Try to reduce the amount of leftover ingredients by changing the amount of one, two, or all three starting ingredients. Show your stoichiometric calculations below. Water = 946.36 g Sugar = 196.86 g Lemon Juice = 193.37 g Lemonade = 719.84 g Just Lemons Lemonade Recipe Equation: 2 water + sugar + lemon juice = 4 lemonade Mole conversion factors: 1 mole of water = 1 cup = 236.59 g 1 mole of sugar = 1 cup = 198 g 1 mole of lemon juice = 1 cup = 229.96 g 1 mole of lemonade = 1 cup = 225.285 g Leftover ingredients: ? Percent yield: ?

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
