How can carbon cycle very quickly back into the enviornment

<span> The short term cycling of carbon begins with carbon dioxide (CO2) in the atmosphere. Through photosynthesis, the inorganic carbon in carbon dioxide plus water and energy from sunlight is transformed into organic carbon (food) with oxygen given off as a waste product.</span>

<h3>Answer: b) 0.250 mol</h3>

============================================

Work Shown:

Using the periodic table, we see that

1 mole of carbon = 12 grams
1 mole of oxygen = 16 grams

These are approximations and these values are often found underneath the atomic symbol. For example, the atomic weight listed under carbon is roughly 12.011 grams. I'm rounding to 2 sig figs in those numbers listed above.

So 1 mole of CO2 is approximately 12+2*16 = 44 grams. The 2 is there since we have 2 oxygens attached to the carbon atom.

-------------------

Since 1 mole of CO2 is 44 grams, we can use that to convert from grams to moles.

11.0 grams of CO2 = (11.0 grams)*(1 mol/44 g) = (11.0/44) mol = 0.250 mol of CO2

In short,

11.0 grams of CO2 = 0.250 mol of CO2

This is approximate.

We don't need to use any of the information in the table.

For the energy diagram of the chemical reaction depicted here, which statement is the best conclusion?

34kurt

The reaction shown here is an exothermic reaction.

<h3>What is an exothermic reaction?</h3>

An exothermic reaction is one in which the energy of the reactants is greater than the energy of the products. This implies that energy is given out in the process. Whether a reaction is endothermic or exothermic shows in the nature of the reaction profile curve.

For an endothermic reaction, the part of the diagram that represents the energy of the products is higher than the part that represents the energy of the reactants. This is clear from the image attached here.

If we look at the reaction graph very well, we will observe that the energy of the reactants is far above that of the products. Thus it follows that the reaction shown here is an exothermic reaction.
