Which are effects of long-term exposure to mustard gas? Select all that apply. One, some, or all responses may be correct.

Answers

The effects of long-term exposure to mustard gas causes mortality and chronic respiratory disease.

Exposure to mustard gas in the long term can result in mortality from influenza, pneumonia as well as chronic breathing disease. Exposure for long term leads to respiratory complications and septic shock. Extensive breathing in the environment of mustard gas can cause chronic respiratory disease, respiratory infections or death.

Extensive eye exposure to this gas can cause permanent blindness. Exposure to mustard gas may also increase the chances of lung and respiratory cancer so we can conclude that mustard gas is lethal and can cause a number of diseases in a person who is exposed to it.

How to differentiate between ionic and covalent bonds ?

There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.


Properties of nonmetals include

a.high boiling point.
b.ability to conduct heat.
c.dull appearance.
d.none of the above

Answer:

c.dull appearance

Explanation:

Nonmetals are dull,poor conductors of heat and electricity that have lower melting points than metals,the rest of the answer choice are properties of metal.

9) What is the final pressure in the container shown below after the valve is opened and the gases are allowed
to flow? (The gases do not act)
0
4.00 am
3.00


NE
2.00 am
2.00 L

Answers

A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.

We have 2 containers connected by a valve.

One container has a volume of 3.00 L and contains O₂ at 4.00 atm. The other container has a volume of 2.00 L and contains Ne at 2.00 atm.

When the valve is opened, the total volume is the sum of the 2 containers.

[tex]V_2 = 3.00 L + 2.00 L = 5.00 L[/tex]

Assuming constant temperature and ideal behavior, we can calculate the final pressure of each gas using Boyle's law.

O₂

[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{4.00atm \times 3.00L}{5.00L} = 2.40atm[/tex]

Ne

[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{2.00atm \times 2.00L}{5.00L} = 0.800atm[/tex]

The final pressure in the container will be the sum of the final pressures of the gases.

[tex]P = 2.40 atm + 0.800 atm = 3.20 atm[/tex]

A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.
