Answer:
68.97g of milk must be added
Explanation:
To solve this problem we need to use the equation:
Q = C*m*ΔT -Coffee cup calorimeter equation-
This equation relates mass and change in temperature with heat of solution, Q.
The energy that decreases in the milk is the same that increases in the milk. That is:
Q(milk) = Q(tea)
Using the equation:
4.184J/molK* Mass milk * (65.0°C - 7.00°C) = 4.184J /molK * 200g (Tea) * (85.0°C - 65.0°C)
Mass milk * 58.0°C = 200g * 20.0°C
Mass milk = 4000g°C / 58.0°C
Mass milk =
68.97g of milk must be added
Compound B will be propene as a result of an elimination reaction involving potassium tert-butoxide and an alkyl halide. In proton NMR, alkenes exhibit signals in the 5–6 ppm range.
<h3>What are Elimination Reactions?</h3>
Elimination reactions are one sort of reaction that are mostly utilized to convert saturated compounds (organic molecules that contain single carbon-carbon bonds) to unsaturated compounds (compounds that feature double or triple carbon-carbon bonds). Additionally, it plays a significant role in the production of alkenes.
The elimination response is composed of the following three major events:
- Proton exclusion.
- The synthesis of a C-C pi bond.
- As a result, the relationship between the departing group's members has grown increasingly distant.

Answer:
Titanium (III) bromide
Explanation:
As it is an ionic compound we write the valency for transition elements, and that means here that titanium loses three electrons to become +3 (Ti
