If the reaction N2 + 3 H2 → 2 NH3 is carried out using 1.40 g of N2 and 0.468 g of H2, what mass of excess reactant will remain?

For the reaction represented by the equation C12+ 2KBr      2KC1+Br2, how many grams of potassium chloride (KC1) are produced from 3.75 x 1023 molecules of chlorine gas (C12)?

A student performed a similar experiment to the one you performed: They took a crucible and lid, cleaned them, heated them over a flame, and after cooling found their combined mass to be 22.538 g. The student then added a sample of zinc(II) sulfate hydrate (ZnSO4·“n”H2O) to the crucible so the combined mass of the sample, crucible, and lid was 25.896 g. They heated this sample for 10 minutes with the lid ajar, let it cool, and measured the mass of the crucible, sample, and lid to be 25.054 g. a. Based on this experiment, what is the formula for they hydrated zinc(II) sulfate compound? b. The student later looked on the reagent bottle for zinc(II) sulfate hydrate and found the actual formula was ZnSO4·7H2O. If everything had been done correctly, what value should the student have expected for the final mass of their sample, crucible, and lid after heating?

If 9.9 × 10²⁵ molecules of CO₂ are produced in a combustion reaction, what is the mass in kg of CO₂ that is produced?

For the reaction represented by the equation CI2+2KBr   2KCI+ Br2, how many grams of potassium chloride (KCI) are produced from 9.2 x 1025 molecules of chlorine gas (CI2)?

d Iron metal reacts with chlorine gas giving iron (III) chloride. The balanced chemical equation for this reaction is: 2 Fe(s) + 3 Cl₂ (g) → 2 FeCl3 (s) If 32.0 g each of iron and chlorine are combined, what is the theoretical yield of iron (III) chloride? 9 Submit

Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid fuel rocket motors. The reaction is Fe2O3(s) + 2Al(s) → 2Fe(l) + Al2O3(s) Click here to see the reaction. What is the maximum mass of aluminum oxide that could be produced along with 81.59 g iron?

Consider the reaction of solid P₄ and chlorine gas to form gaseous phosphorus trichloride. The balanced chemical equation is P₄(s) + 6 Cl₂(g) → 4 PCl₃(g). How many grams of phosphorus trichloride can be formed from 419.7 grams of P₄ based on the balanced chemical equation?
