# Identifying Endothermic and Exothermic Reactions

This table categorizes various reactions as either endothermic or exothermic. Each reaction needs to be identified and marked with the corresponding sign:

| Reaction                                                                                   | Exothermic or Endothermic | Sign |
|--------------------------------------------------------------------------------------------|---------------------------|------|
| Steam condensing                                                                           |                           |      |
| Ice melting                                                                                |                           |      |
| Water freezes                                                                              |                           |      |
| Tiny droplets of boiling water accidentally strike your skin                               |                           |      |
| Two atoms combine to form a molecule (2Br (g) → Br₂ (g))                                  |                           |      |
| An electron is removed from an atom (K (g) → K⁺ (g) + e⁻)                                 |                           |      |
| An ionic compound is dissociated to produce two ions (NaCl (g) → Na⁺ (g) + Cl⁻ (g))     |                           |      |
| Calcium chloride is mixed with water, resulting in a very hot solution                     |                           |      |
| Ammonium nitrate is mixed in water, resulting in a very cold solution                      |                           |      |
| Sparks from a sparkler that strike your skin                                               |                           |      |
