// COMBUSTION_PROTOCOL


INIT: Use Sandpaper to remove oxide layer > Drag to Heat Source.

SAND
Sandpaper
Mg Ribbon
MgO (White Ash)
298K

Theory: Combustion Analysis

Magnesium is highly reactive. The ribbon is coated in Magnesium Oxide (MgO) which passivates the metal. Abrasion exposes the pure Mg.

Ignition results in a blinding chemiluminescence.

2Mg(s) + O₂(g) → 2MgO(s) + Energy

// SLAKING_PROTOCOL


ACTION: Inject H₂O into the system.

CaO (Quicklime)
298K

Theory: Exothermic Output

Quicklime (CaO) hydrolysis is highly exothermic. The energy released vaporizes a portion of the water.

CaO(s) + H₂O(l) → Ca(OH)₂(aq) + Heat

// FREEZING_PROTOCOL


ACTION: Mix NH₄Cl into Ba(OH)₂ Beaker.

Ba(OH)₂
NH₄Cl
298K

Theory: Endothermic Intake

This solid-solid reaction forces the absorption of lattice energy, dropping ambient temperature drastically.

Ba(OH)₂·8H₂O + 2NH₄Cl → BaCl₂ + 2NH₃ + 10H₂O

Mr Chemcoach Digital-Lab SIMULATION State: Ready
BaCl₂
Reaction
Na₂SO₄

THEORY

When Barium Chloride reacts with Sodium Sulphate, an exchange of ions occurs.

BaCl₂ + Na₂SO₄ → BaSO₄↓ + 2NaCl

OBSERVATION

A white precipitate of Barium Sulphate (BaSO₄) is formed instantly upon mixing.

// METAL_WATER_PROTOCOL


ACTION: Drop metal into water and observe reactivity (fizz, flame or explosion).
