Answer:
The molar mass and molecular weight of Sn(CO3)2 is 238.728.
Explanation:
If the crucible wasn't covered with a lid the reactants may have produced a gas that was released into the surroundings, or mass may have been lost in the form of water vapour.
The answer would be "air, wood". Gases have the highest Kinetic energy and least Potential energy. Liquids have the 2nd highest Kinetic energy and 2nd least potential energy and solids have the least kinetic energy and highest potential energy.
It’s water vapor, does this help?
Answer: Option (d) is the correct answer.
Explanation:
Metals are the species which contain more number of electrons.
When a specie loses electrons then it acquires a positive charge. Whereas when an atom gains electrons then it acquires a negative charge.
Thus, as metals have more number of electrons, therefore, in order to gain stability metals readily lose electrons.
Hence, metals naturally form positive ions, by losing electrons to empty the valence shell.
