Answer:
Explanation:
Heat can transfer between objects in two different ways. Generally, heat will travel from places of higher heat to places of lower heat.
The first is conduction. This is when the object being heated and releasing heat are in direct contact. Not as much heat is lost in this process, since the thermal energy has nowhere else to go except for the object it is touching. An example would be putting a kettle on a hot stove, but it could also be grabbing a cold pole with your relatively warm hands.
The second is convection. This is where heat is radiated into the air, and thus, transferred by the air, to another object. The actual heat that you feel is actually electromagnetic waves, and its transfer from an object is called electromagnetic radiation. Convection is the heat you feel from a near fire or a space heater. This is also why wind is present in our atmosphere.
There is also radiation. This is caused from the burning or breaking down of a substance. This might come from the sun.
I hope I did enough to deserve the 45 points!
The answer is D because for light 3 to function switch d does not have to turn on

Answer:
2KClO3 (s) -------> 2KCl (s) + 3O2 (g)
Explanation:
Una ecuación de reacción química es una representación simbólica de lo que sucede en un recipiente de reacción.
Al escribir la ecuación de reacción química para una reacción particular, se utilizan los símbolos químicos de todas las especies involucradas.
Por la reacción. en el cual dos moléculas de Clorato de Potasio en estado sólido, al aplicar calor se descompone en dos moléculas de Cloruro de Potasio en estado sólido y tres moléculas diatómicas de Oxígeno en estado gaseoso, la ecuación de reacción se escribe así;
2KClO3 (s) -------> 2KCl (s) + 3O2 (g)
La regla para escribir ecuaciones de reacción química balanceada es que el número de átomos de cada elemento en el lado derecho de la ecuación de reacción debe ser el mismo que el número b de átomos del mismo elemento en el lado izquierdo de la ecuación de reacción.
Si realizamos un conteo de átomos simple en ambos lados de la ecuación de reacción, la regla se cumple
Answer:
Water: H2O --> [H+] + [OH-]
Ethyl alcohol: C2H5OH --> [C2H5O-] + [H+]
Explanation:
Dipole-dipole force is observed when an ionic compound ionizes (forms ions), revealing its slightly positive ion and slightly negatively ion.
The chemical formula of Water is H2O.
H2O --> [H+] + [OH-]
The chemical formula of ethyl alcohol is C2H5OH.
C2H5OH --> [C2H5O-] + [H+]
Note the positive and negative parts of both water and ethyl alcohol as expressed in the equations above.
