Question 1

Packaged cake mixes usually contain baking powder, a mixture of sodium hydrogen carbonate and calcium hydrogen phosphate that react to produce carbon dioxide gas when they are heated in water. The CO₂(g)formed allows the cake to "rise." When such cake mixes are used at high altitudes, often the cake will rise too much and collapse, unless special instructions are followed. Why does this happen?

Accepted Answer

The answer of Packaged cake mixes usually contain baking powder,...

Question 2

In an effort to address concerns about global warming, a power plant in Portland, Oregon is designed to take all of its exhaust gases from its boilers and recycle the CO₂ using the Solvay process to make sodium hydrogen carbonate. The reaction is shown below. NH₃(g)+ H₂O(l)+ CO₂(g)+ NaCl(aq)$\rarr$NaHCO₃(aq)+ NH₄Cl(aq) How many liters each of NH₃ and CO₂ (both at STP)would be consumed to produce 3.00 kg of sodium bicarbonate?
