Molar mass of CO2; is 44.01 g/mol and molar mass of C6H12O6 is 180.2 g/mol
a. Balance the equation: C8H18(l) + O2 (g) ---> CO2(g) + H2O(g) (NOT balanced)
b. Balance the equation: CO2(g) + H2O(l) ----> O2(g) + C6H12O2(aq) (NOT balanced)

Stoichiometry using co2 and glucose
Burning of fossil fuel (equation a), gasoline, produces carbon dioxide CO₂, one of the global warming contributors. But carbon dioxide plays an important role in photosynthesis which reacts with water in the presence of sunlight and produces glucose and oxygen gas according to the equation below (equation b). Excessive logging in the rain forest is another global warming contributor.
Molar mass of CO₂ is ...
It calculates the amount of glucose produced by small patch of trees. Furthermore, it calcualtes the oxygen gas produced from CO2, which is byproduct of the first reaction. The solution is detailed and has a '5/5' rating.
Cellular respiration and photosynthesis, prokaryotic and eukaryotic cells, and simple hypothesis
1. Create a table comparing and contrasting the two processes. Include in your comparison variables such as organism type, energy source, cellular location, substrates/reactants/products, full and balanced chemical reaction, carrier molecules, and any other parameter you find relevant.
2. Apart from its essential role in cellular respiration, the mitochondrion is thought to be implicated in a variety of disease states as well as the process of aging. The mitochondrion contains its own circular DNA molecule(s) (termed mtDNA) which largely encodes for proteins localized to the mitochondrion itself.
3. Please provide a hypothesis and suggest an experiment to test the relationship between mtDNA and human aging.
4. Propose a direction for future research and drug development for targeting mtDNA to combat the ageing process.
Identify and describe one or two structural and functional differences between prokaryotic and eukaryotic cells that you believe contribute to the ability of eukaryotic cells to form the specialized cells and structures found in multicellular organisms.
While there are several differences between prokaryotic and eukaryotic cells,
Please limit your answer to those structural and functional differences that will assist in the evolution of multicellularity.
Choose two organisms that interact with each other, such as bees and flowers, or consider the effect of any environmental factor on an organism, such as light, sound, air quality, food preference, or nutrient quantity or quality .
Now form a simple hypothesis about this interaction.
Include the observation that led you to a hypothesis . Use the scientific method and your imagination to design an experiment that you might do to test this hypothesis.
Be sure to include controls, and describe the variables that would remain constant and the one that you want to test.
(Remember, you can only test one variable at a time.) Describe the type of data you would collect, and how you would evaluate it. What are your expected results (predictions)?
State what your conclusion would be depending on those results. Would these results lead you to accept or reject your hypothesis?
Your format should then look like this:
Introduction: Describe your observation. Include any background information you may have found.
Hypothesis: Write a statement that describes your explanation for the observation.
Methods: Describe the experiment, variables to be held constant, variable to be tested, and controls.
Predictions: What do you predict as outcomes (results) of this experiment?
Conclusions: Do you accept or reject or accept hypothesis? Explain why.
Remember, you don't have to actually do the experiment, just write what you would do to test your idea
