Is the formation of zinc chloride from its constituent elements an example of a redox reaction....?
The given reaction is certainly a redox reaction. The metal, as is typical, is oxidized, $Zn(0)rarrZn(+II)$, and the non-metal is reduced, $Cl_2(0)rarrCl(-I)$,. Generation of $"ferric chloride"$ represents another redox equation:...

How do we represent the combustion of hexanes? And how do we represent the formation of silver chloride from sodium chloride, and silver nitrate?
So, you have to balance 2 unspecified equations. I'll give you 2, which might or not be suitable. Firstly, combustion of hexane (the which drives your motor!): $C_6H_14(g) + 19/2O_2(g)...

With respect to the following reaction, which is the correct statement?
$2HNO_3(aq) + 3H_2S(aq) rarr 3S(s)+2NO(g) +4H_2O$; a. both sulfur and nitrogen are reduced; b. nitrogen is reduced and sulfur is oxidized; c. oxygen is oxidized; d. this is not redox.
$2HNO_3 + 3H_2S rarr 3Sdarr +2NOuarr +4H_2O$ Can you write the redox half equations? Nitrate ion, $N(+V)$, is reduced to nitrous oxide, $N(+II)$. $HNO_3 + 3H^(+) +3e^(-) rarr NO +...

What coefficient is placed in front of $O_2$ to complete the balancing of the following equation $C_5H_8 + ?O_2 -> 5CO_2 + 4H_2O$?
You're off to a nice start. The balanced form of the chemical equation you have provided is: $C_5H_8+7O_2->5CO_2+4H_2O$

What balanced equation represents a redox reaction?
The key to identifying oxidation-reduction reactions is recognizing when a chemical reaction leads to a change in the oxidation number of one or more atoms. You have probably learned the...

Permanganate ion is reduced to $MnO_2$, and ammonia is oxidized to nitrate ion. Can you write a balanced chemical equation to represent the redox process?
You really have to make a meal out of these redox equations. Permanganate ion (STRONGLY COLOURED PURPLE) could be reduced to almost colourless $Mn^(2+)$.... $stackrel(+VII)[MnO_4]^(-) +8H^(+) + 5e^(-) rarr Mn^(2+)...

How do we represent the formation of $FeS$ by the redox reaction of iron and sulfur?
And thus, when zerovalent, i.e. elemental, iron is oxidized, we represent the oxidation on these terms: $Fe rarr Fe^(2+) + 2e^-$ $(i)$ On the other hand, $"reduction is the formal...

What mass of $"potassium chloride"$ would result from the redox reaction of $"potassium chlorate"$? How is the reaction represented stoichiometrically?
Often a little $"manganese(IV) oxide"$ is added to these reactions, as an oxygen transfer reagent, i.e. a catalyst. Given the , moles of $"potassium chloride"$ produced are CLEARLY equal...

C3H8(g)+5O2(g)→ 3CO2(g)+4H2O(l)
(a) In the complete combustion of propane, how many moles of CO2(g) are produced per mole of O2(g)?
(b) In the complete combustion of propane, how many moles of H2O(l) are produced per mole of O2(g)?
a) Using the mole ratio from the equation, $5$ mols of $"O"_2$ will produce $3$ mols of $"CO"_2$. Therefore, the ratio of $"O"_2$ used to $"CO"_2$ produced will be $1:3/5$....

In a combustion reaction, initially there were $77.8*g$ of oxygen gas, and a $22.8*g$ mass of carbon; $18.0*g$ of oxygen remained after the reaction. If the carbon were completely oxidized, what mass of carbon dioxide resulted?
$77.8*g-18.0*g$ oxygen gas reacted, and $22.8*g$ carbon was consumed. Given complete combustion, CLEARLY, $(59.8+22.8)*g=82.6*g$ $CO_2(g)$ were produced. Why $"CLEARLY?"$. Because mass is conserved in all chemical reactions. $"Garbage in must...
