like many metals , aluminum reacts with a halogen to give a metal halide 2 Al(s) + 3 Br2(l) = Al2Br6(s) what mass of Br2 , in grams , is required for complete reaction with 2.56 g of Al? what mass of white, solid Al2Br6 is expected?

3) P, + 5 02 → P,010 When elemental phosphorus oxidizes, it produces a covalently bonded molecule known as tetraphosphorus decoxide. What is the limiting reactant if 1.33 g of P4 reacts with 5.07 g of oxygen gas? What is the theoretical yield of P.O10?

Standard airbags for automobiles used to implement the formation of sodium azide as a source of nitrogen gas. This has since been replaced due to the potential caustic nature of the products. The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen oxide in liquid ammonia: 3N2O(g) + 4Na(s) + NH3(l)→ NaN3(s) + 3NaOH(s) + 2N2(g) a. You have 65.0 g of sodium and a 35.0 L flask containing N2O gas with a pressure of 2.12 atm at 296 K. What is the maximum possible yield (in grams) of the NaN3?

1) 2 Cu + S> Cużs When copper is heated with sulfur, the reaction above takes place. If 100. g of Cu is heated with 50.0 g of sulfur, which is the limiting reactant? What is the theoretical yield of Cu>S?

Consider the following reaction: If 10.0 g of KF are used, how many grams of CaF2 can be formed? Ca(NO3)2 (aq) + 2 KE (aq) → CaF₂ (s) + 2 KNO3(aq)

Look at the balanced chemical equation for the reaction between copper and nitric acid: Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) + 2H2O(l) + 2NO2 (g) How many grams of nitrogen dioxide would be produced if 2.47 g of copper were reacted with excess of nitric acid?

Cryolite, Na, AlF,(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. Balance the equation for the synthesis of cryolite. equation: Al,0,(s) + NaOH(1) + HF(g) → Na, AIF, + H,O(g) 6. If 13.4 kg of Al,0,(s), 56.4 kg of NaOH(1), and 56.4 kg of HF(g) react completely, how many kilograms of cryolite will be produced? mass of cryolite produced: kg Na, AIF, Which reactants will be in excess? HF NaOH Question Source: McQuarrie, Rock, And Gallogly 4e - General Chemsitry Publisher: University Science Books S A étv Aa MacBook Air 80 000 000 DII DD F3 F4 F5 F6 F7 F8 F9 F10 F11 F12

Antimony is alloyed with lead to increase the rigidity of components used in the construction of lead storage batteries.1.304 g of a particular metallic alloy, compounded of only Pb and Sb, can be quantitatively converted into a 1.511-g mixture of the oxides PbO2 and Sb2O4.What was the percentage (by mass) of antimony in the alloy?

Consider the following reaction: Zn(s)  +  Cu2+(aq)  ⟶    Cu(s)  +   Zn2+(aq) Which reactant is oxidized?

A     student     carried     out     the     reaction     below     starting     with     1.993     g     of    unknown     (X2CO3),     and    found    that    the    mass    loss    due    to    CO2 was    0.593    g.        X2CO3(s)        +        2    HCl(aq)        →        2    XCl(aq)        +        H2O(l)        +        CO2(g)       5. What    is    the    molar    mass    of    the    alkali    metal    X?
