Answer:
On the left side of calcium atom.
Explanation:
There are two dots are present on the left side of calcium atom which represents the unpaired electrons present in the outermost shell. This structure is presented by Lewis in order to show the number of unpaired electrons in the atom. if the calcium atom loses these two electron during a chemical reaction so the two dots disappear and the calcium atom is now stable.
In magnet I believe nickle is used most often
Answer:
23.8 torr
Explanation:
Vapor pressure of a liquid is simply the pressure of the vapor that arises when the liquid evaporates in a closed container above the liquid sample.
From the question given above, the vapor pressure is 23.8 torr at 25°C. Since the temperature is constant, the vapor will remain the same when equilibrium is reached in the new container as vapor pressure depends on the temperature of the liquid.
Here, the number of protons are different. As they have different atomic numbers, it would be: "Isobars"
