Answer:
The voltage or potential difference
Explanation:
What makes current flow in a circuit is the voltage or the potential difference.
This force is supplied by the battery or the mains electrical circuit.
- Every circuit requires the voltage to drive current through
- When a circuit is complete, the battery is able to overcome any resistance by the generating enough voltage which is the force to drive the current through.
Answer:
b is the anwer
Explanation:
the option is the explanation
Answer:
I think section #3
Explanation:
When i was in science class in my memory it was always in that area
Atomic number is equal to protons and electrons, so the answer is 5
Enthalpy is a state function
Explanation:
The Hess's law allows us to determine the enthalpy change of a reaction because enthalpy is a state function. It does not depend on the individual path take in going from reactants to products in the reaction.
- Enthalpy changes are the heat changes accompanying physical and chemical changes.
- It is the difference between the heat content of product in the final state and the reactants.
- Enthalpy changes for some reactions are not easily measurable experimentally.
- To calculate such heat changes, we apply the Hess's law of heat summation.
- The law states that "the heat change of a reaction is the same whether it occurs in a step or several steps".
- The Hess's law is simply based on the first law of thermodynamics by which we know that energy is conserved in every system.
