$4NH_3(g) + 5O_2(g) rarr 4NO(g) + 6H_2O(g)$ Is this balanced? Can you write redox half equations? What is the oxidation state of $N$ in nitrous oxide? What is species is...
1 Answers 1 viewsThe first thing to do here is identify your reactants and your product. The problem tells you that gaseous nitrogen dioxide, $"NO"_2$ reacts with gaseous oxygen, $"O"_2$, and liquid...
1 Answers 1 viewsThis is a synthesis reaction, also called a combination reaction, because two or more reactants produce a single product. You essentially have been given a word equation, which does not...
1 Answers 1 viewsYou can double the equation if you like; either equation shows that 1 equiv of ethane reacts with 7/2 equiv dioxygen gas to give 2 equiv carbon dioxide and 3...
1 Answers 1 viewsThe stoichiometrically balanced equation tells us unequivocally that $1$ $mol$ dihydrogen reacts with $0.50$ $mol$ dioxygen to give $1$ $mol$ water. $"Moles of dihydrogen"$ $=$ $(58.1*g)/(2.02*g*mol)$ $=$ $28.7*mol$ $H_2$ $"Moles...
1 Answers 1 views$"Moles of ferric oxide "=(0.18*g)/(159.69*g*mol^-1)$ $=$ $1.13xx10^-3*mol" metal oxide"$. $"Moles of carbon monoxide "=(0.11*g)/(28.0*g*mol^-1)$ $=$ $3.93xx10^-3*mol" CO"$. $Fe_2O_3$ is the reagent in deficiency (why?), and thus $2xx1.13xx10^-3*molxx55.85*g*mol^-1~=0.150*g$ iron metal are...
1 Answers 1 viewsStart by balancing the equation for the reaction between hydrogen $"H"_2$ and nitrogen $"N"_2$, which produces ammonia $"NH"_3$: $color(darkgreen)(1) color(white)(.) "N"_2 (g) + color(darkgreen)(3) color(white)(.) "H"_2 to color(darkgreen)(2) color(white)(.) "NH"_3...
1 Answers 1 viewsThe chemical formula for ammonia is $2NH_3$ meaning that we have two nitrogen atoms and six hydrogen atoms. To find the ratio of nitrogen atoms to hydrogen atoms...
1 Answers 1 viewsGiven stoichiometric oxygen, ammonia gives an equimolar quantity of $NO$. $"Moles of ammonia"$ $=$ $(17.0*g)/(17.03*g)$ $~=$ $1*mol$ $"Moles of dioxygen"$ $=$ $(16.0*g)/(32.03*g)$ $~=$ $0.50*mol$ Clearly, dioxygen is in deficiency,...
1 Answers 1 viewsIn acting as an electron pair donor, the nitrogen has become quaternized, and has demonstrably increased hydroxide ion concentration. It has therefore acted as a base by several definitions.
