energy. The process, known as the Hall-Héroult process, involves electrolysing aluminum oxide (Al2O3) to extract pure aluminum. This requires a significant amount of electricity to separate the aluminum from the oxygen in the ore.

How phosphorus in aluminum electrolysis affects current efficiency?

Phosphorus increases electrical resistance so it would negatively effect current efficiency in the electro chemical process of smelting aluminum. That is why Phosphorus is not used in primary production of aluminium. The process of taking refined bauxite (alumina) and turning it into pure aluminum uses an enormous amount of electrical power so any reduction of electrical resistance can improve efficiency and save a great deal of money.

Why is the melting point of silicon much higher than that of argon even though argon has a greater molar mass?

Because Argon exists as diatomic Ag2 molecules, with relatively weak inter-mocular forces (Van-der-Waals forces) between the molecules. Melting Argon only requires that these inter-olecular forces are overcome, which does not requires much energy as the molecules are small - so Argon melts at -189 degrees celcius - so is a gas at R.T.P Silicon on the other hand exists in a macro-molecular form, and all the atoms are covalently bonded to each other in a giant molecular lattice. To melt silicon, covalent bonds must be broken, which requires a great deal of energy, and hence silicon only melts at 1414 degrees celcius

What does DNA replication requires a great deal of?

DNA replication requires a great deal of energy, as it involves the synthesis of new DNA strands through the addition of nucleotides. This process is facilitated by various enzymes, such as DNA polymerase, which also necessitate ATP (adenosine triphosphate) to drive the reactions. Additionally, accurate replication depends on the coordination of numerous proteins and factors to ensure that the DNA is copied faithfully and efficiently.
