Answer:
The oxygen will appear in the final stage if the oxygen is excess from the beginning.
Explanation:
1. C +(1/2)O2 —> CO
2. CO+(1/2)O2—> CO2
The first stage explains that the oxygen is limited and hence CO is produced.
The 2nd stage explains that if the oxygen is excess, then CO2 will be produced.
The overall reaction when oxygen is excess is given by:
C + O2 —> CO2
I’m not sure what kind of answer you’re looking for, but if you’re supposed to translate it into a sentence it would be two moles of sodium bicarbonate(baking soda) decompose unto one mole of sodium carbonate(soda ash) plus one mole of water and one mole of carbon monoxide gas
The experiment is related to the demonstration using Pepper. When pepper is spread over water, it clumps together This is because pepper is hydrophobic. When repeated with sugar and salt, they instantly dissolved. This means they are attracted to water. When also sprinkled on the surface of the water, it floats. This is caused by surface tension.
To break the surface tension of water, one can use aeration or the use of chemicals such as soap molecules which contain a long chain of hydrogen as well as carbon atoms.
<h3>What is surface tension?</h3>
Surface tension is the propensity of liquid surfaces at rest to shrink to the smallest feasible surface area. Surface tension permits items with a higher density than water, such as razor blades and insects (such as water striders), to float on the water's surface without being immersed.
A force tensiometer can be used to measure surface tension. The forces exerted on a probe situated at the liquid-gas or liquid-liquid interface are measured by these devices.
