Carbon Dioxide
This gas is carbon dioxide (CO2).
All four cases produce carbon dioxide gas. In the first case, acid rain reacts with limestone to produce carbon dioxide. When a candle burns, it also produces carbon dioxide. Similarly, a dog panting expels carbon dioxide through respiration. Finally, fermenting grapes release carbon dioxide as a byproduct of the fermentation process.
Calcium carbonate, limestone, is baked in a kiln to produce quicklime, calcium oxide.
Ethanol produces around 80% by fermenting 100g of sugar produce.
No. Sugar and a fermenting agent eg yeast is needed to produce alcohol.
Cane
It depends on what is fermenting. Cow poo, produces methane. Fruits produce alcohol.
By fermenting it with certain anaerobic bacteria.
Limestone is obtained through mining or quarrying. Large deposits of limestone can be found in many parts of the world and are typically extracted using heavy machinery and explosives. After extraction, the limestone is processed and crushed into various sizes for use in construction, agriculture, and other industries.
Calcium oxide
Yes, burning wood can produce carbon monoxide.
Limestone is crushed and baked at high temperatures to produce the main ingredient for Portland cement.
