Answer:
6CO2 + 6H2O --> C6H12O6 + 6O2
C6H12O6 + O2 --> 6CO2 + 6H2O
Explanation:
The balanced form of both equations
Carbon has an outer shell consisting of 4 valence electrons. ... Thus, a carbon ion can have a charge of anywhere from -4 to +4, depending on if it loses or gains electrons. Although the most common oxidation states of carbon are +4 and +2, carbon is able to make ions with oxidation states of +3, +1, -1, -2, and -3.

Answer:
34.44 g.
Explanation:
- The balanced equation for the reaction is:
<em>Fe + S → FeS,</em>
<em></em>
<em>It is clear that 1.0 mol of Fe reacts with 1.0 mol of S to produce 1.0 mol FeS.</em>
<em />
- We need to calculate the no. of moles of 60 grams of iron and 90 grams of iron sulfide:
no. of moles of Fe = mass/atomic mass = (60.0 g)/(55.845 g/mol) = <em>1.074 mol.</em>
<em>no. of moles of FeS = mass/molar mass</em> = (90.0 g)/(87.91 g/mol) = <em>1.024 mol.</em>
<u><em>∵ Fe reacts with S with (1: 1) molar ratio.</em></u>
∴ The no. of moles of S needed to react with Fe is 1.074 mol.
<em>∴ The no. of grams of S needed = no. of moles x molar mass </em>= (1.074 mol)(32.065 g/mol) = <em>34.44 g.</em>
we are given the reaction Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag. This means for every mole Cu used, there are 2 moles of Ag produced. In this case, given 31.75 g Cu, converting to moles through molar mass and using stoichiometric ratio and the molar mass of Ag, the mass Ag produced is 107.9 grams.
