2Nal + Cl2 → 2NACI + I2 How many grams of iodine are liberated if 546 g of chlorine react with excess sodium iodide? (I'm a really busy AP student with a lot of homework. Just need the work and answer!)

Convert 25 gram of carbon dioxide to mold

Which of the following is true? A) Gas atoms subjected to electricity emit bright lines of light. B) Gas atoms absorb white and emit a continuous spectrum of light. C) Gas atoms under high pressure emit dark lines against a continuous spectrum.

The reaction Ba (NO3) 2 (aq) + Na2SO4 (aq) → 2NaNO3 (aq) + BaSO4 (s) goes to completion because a

Consider the following reaction: AB (s) ⇌A (g) + B (g). At equilibrium, a 10.9 L container at 650 K contains A (g) at a pressure of 0.126 atm and B (g) at a pressure of 0.23 atm. The container is then compressed to half of its original volume.
