Acids are neutralized by bases (also known as alkaline chemicals). The process of neutralization produces water and salt. As for carbon dioxide, that would not be a product of most neutralization reactions; it is much more likely to be the product of combustion.
Calcium sulfate, water and carbon dioxide
Combining carbon dioxide and water is a chemical change, not a physical change, but it doesn't make sugar. Carbon dioxide and water makes carbonic acid. CO2 + H2O <--> H2CO3-->H+ + HCO3-
Yes.
zinc carbonate + sulphuric acid = zinc sulphate + water + carbon dioxide
Carbon dioxide and water
Carbon dioxide (CO2) mixes with water to make a weak carbonic acid
H2CO3, or carbonic acid, can be formed by dissolving carbon dioxide (CO2) in water (H2O). When carbon dioxide is dissolved in water, carbonic acid "exists in equilibrium" with the water and carbon dioxide; meaning that the carbon, oxygen, and hydrogen atoms involved tend to move around and keep equal concentrations of gas/water mixture and carbonic acid.

when carbon oxidizes (mixes with oxygen) it forms carbon dioxide
Mother nature has a way of absorbing carbon dioxide. It's called rain. Rain water combines with carbon dioxide to make carbolic acid. The carbolic acid falls to the earth and combines with rock and dirt to make a soft rock. People down wind of large smokestacks have a problem with the acid rain. Too much acid rain will kill trees. Planet earth does not get enough rain to remove the increasing amounts of carbon dioxide we are putting into the atmosphere. The carbon dioxide we are making adds to the problem of global warming.   I have wondered if putting water sprayers into our smokestacks will remove the carbon dioxide making acid water. That acid water can be mixed with soil to make soft rock. The soft rock can be used for landfill. Perhaps we can remove carbon dioxide in our smokestacks before it gets into our atmosphere in this way?
Carbon dioxide and water
I'm not sure about lemonade, but carbon dioxide is added to make soda fizzy. Carbon Dioxide (CO2) is a gas that can bind to water (H2O) molecules when it dissolves to form H2CO3, which is a weak acid known as Carbonic Acid.
an effervescent drink that releases carbon dioxide under conditions of normal atmospheric pressure. Carbonation may occur naturally in spring water that has absorbed carbon dioxide at high pressures underground. It can also be a byproduct of fermentation, such as http://www.answers.com/topic/beer and some wines (see http://www.answers.com/topic/champagne-1).
The acetic acid in the vinegar reacts with the sodium bicarbonate to produce carbonic acid, which rapidly decomposes into carbon dioxide gas (CO2) and water. The gas created is mostly carbon dioxide.
