Fe + NiSO4 ----> FeSO4 + No
NaF + HI ---> NaI + HF
The heat in particles travels through convection at a certain speed depending on what density a mass has.
The equation N2+H2= NH3 is balanced. This is because N2 + 3H^2 ➡️ 2NH^3
Answer:

Explanation:
The volume and amount of gas are constant, so we can use Gay-Lussac’s Law:
At constant volume, the pressure exerted by a gas is directly proportional to its temperature.

Data:
p₁ =5.7 atm; T₁ = 100.0 °C
p₂ = ?; T₂ = 20.0 °C
Calculations:
1. Convert the temperatures to kelvins
T₁ = (100.0 + 273.15) K = 373.15
T₂ = (20.0 + 273.15) K = 293.15
2. Calculate the new pressure

Answer: silicon Si, Germanium GE
