Answer:
sulfur
Explanation:
In oxygen family sulfur has yellow color and also having stinky smell. Thus given statements are about sulfur.
It is present in oxygen family.
It has six valance electrons.
Its atomic number is 16.
Its atomic weight is 32 amu.
The electronic configuration of sulfur is given below,
S₁₆ = 1s² 2s² 2p⁶ 3s² 3p⁴
We can see the valance shell is third shell and it have six electrons thus sulfur have six valance electrons. (3s² 3p⁴ )
Sulfur is used in vulcanisation process.
It is used in bleach and also as a preservative for many food.
it is used to making gun powder.
 
        
             
        
        
        
Answer:
C2H5NO
Explanation:
constituent elements                    N              O               C                H
Mass composition                     0.420        0.480         0.540         0.135
mole ratio                                   0.42/14       0.48/16      0.54/12         0.135/1
                                               = 0.03                0.03             0.045         0.135
dividing by the smallest           0.03/0.03     0.03/0.03    0.045/0.03 0.135/0.03
ratio                                      =        1                      1                1.5                 4.5
                                              =        1                      1                  2                   5
EMPERICAL FORMULA = C2H5NO

Answer:
<h2>62,560 kg</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
volume = 34,000 L
density = 1.84 kg/L
We have
mass = 1.84 × 34,000 = 62,560 
We have the final answer as
<h3>62,560 kg</h3>
Hope this helps you
