Look at the single replacement reaction below. 3CuCl2 + 2Al → 2AICI3 + 3Cu Which best summarizes the steps to convert from moles of Copper (II) Chloride (CuCl2) to grams of Aluminum Chloride (AICI3)? O Use the molar ratio, then multiply by the molar mass of AICI3 O Multiply by the molar mass of CuCl2, then use the molar ratio. Use the molar ratio, then divide by the molar mass of AICI3 O Divide by the molar mass of CuCl2, then multiply by the molar mass of AICI3

A 4.86 g quantity of solid rubidiummetal is combined with 3.44 g of magnesium chloride crystals according to this chemical reaction: 2 Rb (s) + 1 MgCl2 (s) 1Mg (s) +2 RbCI (s) What quantity of magnesium metal will be produced? _g Mg round your answer using appropriate sig figs The following molar masses may or may not be needed, but are provided to save you time: • molar mass: Rb = 85.47 g/mol • molar mass: MgCl2= 95.21 g/mol • molar mass: Mg = 24.31 g/mol Hiint: Start with the number of grams of Rubidium

Relate the model to Chemistry: The balanced chemical reaction for producing water is: 2 H2 + 1 O2 → 2 H2O. Predict which reactant amounts (of the three examples shown below) would get the most water with the least amount of leftovers. Explain how your understanding of Limiting Reactant helped you figure this out.

Question 25 of 97 Submit DDT was an insecticide used to prevent mosquito borne diseases. Due to the harmful effects on birds and fish, it is now banned in the US. However, other countries still use it to control mosquitos. It can be prepared by the reaction shown below. Determine the amount of DDT that can be produced and the percent yield for this reaction. 2C6H,CI + C2HOCI, – C,4H9CI, + H20 2 3 NEXT If a company in South America started with 1175 g of chlorobenzene (C6H5CI, MW 112.55 g/mol) and 538.5 g of chloral (C2HOCI3, MW 147.39 g/mol), set up the table below that represents 100% yield with the given reaction conditions. 2C6H,CI C2HOCI, C1.H,Cls H2O Before (mol) Change (mol) After (mol) O RESET 3.132 -3.132 3.654 -3.654 7.308 0. + -7.308 10.44 -10.44 MacBook Air F12 II F8 F10 F11 000 F9 20 F3 F7 F4 F5 F6 esc F2 F1 +.
