Answer:
that so hard man its okay
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.

Answer:
The answer to this question would be:
2. The exponents need to be the same so the leading numbers can be added or subtracted.
3. The result has the same number of decimal places as the least precise number.
The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5
The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.

Moles of cu = mass/Ar
= 5/Ar
=ans
1 mole = 24dm3
Vol of cu = ans/1 × 24dm3
=ans
sorry i have no calculator with me now
