The chemical warfareagent that attacks primarily the airway and the lungs would be a choking agent. It would cause irritation of the whole respiratory system resulting to dry-land drowning. Examples are chlorine gas, phosgene, acrolein and chloropicrin.

Answer:

154.44 Kg of H₂

Explanation:

We'll begin by converting 139 Kg of water to grams. This can be obtained as follow:

1 kg = 1000 g

Therefore,

139 kg = 139 kg × 1000 g / 1 Kg

139 Kg = 139000 g

Next, the balanced equation. This is illustrated below:

2H₂ + O₂ —> 2H₂O

Next, we shall determine the mass of H₂ that reacted and the mass of H₂O produced from the balanced equation. This can be obtained as follow:

Molar mass of H₂ = 2 × 1 = 2 g/mol

Mass of H₂ from the balanced equation = 2 × 2 = 4 g

Molar mass of H₂O = (2×1) + 16

= 2 + 16

= 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

4 g of H₂ reacted to produce 36 g of H₂O.

Next, we shall determine the mass of H₂ needed to produce 139 kg (i.e 139000 g) of H₂O. This can be obtained as follow:

From the balanced equation above,

4 g of H₂ reacted to produce 36 g of H₂O.

Therefore Xg of H₂ will react to produce 139000 g of H₂O i.e

Xg of H₂ = (4 × 139000)/36

Xg of H₂ = 154444 g

Finally, we shall convert 154444 g to kg this can be obtained as follow:

1000 g = 1 Kg

Therefore,

154444 g = 154444 g × 1 Kg / 1000 g

154444 g = 154.44 Kg

Thus, 154.44 Kg of H₂ is needed to produce 139 Kg of water H₂O

What is one advantage of doing a feild experiment instead of a laboratory experiment
Ber [7]

Answer:

  Field experiments can often have the potential to give scientists opportunities that are not possible in a lab setting.

Explanation:

  Having people "act natural" in a lab setting is impossible to truly achieve, as we all know what happens to our mental state and behavior when we are being actively observed. This is also especially helpful when conducting wildlife research, as there are a myriad of different things influencing animal and plant behavior that would be nigh impossible to recreate perfectly in a controlled lab setting.

  Field research can have its disadvantages as well, as it is very hard to only have one thing change (make an independent variable) in a wild environment with ever-changing weather, social effects, etc. Also, you, as the researcher, as causing an impact on the very location that you are observing, which can alter your results in unpredictable ways.

  The thing to remember is that each type of study has its advantages and disadvantages; if they didn't, then we'd all do the same type of research! You have to weigh your research options and figure out which one works best for your situation :)
