A). Remove contaminated clothing, shoes, jewelry and your laboratory coat. Ask someone in the laboratory to assist you.
Immediately flush the area with copious amounts of water for at least 15 minutes. If your eyes do not require flushing, attempt to protect the eyes from cross contamination.
Seek medical attention after washing the affected area for 15 minutes and call 911 or go to the nearest emergency care facility.
B). Don't rub the eye — this may cause further damage.
Don't put anything except water or contact lens saline rinse in the eye. And don't use eyedrops unless emergency personnel tell you to do so. Flush your eye with water. Use clean, lukewarm tap water for at least 20 minutes.

Calculate the work, w, gained or lost by the system when a gas expands from 15 L to 45 L against a constant external pressure of
marta [7]

Answer:

Work done by the system = 4545 J

Explanation:

The expression for the calculation of work done is shown below as:

w=-P\times \Delta V

Where, P is the pressure

\Delta V is the change in volume

From the question,  

\Delta V = 45 - 15 L = 30 L

P = 1.5 atm

w=-1.5\times 30\ atmL

Also, 1 atmL = 101 J

So,  

w=-1.0\times0.75\times 101\ J=-4545\ J (negative sign implies work is done by the system)

<u>Work done by the system = 4545 J</u>
