Agalvanic cell with e o cell = 0.30 v can be constructed using an iron electrode in a 1.0 m fe(no3)2 solution, and either a tin electrode in a 1.0 m sn(no3)2 solution, or a chromium electrode in a 1.0 m cr(no3)3 solution even though sn2+/sn and cr3+/cr have different reduction potentials. give the overall balanced reaction for fe-sn cell. do not include the states of matter.

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
