What else can I help you with?
What does light energy do to water and carbon dioxide?
Light has little or no effect on water and carbon dioxide, unless a catalyst such as chlorophyll is present. In that case, the light energy is absorbed and the water and carbon dioxide are converted to glucose and water. This is photosynthesis.
What substance used to detect the presence of carbon dioxide?
Test for Carbon Dioxide: Bubble unknown gas in lime water. Limewater should go milky if Carbon dioxide is present. Test for water: Add anhydrous copper sulphate crystals (white in colour) to unknown solution. If solution goes a brilliant light blue colour, water is present as the hydrous copper sulphate crystals were formed. Did this help?
What are the raw materials required by the plants to prepare their food?
Sunlight (Trapped by the green pigment, chlorophyll present in the leaves), Water, Carbon Dioxide, Soil nutrients such as Nitrogen, Phosphorous, Potassium (collectively called NPK which is also a fertilizer).
What two things must be taken in by a plant for photosynthesis?
The two things that a plant takes in for photosynthesis are : light and carbon dioxide.
Is soda water a solution?
water is solvent and carbon dioxide is solute
What is the fizz in soda called?
Cardon Dioxide in the carbonated water that forms the base of any soda.
When do lime water turns chalky?
When carbon dioxide is passed through lime water, it forms calcium carbonate, which makes the solution turn chalky or cloudy. This reaction occurs as the carbon dioxide reacts with the calcium hydroxide in the lime water to form the insoluble calcium carbonate precipitate.
When lime water is added to gases the liquid turned chalky what is the name of this substance?
The substance that forms when lime water reacts with gases and turns chalky is calcium carbonate. This reaction occurs when carbon dioxide in the gas combines with the calcium hydroxide in the lime water to form calcium carbonate, which appears chalky.
Is there naturally sulfur dioxide in water?
No sulfur dioxide is not present naturally. It pollutes the water.
Are the fumes of Bi Carb mixed with vinegar harmful?
A mixture of sodium ethanoate, water and cardon dioxide is going to be produced. Carbon dioxide can be harmful so I'd recommend not inhaling the fumes produced
Why would chalky soil be a concern?
Chalky soil can present challenges for plant growth due to its high alkaline pH levels. This can result in nutrient deficiencies as certain plants may struggle to absorb essential nutrients. Additionally, chalky soil may have poor water retention capabilities, leading to drought stress in plants.
What four things does a flower need for photosynthesis?
A flower needs sunlight, water, carbon dioxide, and chlorophyll to carry out photosynthesis. Sunlight provides energy for the process, water is used in the reaction, carbon dioxide is absorbed from the air, and chlorophyll is the pigment that captures the light energy.
What are 4 small molecules that can move easily through the phospholipid bilayer?
i do not know all four, but i know three are: O2 (Oxygen) CO2 (Cardon Dioxide) and H2O (Water)
What is the function of lime water used in testing for carbon dioxide gas?
It is to make sure that carbon dioxide is present or not present in the experiment.
What turns milky when carbon dioxide is present?
lime water
Why does exhaled air turn limewater chalky faster than inhaled water?
carbon dioxide turns lime water chalky. the more carbon dioxide, the faster the limewater turns chalky. Exhaled air contains carbon dioxide waste from the bodies organs, and that's why it contains more carbon dioxide than inhaled air.
How would you test or carbon dioxide?
add lime water to the air if the lime water turns cloudy then carbon dioxide is present
