Which is more polar h2s or h2o?
H2O is more polar as oxygen is more electronegative than sulfur and will therefore attract the electrons more than sulfur
Which is more polar NH3 or H2O?
h2o
Why is the reaction SO2 plus H2O H2SO2 not balanced?
there are more oxygen atoms on one side than on the other
Why does ice float on water but sinks in methylated spirits?
The density of rubbing alcohol is 75% that of water. Thus ice (frozen water which is roughly equal in density to liquid water), sinks in rubbing alcohol since it has more mass per cubic millimeter than the alcohol does. In order to float, the object would have to be less dense than the alcohol per cubic space.
In the extraction of tea with methylene chloride and water will methylene chloride be the upper or lower level?
Just compare the densities of both water and CH2Cl2. Water is less dense and will be in the top (aqueous) layer. CH2Cl2 is more dense and will be on the bottom (organic) layer. Density H2O = 1.00 g/cm3 Density CH2Cl2 = 1.33 g/cm3
How dense is sodium chloride?
More dense than water. Maybe 1.5 with 1 being H2O.
Why does H2O have a higher melting point than CCl4?
It has to do with intermolecular forces. H2O has an oxygen with two hydrogens coming off of it. This forms two hydrogen bonds, which are much stronger than the London Dispersion Forces in CCl4. (Since CCl4 is non-polar, there are no Dipole-Dipole forces).
Will ccl4 and h2o form a homogeneous mixture?
Yes, they will form a homogenous mixture.
Which freezes faster fresh H2O or salt H2O?
fresh water, because salt water is more dense
Is Br2 more soluble in H2O or CCl4?
ccl4 will dissolve better in water because likes dissolves likes, H2O is non-polar an CCL4 is also non polar where as ch2cl2 is polar(different to water) there for it wont dissolve in water but CCL4 will^^This is not true: water is polar. Therefore, since CCl4 is non-polar, and CH2Cl2 is polar, and like dissolves like, CH2Cl2 is more soluble.
Does H2O have a higher melting point than CCl4?
Yes. Water melts at 0 ºC. Tetrachloromethane (Carbon tetrachloride) has a melting point of -22 ºC
What is the shape of a H20 molecule and a carbon tetrachloride molecule?
A H2O molecule is bent and a CCl4 is tetrahedral.
What is the coefficient distribution F of I2 between H2O and CCL4?
i think it will be (I2) aqueous / (I2) CHCi3
Which is more polar h2s or h2o?
H2O is more polar as oxygen is more electronegative than sulfur and will therefore attract the electrons more than sulfur
Would ccl4 dissolve in h2o?
No it wont because it is non-polar and hence cannot break the hydrogen bonds in water and get dissolved
Why glucose is not soluble in CCl4 but dissolve in water?
CCl4 is insoluble in water because it is non polar whereas water is polar. Polar substances are soluble in polar substances and nonpolar in nonpolar Polarity is determined by the electro-negativity of the atoms in the molecule as well as the arrangement of the atoms. in CCl4 the electrons are pulled towards the Cl and the arrangement ensures that the outside of the molecule is evenly negative while the inside is positive in H2O, the electrons are pulled towards the Oxygen but the arrangement of the molecules means that one side of the molecule is partially negative while the other side is partially positive P.S. look up the structures of both molecules and this will become more clear
How many molecules are in 7.2g H2O?
Formula mass / Formula weight / Molecular mass / Molecular weight of H2O = (1*2) + 16 = 18g 1 mol of H2O = 18g H2O 1 mol of H2O = 6.023 * 10^23 molecules In 18g H2O there are 6.023 * 10^23 molecules. So, In 1g H2O there are (6.023 * 10^23) / 18 molecules = 3.346 * 10^22 molecules Therefore, In 7.3g H2O there are (3.346 * 10^22) * 7.3 molecules = 2.443 * 10^23 molecules Ans: 2.443 * 10^23 molecules
