31 protons 31 electrons and 39 nutrons
The primary difference between them is what they work with and what their goals are. Chemical engineers research and design production processes for things like food or gasoline while nuclear engineers focus on ways to harness and use radiation and nuclear energy.
Answer:
Rise surface fall surface rise
Explanation:
Hope this helps!
We can apply Charles' law to find the change in the volume of the gas since the pressure in this chamber is kept constant.
Explanation:
- Charles' law states that at constant pressure, the change in temperature in a chamber will lead to change in its volume, which is to say that temperature and volume changes are directly proportional.
- The volume change here says that the gas expands as the temperature rises, give that the moles of the gas are constant.
- Hence, the equation could be,
So, Charles' law can be directly applied to the situation to find or analyse the changing the variables such as volume and temperature
Answer is: d. a lower melting point and boiling point.
Alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.
Bond between these elements is metallic bond.
Both the melting and boiling points decrease down the group 1, because the decrease in the strength of each metallic bond.
From top to bottom, atomic radius increase and the distance between the nucleus and delocalized electrons increases, so metallic bond is weaker (attractions fall).
Metallic bond is formed between electrons and positively charged metal ions.
