Answer:

Hydrogen Chloride Gas is heavier than air and sinks to the ground after being released. Firefighters closer to the ground will be subjected to significantly greater concentrations of hydrogen chloride gas than the firefighters walking on top of railcars.

Explanation:

The molar mass of air is 28.97 g/mol. Air is approximately 78% N2, which has a molar mass of 28.014 g/mol and 21% oxygen, which has a molar mass of 32 g/mol; the remaining constituents of air include CO2 and other trace amounts of gases.

The molar mass of HCl is 36.458 g/mol.

Because HCl is heavier than air, it sinks toward the ground, displacing the lighter air.

The height of railway cars is reported to vary between 13.5 ft to 15.5 ft. So firefighters on tank cars are generally above the HCl gas (although localized atmospheric conditions could cause the HCl to move higher up in the air column).

Some of them yes but some of them no.

Explanation:

When the tsunami moves across other bodies of water it initially gets bigger. When it is moving across the water it is picking up molecules as well as dropping them off. But the farther away the tsunami gets from the water the smaller it gets.

What concentration of clo3– results when 925 ml of 0.393 m agclo3 is mixed with 685 ml of 0.283 m mn(clo3)2?
docker41 [41]

Answer;

= 0.7698 M

Explanation and solution;

AgClO3 ionizes as follows:  

AgClO3 ---> Ag^+ + ClO3^-  

Moles AgClO3 dissolved ---> (0.393 mol/L) (0.925 L) = 0.424865 mol

From the chemical equation, one mole of AgClO3 dissolving yields one mole of ClO3^- in solution.

Moles ClO3^- = 0.424 865 mol

Similarly;

Mn(ClO3)2 dissolves as follows:

Mn(ClO3)2 ---> Mn^2+ + 2ClO3^-

Moles Mn(ClO3)2 dissolved ---> (0.283 mol/L) (0.685 L) = 0.413139 mol

From the chemical equation, one mole of Mn(ClO3)2 dissolving yields two moles of ClO3^- in solution.

Moles ClO3^- = 0.413139 mol x 2 = 0.826277 mol  

Total moles ClO3^- in solution;

0.826277 mol + 0.413139 mol = 1.239416 mol  

Total volume of solution ---> 0.925 L + 0.685 L = 1.61 L  

Molarity of ClO3^- ---> 1.239416 mol / 1.61 L = 0.7698 M
