What gas is likely to be in photosynthesis give off?
Oxygen is given off as a by-product os photosynthesis
What instrument measures the amount of gas given off by yeast?

An indegestion powder contains sodium hydrogencarbonate and a small amount of citric acid. the powder starts to fizz when it is added to water. what gas is given off when the mixture fizzes?
carbon dioxide
What is given off when a sweet fizzes?
CO2. Under pressure you get carbonic acid (H2CO3) which spontaneously breaks up into CO2 and water.
What gas would be given off if graphite hydrochloric were mixed?
None, no gas is given off.
When you burn Super Glue what toxic gas is given off?

What is the diffrence between inference and observation?
An observation is what you actually see happening. An inference is the conclusions you draw from that observation. To use an analogy; You may be doing a chemistry experiment and when you put two substances together, the mixture bubbles and brown gas comes off. You know that brown gas indicates nitrogen dioxide gas. The observation would be "Mixture bubbles and brown gas is given off" The inference would be "A gas is produced, nitrogen dioxide"
