What else can I help you with?
How could you use a wooden splint and a flame to identify each of these gases?
To identify gases using a wooden splint and a flame, you can perform two tests: For hydrogen, introduce a lit wooden splint to the gas; if it produces a characteristic "pop" sound, hydrogen is present. For oxygen, place a glowing (but not burning) wooden splint into the gas; if it reignites, oxygen is confirmed. For carbon dioxide, passing the gas over a glowing splint will extinguish it, indicating the presence of carbon dioxide.
What chemical test would you carry out to prove that the figures of carbon dioxide in air are accurate?
To prove the accuracy of the carbon dioxide figures in air, you can perform a chemical test using a carbon dioxide gas sensor or a colorimetric method such as using pH indicators like bromothymol blue. These tests can help you quantify the levels of carbon dioxide present and confirm the accuracy of the measurements.
How can you test carbon dioxide?
One common way to test for carbon dioxide is to bubble the gas through limewater (calcium hydroxide solution). When carbon dioxide reacts with limewater, it forms a white precipitate of calcium carbonate. Additionally, carbon dioxide can be tested using pH indicators like bromothymol blue, which changes color in the presence of carbonic acid formed when carbon dioxide dissolves in water.
Is plants using carbon dioxide and water to form oxygen and sugar a chemical or physical change?
Physical changes
Do chemical reactions always make new substances?
No all chemical reactions do not make new things because if you do a chemical reactions using two of the same things e.g carbon dioxide + carbon dioxide you are not making anything else so no not all chemical reacions make new things
What of these will show that a gas is carbon dioxide?
The gas can be identified as carbon dioxide using a limewater test, where the gas is bubbled through limewater causing it to turn cloudy. Additionally, a carbon dioxide gas sensor can detect the presence of carbon dioxide in the air. Chemical tests such as reacting the gas with sodium hydroxide can also confirm the presence of carbon dioxide.

Is carbon dioxide an example of a chemical name using prefixes?
yes
Is Photosynthesis a chemical?
photosynthesis is not a chemical but a process that plants use to make glucose using the sun, carbon dioxide and water

What happens when acid react with compounds made of carbonate?
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!
What mass of carbon monoxide must react with oxygen to produce 0.69g of carbon dioxide?
To find the mass of carbon monoxide needed, first convert the mass of carbon dioxide to moles using its molar mass. Then, use the balanced chemical equation for the combustion of carbon monoxide to determine the mole ratio between carbon monoxide and carbon dioxide. Finally, convert the moles of carbon dioxide to mass of carbon monoxide using its molar mass.
Is plants using carbon dioxide and water to form oxygen and sugar a chemical or physical change?
Physical changes
Organism that makes organic carbon molecules from carbon dioxide using energy from chemical reactions?
Autotrophic plants. You've described photosynthesis, basically.
What is the production of chemical energy by green plant using carbon dioxide water and radiant energy from the sun?
Photosynthesis is the production of chemical energy by plants.
What does photosynthnesis mean?
Is a chemical process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight.
