7.0 moles of sulfur atoms and 10 moles of oxygen molecules are combined to form the maximum amount of sulfur trioxide, how many moles of which reactant remain unused at the end of the reaction?
.........And oxygen is in deficiency. Given $10$ $mol$ of dioxygen gas, at most, $6.67$ $mol$ of sulfur trioxide can be generated. This is clearly indicated by the stoichometric equation. Should...

How many moles of zinc oxide is produced if 4.44 moles of zinc reacts with excess oxygen?
As for all these problems, we first need a stoichiometrically balanced equation, $Zn(s) + 1/2O_2(g) rarr ZnO(s)$ And thus between the oxide and the starting metal, there is clearly $1:1$...

How many moles of oxygen gas are produced when 0.500 mol $Na_2O_2$ reacts with water?
Sodium peroxide can be thermolyzed to give dioxygen gas... $Na_2O_2(s) +Delta rarr Na_2O(s) + 1/2O_2(g)uarr$ But with water, we simply get an acid base reaction.... $Na_2O_2(s) +2H_2O(l) rarr 2NaOH(aq) +...

Arsenic reacts with chlorine to form a chloride. If 1.587 g of arsenic reacts with 3.755 g of chlorine what is the empirical formula of the chloride?
$"Moles of arsenic"$ $=$ $(1.587*g)/(74.92*g*mol^-1)=0.0212*mol$. $"Moles of chlorine"$ $=$ $(3.755*g)/(35.45*g*mol^-1)=0.106*mol$. We divide thru by the lowest molar quantity to give $AsCl_5$. This is not chemical you would find in a...

Zinc oxide reacts with hydrochloric acid to produce zinc chloride and dihydrogen monoxide. If 3.6 moles of zinc oxide reacts with an excess of hydrochloric acid, then how many grams of zinc chloride were produced?
The reaction happening in solution is the following: $ZnO(aq)+2HCl(aq)->ZnCl_2(aq)+H_2O(l)$ Since the hydrochloric acid ($HCl$) is in excess, therefore, the number of moles of Zinc oxide ($ZnO$) will determine the mass...

Under certain conditions of temperature and pressure, hydrogen gas and nitrogen gas react to form ammonia gas. Determine the mass of ammonia produced if 3.50 moles of hydrogen has reacts with 5.00 moles of nitrogen gas?
Start 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...

According to the following reaction, how many moles of sulfur trioxide will be formed upon the complete reaction of 0.971 moles of sulfur dioxide with excess oxygen gas? sulfer dioxide (g) + oxygen (g) $->$ sulfer trioxide
We need a stoichiometic equation: $SO_2(g) + 1/2O_2(g) rarr SO_3(g)$ The equation unequivocally tells us that the reaction of $64*g$ $SO_2(g)$ with $16*g$ $O_2(g)$ gives $80*g$ $SO_3(g)$. The given masses...

What is the limiting reagent and the moles of $CO_2$ formed when 11 moles $CS_2$ reacts with 18 moles $O_2$ to produce $CO_2$ gas and $SO_2$ gas at STP?
Limiting reagent problems are all about using the that exists between the reactants to determine if you have enough of each reactant to allow for their complete consumption....

Propane, $C_3H_8$, reacts with oxygen to produce carbon dioxide and water. If 10.0 grams of oxygen reacts with an excess of propane, then how many moles of carbon dioxide were produced?
Given: Mass of $"O"_2$; chemical equation (understood) Find: Moles of $"CO"_2$ Strategy: The central part of any problem is to convert moles of something to moles of something else....

If iron (II) oxide gas decomposes into iron liquid and oxygen gas and 6 moles of iron (II) oxide gas are used, how of liters of oxygen gas are produced?
This means that for $6mol$ of $FeO$, only $3mol O_2$ is produced (half the moles). The volume of the oxygen is dependant on temperature and pressure. E.g. : If...
