Answer:
True
Explanation:
Hydrogen has three naturally occuring isotopes and copper has two.
Answer:
Heat flows from the reactor to the water
Explanation:
The thermal energy mentioned in the description is another way to say heat. The energy that is produced by the nuclear reactions leaves the reactor and enters the water, warming it.
The passage does <em>not </em>say that heat flows in the form of electricity, but rather that the turbines turned by the steam produce electricity.
The passage does <em>not </em>say that the steam produces the heat, but rather that the boiling of the water (caused by the heat) produces steam.
Answer:
Disilicon Hexabromide
Explanation:
A compound H2O is named – Dihydrogen monoxide. Its common name is of course water. A compound of Si2Br6 is named – Disilicon Hexabromide. 2.
Association Effects in Alcohols:
A broad peak is found in the IR spectrum of Alcohols in the range of 3500 cm⁻¹. The broadness is mainly due to special class of association effect called as hydrogen bonding. Hydrogen bonding mainly occur between the most electronegative element (F, O or N) of one molecule and the the hydrogen atom (attached to most electronegative atom) of another molecule.
Association Effects in Carboxylic Acids:
In carboxylic acids the -COOH group is responsible for the broadness of peak in IR spectrum at around 2600-3400 cm⁻¹. This broadness again results from the association effects called as dimerization in which a dimer of carboxylic acid is formed.
Association effect in Water:
The association effect found in water is also due hydrogen bond interactions as that found in case of Alcohols.
