Answer:
Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet. Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic
1 vitamin C is a critical micronutrient. It contributes to your immune defense system by supporting multiple cellular functions of your body's adaptive immune systems.
2 can also fight free radicals in the body, thereby decreasing inflammation and boosting immunity.

4HCl + MnO₂ → MnCl₂ + 2H₂O + Cl₂
2Cl⁻ → Cl₂ + 2e⁻
MnO₂ + 4H⁺ + 2e⁻ → Mn²⁺ + 2H₂O

Answer:
0.933 L
Explanation:
Since the pressure is the same, we use the equation
V = Volume
T = Temperature
Since we are given the temperature in Celsius, we need to convert it to Kelvin by adding 273:
-55.0 + 273 = 218
40.0 + 273 = 313
The gas will occupy a volume of 0.933 L.
(Side note - If the temperature increases, the gas will want to expand, leading to a higher volume.)
