Why Solubility of salt is less in heavy water than normal?
It is an isotopic effect on solubility; the normal water is H2O or the heavy water is D2O.
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
The density of a liquid form of a material is always less than the density of the solid form of that same material?
Yes true, however this is not true of H2O or water. Water in solid form is actually less dense than its liquid form. That is why ice floats on water.
Who has the most polar bond H2O H2S H2?
H2 molecule is the least polar. Between H2O and H2S, the most polar will be H2O as oxygen is more electronegative than sulphur.
What molecule up more than half of the human body?
H2o
Is deionized water a mixture?
Pure, deionized water is a compound (H2O).
What is the formula for DI water alone?
Deionized water has the same formula as the water in a mud puddle: H2O. If the water is deionized, it has fewer ions dissolved in it but, since water is the universal solvent, even the glass container will dissolve to some extent in it. That it can dissolve other materials does not have any bearing on its chemical formula. Water is water and the formula is H2O.
Why hf is less viscous than h2o?
Due to strong H-bonding in H20 than HF.That is why HF IS LESS VISCOUS
Why h2O Is liquid and H2O is gas?
Change in the state of matter. It is the same thing but, one is under less pressure or higher temperature (or both) than the other.
What is the name of the conjugate base H3O plus?
The conjugate base differs ONE proton (less) than the acid.H3O+ --> H2O + H+so H2O is the conjugate base of H3O+
Why does a steel ball sink in water but a toy ship made of steel floats?
Density of a steel ball is greater than the den. Of h2o - it sinks similarly den. Of a toy ship is less than the den. Of h2o - it floats
What do molecules of ice have less of than molecules of water?
The chemical formula is absolutely identical - H2O. The density of ice is lower than the density of water.
What is unique about H2O when it freezes?
It expends on freezing and its solid state (Ice) is less denser than liquid state (Water).
Why bond angle of H2S is less than H2O?
The larger the central atom is the less the hydrogens have to spread out (because the electron repulsions are smaller) and the smaller the resulting angle.
What is water often called?
H2O hydrogen
What is the formula for purified water?
H2 0 is the formula for water h two o although every 1^-7th molecule is split in H+ and OH-...
Why Solubility of salt is less in heavy water than normal?
It is an isotopic effect on solubility; the normal water is H2O or the heavy water is D2O.
