Answer:

Cocaine

Explanation:

The Scott test is a presumptive, qualitative colorimetric test for the presence of cocaine that is carried out in the laboratory or on the field. It consists of 3 steps;

  • Suspected substance is mixed with cobalt thiocyanate in an aqueous/glycerin solution.
  • Acidification of the resulting solution using HCl.
  • Extraction of substance's precipitate using chloroform

<em>Blue organic phase indicates the presence of cocaine in substance while colourless organic phase indicates the absence.</em>

nekit [7.7K]
Molar mass of oxygen is:
M(O)=16 g/mol
Molar mass of carbon is:
M(C)=12 g/mol  
Molar mass of carbon dioxide is:
M(CO2)=M(C)+2*M(O)
 M(CO2)=12 g/mol+2*16g/mol
M(CO2)=44 g/mol

What mass of H2O is produced by the combustion of 1.00 mol of CH4?
kkurt [141]
CH4 : H2O
1 : 2

number of moles of H2O = 1.00 x 2
number of moles of H2O = 2.00mol

mass = number of moles x molar mass

mass of H2O = 2.00 x (1 + 1 + 16)
mass of H2O = 36g

1. What is the potential energy of a 8 kg ball that is at a height of 20 m?
weqwewe [10]

Answer:

1. 1568 J

2. 0 J

3. 1176 J

Explanation:

PE = mgh

(PE = Potential Energy) = (m = mass)(g = gravitational force which is 9.8)(h = height)

1. (3)(9.8)(20) = 1568 J

2. PE = (3)(9.8)(0) = 0 J

3. (5)(9.8)(24) =  1176 J
