A) For the reaction 4Cr(s) + 3O2(g) → 2Cr2O3(s) calculate how many grams of the product form when 21.4 g of O2 completely reacts. Assume that there is more than enough of the other reactant. B) For the reaction 2Sr(s) + O2(g) → 2SrO(s) calculate how many grams of the product form when 21.4 g of Sr completely reacts. Assume that there is more than enough of the other reactant. C) For each of the following precipitation reactions, calculate how many grams of the first reactant are necessary to completely react with 18.0 g of the second reactant. 2KI(aq) + Pb(NO3)2(aq) → PbI2(s) + 2KNO3(aq) Na2CO3(aq) + CuCl2(aq) → CuCO3(s) + 2NaCl(aq) K2SO4(aq) + Sr(NO3)2(aq) → SrSO4(s) + 2KNO3(aq)

Transcript

00:01 To balance this reaction, a combustion reaction, we'll first focus on the carbons. 00:08 We have c3, h8, o3, reacting with oxygen to produce co2 and h2. 00:22 With three carbons and one carbon, we need to put a three here. 00:27 With eight hydrogens and two hydrogens, we need to put a four here. 00:32 And then we have six plus four, so that's ten oxygens. 00:42 We've got three oxygens and two oxygens. 00:46 So with three, we need seven more. 00:48 How do we get seven out of two? we multiply that by seven halves. 00:54 So now we'll get rid of the fractions by multiplying everything through by two. 01:03 And we get a seven, a six, and an eight. 01:08 So when the following equation is balanced, the coefficient on c3h8 -03 is 2. 01:26 Then for number 4, a is s for sodium, b is f -e for iron. 01:35 The only one that is correct is f -e is iron. 01:39 Sodium is n -a, not s, bromine is br, not b, tin is s -n, and neon is n -e, not n. 01:50 So this is the only one that's correct...
