How does phenolphthalein show carbon dioxide?
The solution of carbon dioxide in water is colorless.
Is carbon dioxide formed when acid reacts with base?
Carbon dioxide does not show reactions with acids.
How would you test that carbon dioxide is needed for photosynthesis?
To test if carbon dioxide is necessary for photosynthesis, you can conduct an experiment using two groups of plants: one group exposed to carbon dioxide and another group in an environment devoid of carbon dioxide. Monitor the plants for growth and the production of oxygen, which can be measured through the release of bubbles in water or using a dissolved oxygen meter. If the plants in the carbon dioxide-free environment show little to no growth or oxygen production compared to the control group, it would indicate that carbon dioxide is essential for photosynthesis.
Do chemical formulas show the total number of atoms in a sample of a compound?
Yes, chemical formulas show the number of atoms in a compound. Water is H2O -- two hydrogen atoms bonded to one oxygen atom. Carbon dioxide is CO2 -- one carbon and two oxygen atoms.
What jar contained carbon dioxide?
The jar that contained carbon dioxide was typically identified during experiments involving gas collection, such as those demonstrating the respiration of yeast or the reaction of vinegar and baking soda. In these experiments, carbon dioxide is produced as a byproduct and can be captured in a jar or container. Additionally, jars used in the study of photosynthesis may show a decrease in carbon dioxide levels when plants are involved. The specific jar would depend on the context of the experiment being conducted.
How does phenolphthalein show carbon dioxide?
The solution of carbon dioxide in water is colorless.
Is carbon dioxide formed when acid reacts with base?
Carbon dioxide does not show reactions with acids.
How do you show that propane contains hydrogen?
Propane is a hydrocarbon compound composed of carbon and hydrogen atoms. Its chemical formula is C3H8, indicating that it contains hydrogen atoms. The presence of hydrogen in propane can be confirmed through various analytical techniques such as elemental analysis or spectroscopic analysis.

What does 6co2 mean?
6CO2 represents six molecules of carbon dioxide. This formula is used to show the reactants in a chemical equation or reaction involving carbon dioxide.
How can you show that you breathe carbon dioxide?
By blowing into a test tube of bicarbonate of soda, this should turn cloudy if carbon dioxide is present
How can you show the effect of pressure on the solubility of carbon dioxide gas in water?
You can show the effect of pressure on the solubility of carbon dioxide gas in water by conducting an experiment where you change the pressure on a closed system containing carbon dioxide and water. By altering the pressure and observing how the solubility of carbon dioxide changes, you can demonstrate the relationship between pressure and solubility.
Changes in temperature and carbon dioxide level show a?
Correlation.
What could you use to show that carbon dioxide is give off when calcium carbonate is heated?
Carbon dioxide makes lime water milky.
What are the colors of hydrogen carbonate indicator?
The hydrogen carbonate indicator is used to test for carbon dioxide. If it stays in the normal air, it remains red. If there is more than 0.03 percent of carbon dioxide in the air, it would turn yellow. It there is less than 0.03 percent of carbon dioxide it would turn purple.
Do chemical formulas show the total number of atoms in a sample of a compound?
Yes, chemical formulas show the number of atoms in a compound. Water is H2O -- two hydrogen atoms bonded to one oxygen atom. Carbon dioxide is CO2 -- one carbon and two oxygen atoms.
What causes carbon dioxide to emit from the skin?
One of the causes of carbon dioxide emitted from the skin is sweating. Research studies show humans are more prone to release carbon dioxide from heavy breathing due to vigorous exercises.
