The balanced equation is 2HgO --> 2Hg + O2
Yes the water boils but it doesn't become water gas it becomes just gas also known as evaporation
Answer:
a. Electric Energy
b. Light Energy
c. Thermal Energy
Explanation:
a. When a lamp is turned on by means of a switch, electric energy is usually used, since that is the form of energy that is generated when there is a potential difference between two points, which allows to establish an electric current, that electric current travels through the wires up to the bulb of the lamp
b. In this case a case of light energy is presented since that is the energy transported by the light and that is manifested on the matter in different ways, one of them is to remove the electrons from the metals. This is what usually happens in some types of light bulbs, that when the displacement of the electrons is promoted, a beam of light is generated.
c. The last case is a case of thermal energy, since this energy is that expressed as the total kinetic energy resulting from the random movements of atoms and molecules. This was what could happen in case b, when the beam of light was generated. This energy is released in the form of heat, and may present high temperatures.
Answer:her weight
Explanation:
weight varies from place to place (you weight differs on earth than is does the moon), her mass however always stays the same wherever she may be
<span>The ionisation eq for MNCO3 is given by
MnCO3 --> Mn^2+ + CO3^2-
Recall Ksp=[Mn^2+][CO3^2-]
From the chemical reaction one moles of manganese and carbon reacts
Here molar solubility of MnCO3 is 4.2 * 10^-6 M;
Which means that when 4.2 * 10^-6 moles of [Mn^2+] reacts, it also reacts with 4.2 x 10^-6 M of CO3
Thus Ksp= 4.2 x 10^(-6) x 4.2 x 10^(-6) = 17.64 * 10^(-6+(-6)) = 17.64 * 10^(-12)</span>
