Answer:
Activation of the ring towards substitution: NH2, OCOCH3
Withdrawal of electrons through resonance. COOH, SO3H
Explanation:
During electrophilic substitution, certain substituents may activate or deactivate the benzene ring.
Substitients that activate or deactivate the benzene ring may do so via resonance or inductive effect.
Groups such as -NH2 and OCOCH3 activate the ring via resonance while groups such as -SO3H and -COOH deactivate the ring via resonance.
I believe it is a large mass of warm air rises, replacing the cooler air above
Answer:
an Atom
Explanation:
A representative particle is the smallest unit of a substance that can be broken down without altering the composition. Atoms are the smallest particle that can be split. Substances that contain only one kind of atom are called elements.
Answer:
Reversible chemical reaction favoring products.
Explanation:
Hello,
In this case, if we assume the following chemical reaction to be carried out:
We understand that it is under equilibrium conditions. In addition, based on the law of mass action, the present equilibrium constant is defined as:
Now, if Keq is greater than 1, it means that the concentration of the product B is greater than that of the reactant A, therefore, even though it is a reversible chemical reaction, it is favoring the formation of B it means the product(s).
Best regards.
Answer:
548.089 J
Explanation:
-The molar mass of copper is 63.546 grams.
-We obtained the mass of 0.762 moles of copper:
-We apply the specific heat formula to calculate the amount of heat released:
Hence, the amount of heat released is 548.089 J
