$$\mathrm{Cl}_{2}(a q)+2 \mathrm{NaBr}(a q) & \longrightarrow 2 \mathrm{NaCl}(a q)+\mathrm{Br}_{2}(a q)$$

(a) Which elemental halogen would you predict is the most stable, upon mixing with other halides?

(b) Predict whether a reaction will occur when elemental chlorine and potassium iodide are mixed.

(c) Predict whether a reaction will occur when elemental bromine and lithium chloride are mixed.

Br2(aq) + 2 NaI(aq) \longrightarrow 2 NaBr(aq) + I2(aq)

Cl2(aq) + 2 NaBr(aq) \longrightarrow 2 NaCl(aq) + Br2(aq)

Step-by-Step Solution:

Step 1 of 5) Natural gas consists of gaseous hydrocarbons, compounds of hydrogen and carbon. It contains primarily methane 1CH42, with small amounts of ethane 1C2H62, propane 1C3H82, and butane 1C4H102. We determined the fuel value of propane in Sample Exercise 5.10.Natural gas burns with far fewer by-products and produces less CO2 than either petroleum or coal. Petroleum is a liquid composed of hundreds of compounds, most of which are hydrocarbons, with the remainder being chiefly organic compounds containing sulfur, nitrogen, or oxygen. Coal, which is solid, contains hydrocarbons of high molecular weight as well as compounds containing sulfur, oxygen, or nitrogen. Coal is the most abundant fossil fuel; current reserves are projected to last for well over 100 years at current consumption rates. However, the use of coal presents a number of problems.
