At room temperature, number of moles of distilled water is 1 x10^-7. Hope it cleared your doubt.
Answer: I say its Segmented body and radial symmetry im not sure if it is right
Explanation:
Lewis structure, which shows bonding electron pairs as Lines and any nonbonding electrons as dots.
A chemical bond is holds atoms collectively in molecules. Bonds get up from the electrostatic forces between definitely charged atomic nuclei and negatively charged electrons.
Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis image consists of an elemental image surrounded by way of one dot for each of its valence electrons: parent 1 suggests the Lewis symbols for the factors of the 0.33 length of the periodic table.
Lone pairs are discovered in the outermost electron shell of atoms. They may be diagnosed with the aid of using a Lewis shape. Electron pairs are therefore taken into consideration lone pairs if two electrons are paired however aren't utilized in chemical bonding.
It is representation of the valence shell electrons in a molecule. it's far used to expose how the electrons are arranged round individual atoms in a molecule. Electrons are shown as dots or for bonding electrons as a line between the two atoms.

Answer:
q=mAHf
Explanation:
When water change form from solid(ice) to liquid, it will need heat that depends on the heat of fusion(Hfus). If the form changed from liquid to gas it will use the heat of vaporization(Hvap) instead. The heat of fusion usually written just AT
q=MCAT is used to calculate heat when temperature change(AT = delta T= difference in temperature)
q=mAHvap is wrong because you need if the form change from liquid to gas
q=mc^2 is wrong because it describes the relation of mass and energy, not the form.
The answer should be q=mAHf
