Liquid crystal molecules have very unique structures, allowing them to be highly affected by electric fields, changing their orientation in the liquid crystal structure. This is why they are used in LCD screens. They are also highly sensitive to changes in temperature. Therefore the answer is C.
Hope this helps!
If you mean LiOH+HBr->LiBr+H2O
the answer is 0.4347mol LiBr and that equals (10/23)/80 gram LiBr
Answer:
3.91 × 10⁴ J/mol
Explanation:
We can calculate the heat of solution using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the solution
m is the mass of the solution
ΔT is the change in the temperature
The mass of LiCl is:

The mass of the solution is:
m = mLiCl + mH₂O = 10.6 g + 200.0 g = 210.6 g
Q = c × m × ΔT = (4.184 J g⁻¹ °C⁻¹) × 210.6 g × 11.08 °C = 9763 J
In a constant pressure calorimeter, the molar enthalpy of solution for LiCl is:

It should be the digestive system as it absorbs the nutrients of the food into your body.
