Answer:
47.2 g
Explanation:
Let's consider the following double displacement reaction.
3 FeCl₂ + 2 Na₃PO₄ → Fe₃(PO₄)₂ + 6 NaCl
The molar mass of Fe₃(PO₄)₂ is 357.48 g/mol. The moles corresponding to 44.3 g are:
44.3 g × (1 mol / 357.48 g) = 0.124 mol
The molar ratio of Fe₃(PO₄)₂ to FeCl₂ is 1:3. The moles of FeCl₂ are:
3 × 0.124 mol = 0.372 mol
The molar mass of FeCl₂ is 126.75 g/mol. The mass of FeCl₂ is:
0.372 mol × (126.75 g/mol) = 47.2 g
Sea breeze, land breeze, mountain breeze, and valley breeze.

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:
9.2 L is the average volume should the chemical engineer report.
Explanation:
Volume of pollutant from Cross creek plants 10.88 L
Volume of pollutant from Oglala plants = 0.92 L
Volume of pollutant from Platte plants = 15.82 L
Average volume pollutants will be given by :
9.2 L is the average volume should the chemical engineer report.
Answer:
a. NO2
b. NH3
c. CO2
Explanation:
a. For the pair of compounds CO2 or NO2 the one with the highest boiling point is __________ .
The answer is NO2. It has a higher boiling point than CO2 because it exhibits dipole-dipole interactions.
b. For the pair of compounds NH3 or CH4 the one with the highest boiling point is _________
NH3 has a higher boiling point compared to CH4. This is due to the presence of the hydrogen bonds in NH3,
c. For the pair of compounds CS2 or CO2 the one with the highest boiling point is _________
CS2 has a higher boiling point than CO2. This is because of the high molecular mass of CS2.
