Answer:
greases
Explanation:
Ink is manufactured in two stages: first varnish (a mixture of solvent, resins and additives) is made and then pigments are mixed into it. Varnish is a clear liquid that solidifies as a thin film. It binds the pigment to the printed surface, provides the printability of the ink and wets the pigment particles. Ink made with color usually includes the following ingredients: petroleum distillate solvent, linseed oil, some form of organic pigments, and soybean oil. Inorganic pigments are not commonly used.
Additives play a critical role in the formulation and production of inks, helping to impart the necessary characteristics the ink needs, whether it is to run more smoothly on press or to protect the finished product.
However, grease is not one of the likely additives to ink hence it is not essentially used in ink production.
Answer: ok lets battle XD
Explanation:
All you can conclude is that something must be burning with an orange flame.
Actually, the "something" that must be burning is the hydrogen that is produced when the sodium reacts with the water:
2Na + 2H₂O → 2NaOH + H₂ + heat
So much heat is produced that the hydrogen catches fire and some of the sodium evaporates into the flame.
The electrons in the sodium atoms get "excited" in the flame. When they drop back to a lower energy level, they emit energy in the form of an orange-yellow light.
