Which statements are TRUE for the titration of Fe with Ce" to give Fe" and Ce? 1. Before the equivalence point, the indicator electrode potential is calculated using the Fe /Fe halt-reaction because both (Fe") and (Fe•) are known. 2. At the equivalence point, the indicator electrode potential is the average of E for the Fe"/Fe half-reaction and the Ce"/Ce hait reaction, 3. After the equivatence point, the indicator electrode potential is calculated using the Cet/Cel- half-reaction because both (Ce l and (Ce") are known None of the statements are true 2 and 3 O1.2 and 3 O 1 and 3 O and 2

To estimate the boiling point of Oganesson by extrapolating the data for theboiling points of the other noble gases. The boiling points of the noble gases are given below: Helium -269oCNeon -246oCArgon -186oCKrypton -153oCXenon -108oCRadon -62oC 1. Make a nicely labeled graph of boiling point vs. number of electrons.Using this graph, extrapolate your data to make a prediction for the boiling point of oganesson.2. A brief explanation of why this method can be used to make a reasonableestimate of the boiling point of oganesson Your explanation should include a description of the intermolecular forces that are present in samples of these elements, and how they affect their boiling points.

Each sketch below shows three objects with an electric charge. In each case, decide whether there is a net force acting on the object outlined in green. If there is a net force, decide whether it pushes the green-ring object to the left or right. Then select the appropriate button under the sketch. For example, if there is a net force pushing the green-ring object in the first sketch to the left, select the left button under the first sketch. If there is no net force on the green-ring object in the second sketch, select the middle button under the second sketch. And so on. ola -2 +3 -2 -2 I Don't Know Submit 2022 McGraw Hill LLC.
