Answer:
2×10^-5L
Explanation:
Since there are
1000mL in 1L
0.0200mL will give us
0.0200/1000
= 2×10^-5L
To convert 0.0200mL to liters, we use the conversion factor 1L = 1000mL. The calculation becomes 0.0200mL divided by 1000, which equals to 0.00002L.
The given question asks, how many liters are there in 0.0200mL given the conversion factor that there are 1000mL in 1L. To calculate this, we will use the known conversion factor and divide 0.0200mL by 1000. Here are the steps:
So there are 0.00002 liters in 0.0200mL.

b. HCl
c. HClO
d. HClO₂
e. HClO₃
b) Alkali metals; Noble gases
c) Noble gases; Alkali metals
The group with the highest ionization energy is(option c) noble gases due to their full electron shell, making it difficult to remove an electron. The group with the lowest ionization energy is(option c) alkali metals because they have only one electron in their outermost shell, which can be easily removed.
The answer to the question is (c) Noble gases; Alkali metals. Ionization energy is the energy required to remove an electron from an atom or ion. A higher ionization energy means it is harder to remove an electron.
Noble gases have the highest ionization energies because they have a full electron shell, so they do not readily give up an electron. On the other hand, alkali metals have the lowest ionization energy, because they have only one electron in their outer shell, which is relatively easy to remove.

Answer:
Keq= [KOH]^4 [O2]^3/[[KO2]^4
Explanation:
4KO2(s) + 2H2O(l) → 4KOH(s) + 3O2(g)
Looking at the equation, the correct equilibrium expression is shown in the answer. The equilibrium constant for a reaction is given by the active masses of species involved in the reaction. The relative molar coefficients of species are raised to the power of their molar concentrations to give the active mass of each specie. This active mass now goes into the equilibrium equation.
Water is not included in the equilibrium equation because, as a solvent, it is present in large excess.
