Answer:
Using cobalt glass could be helpful to identify elements that weakly emit blue and/or violet.
Explanation:
Answer:
1) BaCl2+K2So4 → BaSo4+ KCl
2) Zn+AgNO3 → Zn+NO3+Ag
Answer:
Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product.
Crystallization, or crystallisation, is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The smallest entity of crystal lattice is called a unit cell, which can accept atoms or molecules to grow a macroscopic
crystal.

Answer:
The correct answer is:Oxygen is more electronegative than carbon. See the explanation below, please
Explanation:
The electronegativities of oxygen and carbon are: 3, 44 and 2, 55 respectively. The electronegativity is defined as the capacity that a given atom has for the attraction of electrons, by forming a chemical bond. Polarity is related to electronegativity. The greater the difference in electronegativities between two atoms, the polarity of the bond they form will be greater.
