So yield = actual/predicted*100
You need to find the theoretical yield. CONVERT INTO MOLES. this is the 1st step you do in most calculation questions.

There are some fibres that are prepared by man by using chemicals, these are called synthetic fibres these are made of small units that join together to form long chains
PH= pKa + log( conjugate base/ conjugate acid)
Answer:
-1
Explanation:
According to this question, the oxidation state/number of H and O in C2H4O is +1 and -2 respectively.
The oxidation state of carbon in the compound can be calculated thus:
Where;
x represents the oxidation number of C
C2H4O = 0 (net charge)
x(2) + 1(4) - 2 = 0
2x + 4 - 2 = 0
2x + 2 = 0
2x = -2
Divide both sides by 2
x = -1
The oxidation number of C in C2H4O is -1.
