Study the following unbalanced half-reaction. which equation represents the balanced half-reaction? h2o2 > h2o
e- + h+ + 2h2o2 h2o
2e- + 2oh- + h2o 2h2o2
2e- + 2h+ + h2o2 2h2o
3e- + 2h+ + 2ho- 4h2o
4e- + h2o2 2h2o +4e-

In order to calculate the amount of heat transferred you must know the __ and specific heat of the material, as well as the change in temperature. a. volume b. density c. mass d. enthalpy

Can you me with this i really appreciate it

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
