Answer:
Explanation:
Froath flotaion process is based on thie wttebality properteis like hydrophillicity and hydrophobicity.
Incase of sulphide ore processing,
The metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. By doing thise you are sperating required sulphide ore particels from unwanted gaunge , by doing this you are incresing the concentation of Sulfide in ore by removing the not required gaunge particles.
Hope this helps you to decide your annswer
A. CI, Br
Explanation:
Different kinds of atoms bind their valence electrons with various amounts of energy. In order to remove the valence electrons, enough energy must be available.
The amount of energy required for the removal of an electron is the ionization energy or ionization potential.
The ionization energy depends on:
- Nuclear charge
- Atomic radius
- Sublevel accomodating the electron to be removed.
- Special stability of half or fully filled sublevels.
Across a period, the ionization energy increases.
Down a group ionization energy decreases due to increasing atomic radii.
Cl and Br are in the same periodic group. Cl is element number 2 and Br is element 3 in the group of the halogens.
Therefore, Cl will have a higher ionization energy compared to Br.

This problem is describing a gas mixture whose mole fraction of hexane in nitrogen is 0.58 and which is being fed to a condenser at 75 °C and 3.0 atm, obtaining a product at 3.0 atm and 20 °C, so that the removed heat from the system is required.
In this case, it is recommended to write the enthalpy for each substance as follows:
Whereas the specific heat of liquid and gaseous n-hexane are about 200 J/(mol*K) and 160 J/(mol*K) respectively, its condensation enthalpy is 31.5 kJ/mol, boiling point is 69 °C and the specific heat of gaseous nitrogen is about 29.1 J/(mol*K) according to the NIST data tables and and are the mole fractions in the gaseous mixture. Next, we proceed to the calculation of both heat terms as shown below:
It is seen that the heat released by the nitrogen is neglectable in comparison to n-hexanes, however, a rigorous calculation is being presented. Then, we add the previously calculated enthalpies to compute the amount of heat that is removed by the condenser:
Finally we convert this result to kJ:

Cars might not be as insulated and as safe because of the need to get cooler air into the vehicle, and im not fully sure but refrigerators would still run on ice to cool food. Houses wouldnt be as insulated from heat so when winter came around you would be colder than normal <span />
