Making rough estimate of physical quantities is useful because it allow us to have an idea of how big or small a quantity is, it gives us the near result of the real quantity a matter contains. The approximate quantity obtained will give us information about the size of the quantity.
Arrow symbol →
Explanation:
The arrow symbol in a chemical equation separates the reactants from products.
A chemical reaction is process in which chemical changes leads to the formation of products from reactants.
The arrow symbol → is used to separate the reactants from products
⇆ shows reversibility of the reaction
↑ indicates that gas is given off as product

Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.
Answer:
5’ – TAC-GCA-CTG-3’
Explanation:
As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.
Purines include adenine (A) and cytosine (C)
Pyrimidine include thymine (T) and guanine (G)
Thus an A always pair with T and C always pair with G
Thus, the resulting poly peptide for the given amino acid sequence is
3'-ATG-CGT-GAC-5'
5’ – TAC-GCA-CTG-3’
