What is a buffer tank in wastewater plant?

A buffer tank adds carbon dioxide to wastewater. How much carbon dioxide is added and dissolved in the water affects the pH. In short, a buffer tank is used to adjust the pH of water during treatment.

How does the fish get its oxygen and how does carbon dioxide is removed?

The water that the fish swims in passes over the gills - these work like our own lungs - taking in oxygen, and expelling carbon dioxide. This is why you need to change the water in the tank on a regular basis - because the level of carbon dioxide increases daily.

Can you make soda fizzy again?

You could if you have a tank of carbon dioxide handy. However, it is probably not worthwhile.


What test can you carry out to show that carbon dioxide is denser than air?

One of my favorites is to get a big bath jar and put dry ice in the bottom. Cover it (loosely) to keep air from stirring it up and let some of the dry ice evaporate. IF carbon dioxide is heavier than air, the carbon dioxide will fill the bottom of the bath, and you can float a soap bubble filled with ordinary air on the heavier carbon dioxide layer. Try it and see.You could also construct an apparatus with candles at various heights and connect it with tubing to a carbon dioxide source (such as a compressed gas cylinder). As the carbon dioxide enters the tank with the candles, it should fill up the tank in such a way that the lowest candles are extinguished first.


The burning of fuel such as propane releases?

The formula for the combustion of propane is: C2H6 + 5O2 --> 2CO2 + 3H2O So each mole of propane creates two moles of carbon dioxide. One mole of propane is 30 g, one mole of carbon dioxide is 44 g So each gram of propane creates (2x44)/30)= 2.93 g of carbon dioxide on combustion. In common terms a 20lb tank of p for a BBQ creates a bit less than 60 lb of carbon dioxide
