The material, Brass is not an element. The different elements can be seen on the periodic table. Anyway, brass is an alloy of metal. Although, gold, silver, copper and many others are elements. Hope i helped. Have a nice day.

Answer:
the conversion factor is f= 6 mol of glucose/ mol of CO2
Explanation:
First we need to balance the equation:
C6H12O6(s) + O2(g) → CO2(g) + H2O(l) (unbalanced)
C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) (balanced)
the conversion factor that allows to calculate the number of moles of CO2 based on moles of glucose is:
f = stoichiometric coefficient of CO2 in balanced reaction / stoichiometric coefficient of glucose in balanced reaction
f = 6 moles of CO2 / 1 mol of glucose = 6 mol of glucose/ mol of CO2
f = 6 mol of CO2/ mol of glucose
for example, for 2 moles of glucose the number of moles of CO2 produced are
n CO2 = f * n gluc = 6 moles of CO2/mol of glucose * 2 moles of glucose= 12 moles of CO2
- P2H2 Oxidation State - Diphosphene
P2H2 has an oxidation number of +1. In P2H2, the oxidation
number of H is -1
- H2C2O4 Oxidation State - Oxalic Acid
C has an oxidation number of +3 in H2C2O4. O has an oxidation
number of -2 in H2C2O4. H2C2O4 has an oxidation number of +1.
- CrO2 Oxidation State - Chromium(IV) Oxide
CrO2 has an oxidation number of +4.
<h3>Explain oxidation?</h3>
The oxidation state, also known as the oxidation number, is an atom's hypothetical charge if all of its bonds to other atoms were fully ionic.
The sum of the oxidation states of all the atoms in an ion equals the ion's charge.
A substance's more electronegative element is given a negative oxidation state. The one that is less electronegative is given a positive oxidation state.

The barometer would show a decrease in wind speed resulting in the disipation of cloud cover because of the lack of wind, and also because the temperature is dropping there is less precipation because there is no hot air rising to create clouds :)
