Use the half-reaction method to balance the following equation, which is in an acidic solution:
ClO-3 (aq) + I- (aq)
→ I2 (s) + Cl- (aq).

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

The following reaction shows sodium carbonate reacting with calcium hydroxide. na2co3 + ca(oh)2 → naoh + caco3 how many grams of naoh are produced from 20.0 grams of na2co3? (molar mass of na = 22.989 g/mol, c = 12.01 g/mol, o = 15.999 g/mol, ca = 40.078 g/mol, h = 1.008 g/mol) 12.2 grams 15.1 grams 24.4 grams 30.2 grams
