Answer:
Explanation:
Hello.
In this case, since the second-order rate law is:
Whereas the subscript A accounts for C2F4 and its integration turns out into:
Thus, for the initial concentration of C2F4 computed via the 0.1 mol in the 2.31-L container:
The final concentration after 2.1 h is:
Solving for the final concentration of C2F4, we obtain:
Best regards.
Answer:
circuit
electric current
voltage difference
ohms law
resistance
Explanation:
Circuit - a roughly circular line, route, or movement that starts and finishes at the same place.
Electric current - A net unidirectional movement of electrons, or other charge carriers, caused by a potential difference
Voltage difference - A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
Ohms law -a law stating that electric current is proportional to voltage and inversely proportional to resistance.
Resistance - The refusal to accept or comply with something; the attempt to prevent something by action or argument.

Answer:
This was important because it supported the concept of discovery of new elements
Explanation:
Mendleev left gaps in his table not discovered at that time, but he predicted the properties (chemical and physical) of undiscovered elements. Mendeleev left the gap next to silicon and named the undiscovered element as 'eka-silicon', the element germanium was discovered later.
Answer : The number of moles of NaCl present in a solution are, 1.07 moles.
Explanation : Given,
Molarity of = 8.59 M
Volume of solution = 125 mL = 0.125 L (1L = 1000 mL)
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the number of moles of NaCl present in a solution are, 1.07 moles.
