Answer:
Hydrogen is the smallest chemical element. It has one proton and one electron, making it neutral. However, the ions of hydrogen atom are charged species. Thus, the key difference between hydrogen atom and hydrogen ion is that the hydrogen atom is neutral whereas hydrogen ion carries a charge.
A semiconductor's resistivity decreases with the increase in temperature.
More is the heat imparted to it, it will behave more as an insulator.
Answer:
70.8 mmHg
Explanation:
To find partial pressure of carbon dioxide we first find the mole fraction of carbon dioxide
n (carbon dioxide) = 5/44.01 g/mol = 0.11361 mol
n (Helium) = 3.75 g/4 g/mol = 0.9375 mol
The partial pressure of carbon dioxide will be the mole fraction of carbon dioxide multiplied by the total pressure
Partial pressure = 0.11361g/(0.11361g + 0.9375 g)* 655 mmHg
= 70.8 mmHg
The answer would be B since it forms a solid
