what is the Thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production?
postnew [5]

The thermodynamics of leaching of ilmenite in hydrochloric acid for titania pigment production is an industrial production of nano-sized titanium dioxide (TiO2).

<h3>What is thermodynamics?</h3>

Thermodynamics is defined as the change in the energy of system that brings about work in that system.

The leaching of ilmenite which is a titanium-iron oxide mineral with HCl can lead to the production of titanium dioxide (TiO2).

The use of thermodynamics in this process controls the heat and energy of the leaching system leading to a better yield of final products.

What is one advantage of doing a feild experiment instead of a laboratory experiment
Ber [7]

Answer:

  Field experiments can often have the potential to give scientists opportunities that are not possible in a lab setting.

Explanation:

  Having people "act natural" in a lab setting is impossible to truly achieve, as we all know what happens to our mental state and behavior when we are being actively observed. This is also especially helpful when conducting wildlife research, as there are a myriad of different things influencing animal and plant behavior that would be nigh impossible to recreate perfectly in a controlled lab setting.

  Field research can have its disadvantages as well, as it is very hard to only have one thing change (make an independent variable) in a wild environment with ever-changing weather, social effects, etc. Also, you, as the researcher, as causing an impact on the very location that you are observing, which can alter your results in unpredictable ways.

  The thing to remember is that each type of study has its advantages and disadvantages; if they didn't, then we'd all do the same type of research! You have to weigh your research options and figure out which one works best for your situation :)

How many protons and neutrons are in the nucleus of isotope with mass of 68.926 amu?
atroni [7]
<span>Isotopes are atoms of the same element with the same number of protons and same number of electrons but with <span>different number of neutrons. They differ in the number of neutrons that is why they also differ in mass numbers. Since they have the same number of protons, they have the same atomic number.
For instance, when the nucleus of the isotope with a 68.926 amu, there are 30 protons and 39 neutrons in the nucleus. The best example for this is Zn (zinc-69 isotope) and Ga (gallium-69 isotope) which has 68.926 amu and 68.925 amu respectively. </span></span>

D, Urine.

Just google what sweat is made of and it gives you all of the answers except for urine. Also you’d probably smell really bad if your sweat had urine in it. Hope this helps! :)
