What else can I help you with?
When baking biscuits and other quick breads the baking powder reacts to release carbon dioxide bubbles the carbon dioxide bubble causes the dough to rise is this a physical or chemical change and why?
The reaction of baking powder to release carbon dioxide bubbles is a chemical change because it involves the formation of new substances (carbon dioxide gas) due to a chemical reaction. The carbon dioxide bubbles cause the dough to rise through physical expansion, but the underlying process of gas production is a chemical change.
Why does boiling remove carbon dioxide from antacid mixture?
Boiling removes carbon dioxide from an antacid mixture because carbon dioxide is a gas that can escape when heated. When the mixture is boiled, the carbon dioxide bubbles out of the solution, which reduces the effectiveness of the antacid in neutralizing stomach acid.
Why do the bubbles in Guiness descend instead of rising to the surface like normal bubbles?
Guiness does not have a higher tolerance to gravity as the other carbon dioxide fart. Gravity pushes the titles
How do animals depend upon plants?
Animals depend upon plants to produce oxygen (photosynthesis), to absorb carbon dioxide (plant respiration), and as a food source. Even animals that eat other animals (carnivores) depend on plants as a food source, as that is likely what their prey eat to survive.
What does a plant do to survive?
Green plants survive by taking in carbon dioxide, nutrients and water, and using sunlight to make carbohydrates and other complex molecules.
Does the body need carbon dioxide to survive and give off oxygen as a waste product?
no... it is the other way around
Why is carbon dioxide useful?
yes. plants breath in carbon dioxide and then breath out oxygen for other living creatures. then we breath in that oxygen and breath out more carbon dioxide for the plants. basically, we could not survive without plants.
How does a lily obtain oxygen?
They don't use oxygen they use carbon dioxide. They use the carbon dioxide that we breeth out and then they breeth out oxygen which we need to survive; that's why we need to keep planting trees and other plants!

Why do you see bubbles coming out when you open a Pepsi can?
The fluid is saturated or close to saturation with CO2 at the pressure in the bottle before opening, but supersaturated at atmospheric pressure. Bubbles will form (nucleation) on any floating solids or surfaces allowing the CO2 to approach saturation at atmospheric pressure.
Why soda fizzez?
The reason why soda, and other fizzy drinks have bubbles and 'fizz,' is because of carbonation. Carbonation is the process of dissolving carbon dioxide in water. The process usually involves carbon dioxide under high pressure. When the pressure is reduced, the carbon dioxide is released from the solution as small bubbles, which cause the solution to "fizz." This effect is seen in carbonated soft drinks. However, once the carbon dioxide is exposed to oxygen for extended periods of time, the pressure is gradually released and after time, the beverage will become flat, aka, losing its carbonation, or fizz.
What are The bubbles in fermented products?
The bubbles are carbon dioxide gas. In ethanol fermentation, that is fermentation of wine, beer or other hardy spirits, the equation works as such: C6H12O6 → 2 C2H5OH + 2 CO2 or Glucose → 2 Ethanol + 2 Carbon dioxide Another possibility is the production of hydrogen gas in butyric acid fermentation. That would be the fermentation of cheese.
