Answer:
Option (3).
Explanation:
Batch culture may be defined as a type of culture which are refereed as stack and operated as influx of the reactant up to the maximum level. This technique is generally used to grow the micro organisms.
The cell mass do not decrease or increases as the cell divides in the batch culture. The new batch are added during the culturing process. The cell mass remains constant in batch culture.
Thus, the correct answer is option (3).
Answer:
4 Fe + 3 O₂ → 2 Fe₂O₃
Explanation:
Let's start with the oxygen.
Reactants - 2
Products - 3
What number do 2 and 3 have in common? 6.
Put a 3 in the reactants and a 2 in the products to balance the oxygen.
Fe + 3 O₂ → 2 Fe₂O₃
Now let's look at the iron.
Reactants - 1
Products - 4
Put a 4 in the reactants to balance the iron.
4 Fe + 3 O₂ → 2 Fe₂O₃
The equation is balanced. Hope that helps.
