance present in the largest amount is referred to as the solvent. A solution is a homoygeneous mixture of two or more substances. Any substance present in a smaller amount is called the solute.
