the chemical equation will be XY2
Answer:
If you have ever been in a room when a piping hot pizza was delivered, you have been made aware of the fact that gaseous molecules can quickly spread throughout a room, as evidenced by the pleasant aroma that soon reaches your nose. Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many different directions before reaching the desired target.

Answer:
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
Explanation:
The formula for for the heat (q) absorbed by an object is
q = mCΔT, where
m = the mass of the sample
C = the specific heat capacity of the sample. and
ΔT = the change in temperature
1. What you must do
- Look up the specific heat capacity of AlF₃
- Calculate ΔT
- Calculate the mass of AlF₃
2. Sample calculation
For this example, I assume that the specific heat capacity of AlF₃ is 1.16 J·K⁻¹mol⁻¹
.
(a) Calculate ΔT
(b) Calculate m
