Which of the following is an acid-base neutralization reaction? naoh + hcl yields nacl + h2o 2nacl + h2so4 yields na2 so4 + 2hcl c6h12o6 + 6o2 yields 6co2 + 6h2o 2h2 + o2 yields 2h2o

How many atoms of oxygen are contained in 160 grams of n2o3

Which statement correctly describes metallic bonds? a. they form when certain atoms lose electrons and other atoms gain electrons. b. they involve an attraction between anions and cations. they always involvpoth a metal and a nonmetal. d. they can only form between atoms of the same element. e. they form because electrons can move freely between atoms.

The characteristics 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 an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
