Answer:

Most metals have <u>luster</u> which means they <u>reflect</u> light

Explanation:

When light, which is made up of energetic photons, comes in contact with the surface of a metal, it is absorbed due to the corresponding energy gaps present between the metal orbital. The absorbed photons results in the raising of the energy levels of electrons within an atom of the metal which later drop back to a lower energy level and re-emit the photons which can now be observed as the metallic luster.

A piece of copper alloy with a mass of 85.0 g is heated from 30. °C to 45 °C. In the process, it absorbs 523 J of energy as heat
Ne4ueva [31]

Answer:

410.196 J/[kg*°C].

Explanation:

1) the equation of the energy is: E=c*m*(t₂-t₁), where E - energy (523 J), c - unknown specific heat of copper, m - mass of this copper [kg], t₂ - the final temperature, t₁ - initial temerature;

2) the specific heat of copper is:

c=\frac{E}{m*(t_2-t_1)}; \ => \ c=\frac{523}{0.085*(45-30)}=\frac{523}{1.275}=410.196[\frac{J}{kg*C}].

Is this equation completely balanced? 2C8H8 + 25O2 8CO2 + 18H2O No, because the number of carbon, hydrogen &amp; oxygen atoms on
Sergio039 [100]
<span>So to make it clear let's break the equation down species by species and assess the number of each species on bothe sides of the equation:
                   2C</span>₈H₈  +  25O₂   →   8CO₂ +  18H₂<span>O
LHS:  C - 16                                           RHS:  C - 8
          H - 16                                                     H - 36
          O - 50                                                    O - 34

Thus based on that it is evident that the equation is not quite balanced.  This therefore means a "</span><span>No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal."

</span>The actual balance equation would be C₈H₈  +  10O₂   →   8CO₂ +  4H₂O
