What is the mass of copper that increases its temperature by 285 degrees celsius when 186,000 j of energy is applied?
Llana [10]
From reliable sources in the web, it may be searched that the specific heat of copper is approximately equal to 0.385 J/gC. The amount of heat that is required to raise a certain amount by certain number of degrees is given in the equation,
                              H = mcpdT
where H is heat, m is mass, cp is specific heat, and dT is temperature difference. Substituting the known values,
                           186,000 J = (m)(0.385 J/gC)(285C) 
                                     m = 1695.15 g

Which result occurs during an exothermic reaction?(1 point)
vekshin1

The result which occurs during an exothermic reaction is: C. Light and heat are released into the environment.

A chemical reaction is defined as a chemical process involving the continuous transformation and rearrangement of either the ionic, atomic or molecular structure of chemical elements, especially through the breakdown and formation of chemical bonds, so as to produce a new chemical compound.

Basically, the two (2) main types of chemical reaction are;

  • <u>Endothermic reaction:</u> this is a chemical reaction in which heat is absorbed .

<u>Exothermic reaction:</u> this is a chemical reaction in which light and heat is liberated (released) into the environment.

In an exothermic chemical reaction, light and heat energy is liberated (released) when the energy of the products is lesser than the energy of the reactants.

In conclusion, light and heat is liberated (released) into the environment during an exothermic reaction.
