How many moles of magnesium chloride (MgCl2) are present in 27.13g of magnesium chloride?

An explosive reaction between butane and oxygen occurs as follows. 2 C4H10 (g) + 13 O2 (g) -->  8 CO2 (g) + 10 H2O (g) If 0.625 moles of butane and 3.5 moles of oxygen gas react predict the theoretical yield (in moles) of water vapor that would be produced.

How many grams of Cr are produced ( assuming 100% yield) when 68.1g of AL reacts with 364 g of Cr2O3.

22.0 g of CO​​2 gas and 9.01 g of H​​2O gas are formed from combustion of an unknown hydrocarbon (containing only hydrogen and carbon) in the presence of O​​2 gas. The molar mass of the gas is 84.2 g/mol. What is its molecular formula?

Aqueous hydrochloric acid  HCl  reacts with solid sodium hydroxide  NaOH  to produce aqueous sodium chloride  NaCl  and liquid water  H2O . If  0.226g  of sodium chloride is produced from the reaction of  0.73g  of hydrochloric acid and  0.43g  of sodium hydroxide, calculate the percent yield of sodium chloride.

[References] Ammonia gas can be prepared by the reaction of a metal oxide such as calcium oxide with ammonium chloride. CaO(s) + 2 NH, Cl(s) → 2 NH3 (g) + H. O(g) + CaCl, (s) If 102 g of CaO and 241g of NH, Cl are mixed, what is the limiting reactant, and what mass of NH3 can be produced? The limiting reactant is CaO Mass of NH3 = 6. Drag and drop your selection from the following list to complete the answer: NH3 NH, C1 CaCl, 23

Aluminum reacts with bromine, producing aluminum bromide:                 2A1(s) + 3Br2(1) → 2A1Br3(s) In a certain experiment.20.0mL of bromine(density3.10g/mL) was reacted with excess aluminum to yield 50.3g of aluminum bromide. What is the percent yield for this experiment?

If 7.700000000000000 × 10²⁵ molecules of CO₂ are produced in a combustion reaction, how many liters of CO₂ is produced? (The density of CO₂ is 1.98 kg/m³ and 1 L = 1 dm³).

Given the following decomposition reaction: 4C3H5O9N3  → O2 + 12CO2 + 10H2O +6N2. a. If 28.40 g H2O were produced, what mass of CO2 will be produced?  b. If 110.5 g of C3H5O9N3 were decomposed and the yield of the reaction is 72.3%, determine the theoretical yield and actual yield.
