Given the following equation formats, which form matches a single replacement reaction?
O AB + CD → AD + CB
O A+B → AB
O A + BC → AC + B
O AB → A+B

Which element would mostly likely have an electron affinity measuring closest to zero

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

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.
