Answer:
High resistance
Low conductivity
Explanation:
The more resistance (aka less conductivity) there is, the more the energy is turned into heat than simply passing through the object.
We are asked to find the value of ΔG°rxn from the equilibrium concentrations of the reactants and products. We can use the following formula:
ΔG°rxn = -RTlnK
The value of R = 8.314 J/Kmol, T = 298.15 K and we are given the equilibrium constant Keq = 2.82.
The question provides equilibrium concentrations and then asks to find ΔG°rxn when more of a product is added to the reaction mixture. However, you are asked to find ΔG after the reaction has settled down and reached equilibrium once more. Therefore, we can simply use Keq = 2.82 still and solve for ΔG.
ΔG°rxn = -(8.314 J/Kmol)(298.15 K)(ln(2.82))
ΔG°rxn = -2570 J/mol
ΔG°rxn = -2.57 kJ/mol
Under equilibrium conditions at standard temperature and pressures, the value of ΔG°rxn = -2.57 kJ/mol.
Carbonic acid
dissolves limestone and other rocks. This is an example of chemical erosion. An
example is in the caves. Caves are formed where rainwater as it falls
through the atmosphere absorbs carbon dioxide. The carbon dioxide makes the
rain acidic to react it with the limestone bedrock. The rainwater is absorbed
by the soil into the ground. Then as it enters through the soil, the rainwater
will absorb more carbon dioxide that is produced by the decomposers. The carbon
dioxide with water reacts to form carbonic acid. The carbonic acid will react
to limestone and dissolves it slowly. As the space become larger, water can
enter into it.
Molarity is a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.
Answer: An existing theory is modified so that it can explain both the old and new observations.
