Provide an explanation on how adding soap to water helps to emulsify oils and fatty substances?

All chemicals used in the chemistry lab can be discarded down the sink and must be done so when the experiment is over.

Your laboratory has a fire blanket, eyewash fountain, safety shower and a first aid kit.

It is good laboratory protocol to inform other students if they are not following good laboratory practices. If they continue, then you should “rat” on them to the instructor.

IDENTIFY THE FOLLOWING PLANE

Open toed-shoes, like sandals and flip-flops, are prohibited in the lab.

Indicate whether the reaction is a single displacement, double displacement, decomposition, or synthesis reaction. 1)  H2O(l)   +   CO2(g)  ———>   H2CO3(aq)     [A] 2)  Pb(NO3)2(aq)  +  2 Al2(SO4)3(aq)   ————->  PbSO4(s)  +   3 Al(NO3)2(aq)    [B] 3) 2 AgNO3(aq)    +   CoCl2(aq) ———-> 2 AgCl(s)   +   Co(NO3)2(aq)     [C] 4) H2CO3(aq)  ———————>    H2O(l)  +  CO2(g)      [D] 5)  CuSO4

It is OK to leave a Bunsen Burner on and burning when not in use.

Zeros recorded in a measurement are never used as significant figures.

Indicate whether the reaction is a single displacement, double displacement, decomposition, or synthesis reaction. 1) Na2CO3(aq)   +  2 HCl(aq)  ———>  2 NaCl(aq)   +  H2CO3(aq)     [A] 2) 3 CuSO4(aq)  +  2 Al(s)   ————->  Al2(SO4)3(aq)  +   3 Cu (s)    [B] 3) 2 AgNO3(aq)    +   CuCl2(aq) ———-> 2 AgCl(s)   +   Cu(NO3)2(aq)     [C] 4) H2CO3(aq)  ———————>    H2O(l)  +  CO2(g)      [D] 5)  CuSO4
