Be sure to answer all parts. label the reactants and products, and indicate how many atoms of each type of element are present on each side of the following equations. a. 2 h2o2(aq) → 2 h2o(l) + o2(g) b. 2 c8h18 + 25 o2 → 16 co2 + 18 h2oc. 2 na3po4(aq) + 3 mgcl2(aq) → mg3(po4)2(s) + 6 nacl(aq)

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.
