What is the empirical formula for ribose (C5H10O5)?
C. CH20
Answer:High-purity chemicals are all-the-more important during the manufacturing process because chemicals are often used in bulk. ... In plastics, for example, an impure chemical substrate can produce an end-product that's too brittle to use. In pharmaceuticals, one impure component can render a drug dangerous
Explanation:
It would be.. sand, slit, clay.
the process for refining a metal in an electrolytic cell, in which the impure metal is used as the anode and the refined metal is deposited on the cathode.
Answer:
1. 2C8H18 + 25O2 —> 16CO2 + 18H2O
2. The coefficient of O2 is 25
Explanation:
C8H18 + O2 —> CO2 + H2O
The above equation can be balance as follow:
There are 8 atoms of C on the left side and 1 atom on the right side. It can be balance by putting 8 in front of CO2 as shown below:
C8H18 + O2 —> 8CO2 + H2O
There are 18 atoms of H on the left side and 2 atoms on the right. It can be balance by putting 9 in front of H2O as shown below:
C8H18 + O2 —> 8CO2 + 9H2O
Now, there are a total of of 25 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 25/2 in front of O2 as shown below:
C8H18 + 25/2O2 —> 8CO2 + 9H2O
Multiply through by 2 to clear the fraction as shown below :
2C8H18 + 25O2 —> 16CO2 + 18H2O
Now the equation is balanced.
2. 2C8H18 + 25O2 —> 16CO2 + 18H2O
From the balanced equation above, the coefficient of O2 is 25
