What else can I help you with?
What would happen to the rate of photosynthesis if the concentration of carbon dioxide decreased?
Rate is often proportional to the concentration of the reactants. If the carbon dioxide were less concentrated we should expect the rate to decrease, other factors being equal.
What substance would the student expect to find if respiration occurred in the test tube?
The student would expect to find carbon dioxide in the test tube, as it is a product of cellular respiration.
Does carbon dioxide react with iodine solution?
I'd say NO: I never would expect it, nor having heard of and can't think why it could be yes.
Does carbonation have an affect on the growth of plants?
Generally, yes. Plants "breathe in" carbon dioxide and "breathe out" oxygen. Carbonation in water is suffused carbon dioxide, so we would expect that the extra CO2 would promote plant growth.
What happens to the limewater if the gas is present?
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
How well would you expect a microwave oven to heat liquid carbon dioxide?
A microwave oven would not heat liquid carbon dioxide effectively because carbon dioxide is not a good absorber of microwave radiation due to its non-polar nature. Microwaves work best on polar molecules like water that can absorb and convert the microwave energy into heat efficiently.
If carbon dioxide is completely removed from a plants environment what would you expect to happend to the plants production of high energy sugars?
It would remain the same.
Do you expect yeast to produce a gas when sugar is available?
Yes, in the presence of sugar, yeast ferments releasing carbon dioxide (which makes the bubbles in bread dough).
What do scientists expect to happen to the climate of the earth if carbon dioxide levels continues to rise?
The climate will become very unusually and we will have stormy climates. It will also be warm at times.
Why would you expect to find carbon dioxide in your breath?
we breathe out oxygen, nitrogen, and carbon dioxide, same components as the air we breathe in,Read more: What_do_you_breath_out_as_well_as_carbon_dioxide
How does co2 cause global warming?
Fossil fuels, such as gasoline, methane, and propane, contain carbon. When fossil fuels are burned they react with oxygen to produce carbon dioxide. Due to the increase in consumption of fossil fuels, the amount of carbon dioxide in the air is increasing. Carbon dioxide in the atmosphere lets light energy in, but less heat energy out, thus producing a 'greenhouse effect'.
What do scientists expect to happen to the climate of the earth if the carbon dioxide levels continues to rise?
Scientists expect that if carbon dioxide levels continue to rise, it will lead to an increase in global temperatures, resulting in more frequent and severe heatwaves, wildfires, droughts, and extreme weather events. This can also lead to rising sea levels, loss of biodiversity, and disruptions to ecosystems and agriculture.
