After adding aqueous sodium carbonate solution, the student obtains 0.875 g of Cuco, precipitate. A student dissolves 1.50 g of copper(II) nitrate in water. If 25.0 ml of C,H, reacts with 75.0 ml of O, what is the limiting reactant? Assuming constant conditions, what is the volume of Co, produced? 2 CH2(g) +5 0(g) = > 4CO2(g) + 2 H2O(g) 18. Air pressure inside the tube causes the mercury to move in the tube until the air. In oxyacetylene welding, acetylene reacts with oxygen to give carbon dioxide and water. Briefly describe two methods one might use to find the molar mass of a. bromide (NH 4 )Br Lithium carbonate Li2(CO3) Sodium sulfite Na 2 S Mercury(I) phosphite. An insulated box containing a monoatomic gas of molar mass M moving with a speed v. Naming Compounds & Writing Formulas & Calculating Molar Mass. The equation for the reaction is 3 MnO2(1 + 4 Al() 3 Mn() + 2 A1,0,(s) 17. Q.55 A gas is being collected in a beaker over mercury. Identify the limiting! reactant and calculate the mass of manganese metal produced. In a reaction, 50.0 g of manganese(IV) oxide reacts with 25.0 g of aluminum. Identify the limiting reactant, and calculate the moles of iron produced in the so- called Thermite reaction: 3 FeO() + 2 Al() - 3 Fe(1) + Al2O3(s) 16. A 1.00 mol sample of iron(II)oxide is heated with 1.00 mol of aluminum metal and converted to molten iron. Assume that all volumes of gas are measured under constant conditions of 500 *C and 300 atm pressure: N2(g) + 3 H2(g) → NH3(g) 15. If 5.55 L of nitrogen gas is available, calculate the volume of ammonia that is produced. In the Haber process, nitrogen and hydrogen gases combine to give ammonia gas. Molar Mass, Molecular Weight and Elemental Composition Calculator Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of mercury is 200. If an air bag contains 100.0 g of NaN (65.02 g/mol), what is the volume of nitrogen gas produced at STP? The equation for the reaction is 2 NaN,(s) - Na(s) + 3 N (9) 14. (a) Show that saturated mercury vapour should behave like a perfect classical gas under these conditions. The density of saturated mercury vapour at its normal boiling point at atmospheric pressure, 630 K, is p 3.87 kg/m3. In an automobile collision, sodium azide, NaN, decomposes and fills an air bag with nitrogen gas. The molar mass of mercury is 200.6 g/mole. XPS Scores 9 openmolecules Name: Mercury(II) Nitride 6882 Even better. Calculate the mass of mercury produced from the decomposition of 1.25 g of orange mercury(II) oxide (MM = 216.59 g/mol): 2 HgO(s) 2 Hg() + O2(9) 13. editor of your choice This NightWings name is Stealthsky Molar Mass: 159 See. Explanation of how to find the molar mass of Hg(NO3)2: Mercury (II) nitrate.A few things to consider when finding the molar mass for Hg(NO3)2:- make sure you.
