Answer:
Stannic fluoride, SnF4
Explanation:
The chemical formula of Barium nitride is Ba(NO3)2.
The chemical formula of Cobaltous chloride is COCl2.
The chemical formula of Sodium Oxide is Na2O.
So the correct one is stannic fluoride, SnF4.
Answer:
sodium carbonate decahydrate
Explanation:
Usually we would the molar mass of Na2CO3 x 10 H2O. This is where the name comes from.
Answer:
Heat energy.
Explanation:
The exited electron releases the absorbed energy as heat energy that provides energy to electrons to move from one orbit to another orbit. The electron avails kinetic energy which provides motion in the electron when the energy is absorbed by the electron while on the other hand, electron releases energy which brings the electron into its original orbit. So we can say that the electrons releases energy in the form of heat and come back to its original place.

Answer:
a. C > F > Cl
Explanation:
We know that atomic mass of Chlorine is greater than of Florine than that of carbon. Moreover, in CF2Cl2, therefore, there are two atoms of Cl, F and one atom of C. Therefore, in CF2Cl2 in order of decreasing mass percent composition C > F > Cl. Therefore, the correct option is a.
