Answer:
The salt and sugar as well as the baby power and granulated sugar are the independent variables.
The dependent variable is how it reacts (will it dissolve or not)
Explanation:
Answer:
Check the image file attached
Explanation:
Using an example like Christmas lights, I would say yes because normally a lot of them would go out if one light is broken.
Is there any more info lol
But from thinking I got A=DH^2*BC
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.
