Answer:
Melting is the process of being changed from a solid to a liquid state especially by the application of heat. This occurs when the energy of the solid increases, which increases the substance's temperature to the melting point. Typically, the solids energy increases by the application of heat or pressure. At the melting point, the ordering of molecules in the solid breaks down to a less ordered state, and the solid "melts" to become a liquid.
hope this helps! :)
So in order to answer this we need the number of moles of oxygen and the right stoichiometry.
The balanced reaction should be 2HgO --> 2Hg + O2, therefore 2 moles of mercury are produced for every one mole of oxygen gas. Since we have the mass of O2 we can calculate the moles as moles = mass/RMM where RMM is the relative molecular mass of O2, which is 32 g/mol. Therefore the number of moles = 125/16 = 3.9 mol.
Since 2 moles of Hg are produced for every one mole of O2, the number of moles of Hg = 3.9*2 = 7.8 mol.

Answer:
The PH of the Acid
Explanation:
The PH scale contains 14 numbers
Acids are within 1 - 6 on the PH scale
Bases are within 8 - 14 on the PH scale
7 on the PH scale is neutral
A stronger Acid will be closer to 1
A weaker Acid will be closer to 6
The particles in a colloid are large enough to scatter light, a phenomenon called the Tyndall effect. Clouds are colloidal mixtures. They are composed of water droplets that are much larger than molecules, but that are small enough that they do not settle out.
