Describe, using scientific terms, how plants turn sunlight into energy? make sure to refer to the chemical equation to photosynt
Sergio039 [100]
A plant is a living organism that uses chlorophyll in the chloroplasts to perform photosynthesis. The chemical equation of photosynthesis is
Sunlight(Photons)+ CO2+2H2O ----->C6H12O6+H2O+O2.(Not balanced) The reactants are carbon dioxide and water. The products are water and glucose with oxygen as a waste product.Photosynthesis can make a plant form a closed cycle as plants need to respire with oxygen which is a waste product of one of their reactions.

Rusting of iron is a very common chemical reaction. It results in one form from Fe reacting with oxygen gas to produce iron (III
Vlada [557]

<u>Answer:</u> The given amount of iron reacts with 9.0 moles of O_2 and produce 6.0 moles of Fe_2O_3

<u>Explanation:</u>

We are given:

Moles of iron = 12.0 moles

The chemical equation for the rusting of iron follows:

4Fe+3O_2\rightarrow 2Fe_2O_3

  • <u>For oxygen gas:</u>

By Stoichiometry of the reaction:

4 moles of iron reacts with 3 moles of oxygen gas

So, 12.0 moles of iron will react with = \frac{3}{4}\times 12.0=9.0mol of oxygen gas

  • <u>For iron (III) oxide:</u>

By Stoichiometry of the reaction:

4 moles of iron produces 2 moles of iron (III) oxide

So, 12.0 moles of iron will produce = \frac{2}{4}\times 12.0=6.0mol of iron (III) oxide

Hence, the given amount of iron reacts with 9.0 moles of O_2 and produce 6.0 moles of Fe_2O_3

Select the solute that is likely most soluble in hexane, C6H14-​
Bad White [126]

Answer:

The solute that is most likely soluble in hexane is S₈

Explanation:

S₈ is a non-polar solute that exhibits the same characteristics and properties as hexane. Following the common principle "like dissolves like"; polar compounds will be soluble in polar solvents while non-polar compounds will be soluble in non-polar solvents. As such, since S₈ is non-polar, then it will be soluble in hexane.
