Answer:
Mole Fraction of O2 --> 0.42
Mole Fraction of Ar --> 0.037
Explanation:
Answer: The bond of molecule AB is then best described as a covalent bond
Explanation: The bond molecule AB is covalent because the difference in their electronegativity is not very big
Catalysts are substances that speed up the rate of a chemical
reaction. It is important to know that reacting species must first possess a
minimum amount of energy equal to the activation energy for the reaction
to proceed. The catalyst works in a way that lowers the activation energy
required for the reaction to proceed. In this way, the reaction occurs at a
faster rate than without a catalyst. Catalysts do not react with
the chemical species in the reaction, thus, they are not consumed. However, over
time, catalysts tend to degrade and their function is also reduced. When this
happens, new catalysts replace the poisoned ones. Catalysts are widely used
today since they bring an increase in the production rate of commercial chemicals.
Bromine attracts electrons more strongly. Cesium is In fact the least electro negative element.
Sodium is more likely to lose an electron because is is less electro negative. Strong electronegativity make the element want more electrons. Sodium has loose electrons with a lower electronegativity so it gives it up easier.
