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.

How much heat in joules is gained when a 34.5 g bar of gold is heated from 26.4°C to 75.3°C ?specific heat of gold on 0.129 J/gr
Sati [7]

Answer:

Q = 217.63J

Explanation:

Data;

Mass = 34.5g

T1 = 26.4°C

T2 = 75.3°C

c = 0.129J/g°C

Energy (Q) = mc(T2 - T1)

Q = 34.5 * 0.129 *(75.3 - 26.4)

Q = 4.4505 * 48.9

Q = 217.629J

Q = 217.63J

The heat gained was 217.63J

Vinvika [58]
<span>1,3-cylohexadiene i synthesized starting from cyclohexane in following 4 steps.

1) Free Radical Substitution Rxn:
 Halogenation of cyclohexane in the presence of UV yield chlorocyclohexane.

2) Elimination Rxn: Dehydrohalogenation of chlorocyclohexane yields cyclohexene.

3) Halogenation of Cyclohexene (Electrophillic Addition Rxn) gives 1,2-dihalocyclohexane.

4) Elemination Rxn: When dibromocyclohexane is treated with KOH and heated it gives 1,3-cyclohexadiene as shown below,</span>
