How well would you expect a microwave oven to heat liquid carbon dioxide?
I don't believe carbon dioxide has a liquid phase! It exists only as a solid (dry ice) and as a gas. Therefore it would be impossible to heat liquid carbon dioxide.
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 do scientists expect to happen to the climate of the earth if the 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 might you expect silicon dioxide and carbon dioxide to have similar melting and boling points?
You Ultimately would not expect them to have similar melting and boiling points.This is because Carbon Dioxide is a gas, it might have strong covalent bonds between their atoms but between their molecules they have weak intermolecular forces, therefore these forces are easily overcome during heating in lower temperaturesHowever when you look at Silicon Dioxide, it has a macromolecular structure. In other words the whole solid is actually just one molecule which its atoms are each covalently bonded to each other. Therefore since it has strong covalent bonds between them you would expect them to have extremely high melting and boiling points.Diamond is a macromolecular structure and it has a melting point of 3006 degrees centigrade. You could expect Silicon Dioxide's melting point (and boiling point) to be similarly high.
What effect does changing temperature and pressure have on the rate that carbon dioxide gas comes out of a soda bottle?
Higher temperature will cause the carbonation to escape faster, if the soda is opened. If the soda is not opened, temperature will have no effect but to increase the pressure inside of the container.

What substance would the student expect to find if respiration occurred in the test tube?
Carbon Dioxide (CO2)
Would you expect that the concentration of carbon dioxide over an industrial site will be higher or lower?
The concentration of carbon dioxide over an industrial site might be higher, because of the emissions, however, carbon dioxide mixes well with other gases, so it will spread out all over the world.
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?
I expect you are asking what happens if carbon dioxide is bubbled through limewater. The limewater will become cloudy.

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.
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.
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 non-human activity produces carbon like plants etc?
Carbon is produced in the form of carbon dioxide as a by product ( waste product) of respiration. People commonly think that only animals respire. This is not true. Both plants and animals respire but plants do this only at night and animals/humans do this constantly to stay alive. so plants produce carbon in the form of carbon dioxide other animals do via respiration also, combustion produces Co2 aswell as this which is an identical process to aerobic ( with oxygen) respiration except it produces smoke aswell as carbon dioxide and other chemicals depending on what you are burning. Fermentation so making beer involves a different type of respiration which forms carbon dioxide known as anaerobic respiration ( without oxygen) glucose->CO2 and ethanol ( alcohol) carbon itself can be found in what you'd least expect . . . diamond and other substances such as graphite which are formed deep underground due to the temperature and pressure. hope this helps
