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?
Not always - the density of a liquid may be greater or less than that of the solid form depending on the molecular structure and arrangement. For example, water is an exception as its solid form (ice) is less dense than its liquid form.
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
What molecule makes up more than of the human body?
H2o
Is deionized water a mixture?
No, deionized water is not a mixture. It is a type of water that has had its ions (charged particles) removed through a process called deionization, resulting in a more pure form of water with a neutral pH.
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 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 bond angle in H2S (92 degrees) is less than in H2O (104.5 degrees) due to the larger size of sulfur compared to oxygen. The larger size of sulfur results in weaker repulsions between the electron pairs, causing the bond angle to be smaller in H2S compared to H2O.
What is water often called?
Water is often referred to as H2O, dihydrogen monoxide, or the universal solvent.
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+
What is Difference between ionized and deionized Water?
Ionized water has been altered to have more ions present, usually through the use of an ionizer machine, which can affect its pH and potential health benefits. Deionized water, on the other hand, has had all ions removed through a process of ion exchange or distillation, making it essentially pure H2O with a neutral pH.
Why is CaSO4 less soluble in water than NaCl?
The ion-ion bond in CaSO4 is stronger than in NaCl because of the higher charges on the cation and anion. Be careful in making this argument. The ion-dipole forces of Ca2+ -H2O and SO42- - H2O might actually be stronger than that of Na+ -H2O and Cl- -H2O due to the high charges on Ca2+ and SO42- . However the strengths of the ions-dipole interactions do not match (or exceed) the strength of the Ca2+ -SO42- ionic bond.
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
Which is the weaker acid HSO4 or H2O?
H2O is a weaker acid compared to HSO4. Water (H2O) has a weaker tendency to donate a proton (H+) compared to bisulfate ion (HSO4-). This is because the dissociation of water into H+ and OH- ions is less favorable than the dissociation of bisulfate ion into H+ and SO4^2-.
