The smoke form burning tobacco can condense to form a black tar.
When magnesium burns in air, it forms magnesium oxide (MgO). This is a white powder that is a result of the reaction between magnesium and oxygen.
Magnesium oxide
Often it's an oxide. For example, carbon burns in air to form its oxides, carbon monoxide and carbon dioxide. However, there are other possibilities. Hydrogen burns in oxygen to produce water.
If mixing a substance with water forms a suspension, it suggests that the substance has low solubility in water. This means that the substance does not fully dissolve in the water and instead forms a heterogeneous mixture with visible particles suspended in the liquid.
A solid substance that forms when two liquids are mixed is called a precipitate. This occurs when chemical reaction between the two liquids forms a new solid substance that is insoluble in the mixture.
magnesium oxide
The sticky substance that forms when tobacco is burned is called tar. It is a dark, thick residue that can accumulate in the lungs and contribute to various health issues, such as respiratory problems and lung cancer.
When magnesium burns in air, it forms magnesium oxide (MgO). This is a white powder that is a result of the reaction between magnesium and oxygen.
Your nose has this sticky stuff coating the inside of it. when you breath in through your nose all of the bacteria, dirt, and chemicals you inhale stick to the substance and it forms a bugger.
Plaque

Some are, some are not. -Name your glue -

An asphalt is a sticky, black, viscous liquid or semi-soid, present in most forms of crude petroleum and some natural deposits, or the concrete made from such substance, used for roads and walkways.
compound
Often it's an oxide. For example, carbon burns in air to form its oxides, carbon monoxide and carbon dioxide. However, there are other possibilities. Hydrogen burns in oxygen to produce water.
A substance is considered hygroscopic if it has a tendency to absorb moisture from the air. This absorption may lead to an increase in weight or changes in physical appearance, such as clumping or becoming sticky. One common test is to leave the substance exposed to air and see if it becomes damp or forms clumps over time.
