Number 2 is 4 states they are condensation freezing melting and evaporation
The substances Oxygen and Hydrogen are elements.
<span>The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes of chlorine. Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units.
</span><span>The number 35.45u is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed </span><span>value. </span>
An ionic bond is a bond formed between a metal and a nonmetal atom, which is contrary to a molecular bond which is between nonmetals. Also, in ionic bonds, the atoms do not share electron like in molecular compound but one atom gain and the other lose balance electrons.
In comparison, ionic bonds are way stronger than molecular and they cause the formulation cations and anions (ions that are positive and negative, respectively).
Answer: d. Increasing the amount of benzoquinone
Explanation: The given situation can be written in terms of the equation as follows-
Catechol + Oxygen ⇆ Benzoquinone + water (catechol oxidase is the catalyst)
Le chatleir Principle for the system of equilibrium explains that whenever a reaction is being applied to the stress , the reaction will move in that direction in which the effect of stress is being lessened.
For example if there is a decrease in the concentration of the reactants, the equilibrium will shift to that direction in which the reactants concentration is being increased in order to maintain the equilibrium.
Thus the correct option is (D) as increasing the concentration of the benzoquinone, the equilibrium will shift in the direction in which its concentration is getting decreased, that is in backward reaction, thus decreasing the rate of reaction.
