Answer:
Anion
Explanation:
Anion is an atom or group of atoms that are negatively charged.
Cations are positively charged
Anode is a positively charged pole that conducts electricity (remember electrolysis)
Cathode is a negatively charged pole that conducts electricity (remember electrolysis too)
Since
21.2 g H2O was produced, the amount of oxygen that reacted can be obtained
using stoichiometry. The balanced equation was given: 2H₂ + O₂ → 2H₂O and
the molar masses of the relevant species are also listed below. Thus, the
following equation is used to determine the amount of oxygen consumed.
Molar mass of H2O = 18
g/mol
Molar mass of O2 = 32
g/mol
21.2 g H20 x 1 mol
H2O/ 18 g H2O x 1 mol O2/ 2 mol H2O x 32 g O2/ 1 mol O2 = 18.8444 g O2
<span>We then determine that
18.84 g of O2 reacted to form 21.2 g H2O based on stoichiometry. It is
important to note that we do not need to consider the amount of H2 since we can
derive the amount of O2 from the product. Additionally, the amount of H2 is in
excess in the reaction.</span>
The characteristics of enzymes that give them this effectiveness as catalysts are they are made up of protein, they do not consume in the reaction ad lower the activation energy.
<h3>What is an enzyme?</h3>
The enzyme is a biological catalyst. The substrate is bound to them, and they supply the activation energy. It is the quantity of energy needed to initiate the reaction.
They are effective catalysts, as a small amount of them can affect a large amount of reaction.
Thus, enzymes are made of protein, do not consume in the reaction, and have reduced activation energy, which contributes to their efficiency as catalysts.

Among the given compounds, <span>CH3CH2CH2OH (1-propanol) will have maximum solubility in water.
Reason:
Solubility is based on the principle of 'Like dissolves Like'. Hence, water is a polar solvent, hence it will dissolve polar solvent to maximum extent. Among the listed solutes, </span>CH3CH2CH2OH has maximum polarity.
<span>
Further, </span>CH3CH2CH2OH is capable of displaying hydrogen bonding with water, while other compounds will not show hydrogen bonding. With reference to hydrogen bonding, it may be noted that when hydrogen atom is bonded to electronegative elements like O, N and F, it exhibits hydrogen bonding. Due to this, CH3CH2CH2OH will be readily soluble in water. <span>
