There’s no formula that relates solubility to temperature, but you can look up the solubility constant Ksp of substance given and then take the square root of that to find solubility.

Calculate the change internal energy (ΔE) for a system that is giving off 65.0 kJ of heat and is performing 855 J of work on the
ollegr [7]

Answer:  -64.1 kJ.  

Explanation:

According to first law of thermodynamics:

\Delta E=q+w

\Delta E=Change in internal energy

q = heat absorbed or released

w = work done or by the system

w = work done by the system=-P\Delta V  {Work is done by the system is negative as the final volume is greater than initial volume}

w = -855 Joules = 0.855 kJ     (1kJ=1000J)

q = -65.0 kJ  {Heat released by the system is negative}

\Delta E=-65.0J-(-0.855J)=-64.1kJ

Thus the change internal energy (ΔE) for a system that is giving off 65.0 kJ of heat and is performing 855 J of work on the surroundings is -64.1 kJ.

10. Identify the products in the combustion of methane.
Oksanka [162]

Answer:

a. CO2 and H20

Explanation:

Chemically, this combustion process consists of a reaction between methane and oxygen in the air. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. The following reaction represents the combustion of methane:

CH4[g] + 2 O2[g] -> CO2[g] + 2 H2O[g] + energy

One molecule of methane, (the [g] referred to above means it is gaseous form), combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy.
