How do we draw the dipole moment of a water molecule?
2017年4月5日 · Looking at the electronegativity and shape of the "H"_2"O" molecule tells you how the arrow depicts the polarity: from in between the hydrogen atoms to the oxygen atom. (See explanation) We start by looking at a water molecule: As we can see, the 2 hydrogen atoms are covalently bonded to the oxygen atom, which has two lone pairs (4 total electrons that push …
How many dipoles are there in a water molecule? - Socratic
2014年11月8日 · There are three dipoles in a water molecule. Since O is more electronegative than H, the O-H bond is polar. The negative end is at the O atom, and the positive end is at the H atom. There are two O-H bonds, so there are two bond dipoles. These two bond dipoles are vectors. They combine to form a vector sum with the resultant pointing from the mid-point …
What is the approximate mass of one water molecule?
2015年10月29日 · You can determine that by using the molar mass in "g/mol" of the water molecule and converting so that you get the absolute mass in "g". The molar mass is "MM"_("H"_2"O")" = 18.015 g/mol". If you don't remember that, you can also look it up on Wikipedia, or refer to a periodic table and add up the molar masses of two hydrogen atoms …
What is the shape of a water molecule? - Socratic
2016年4月29日 · Bent. The central oxygen atom has 2 non-bonding pairs of electrons, and 2 pairs of shared bonding electrons, each to a hydrogen atom. The arrangement of the electron pairs around the central oxygen is tetrahedral, with the non-bonding pairs taking up slightly more space than the bonding pairs, but since we don't "see" the the electrons but only the atoms, the …
What is the total number of electrons in a water molecule?
2024年5月24日 · In a water molecule (not an ion - just the molecule) the protons and electrons are matched in number. The hydrogen has 1 proton each. Oxygen has 8 protons. Since water is H2O, you have 2x1 + 8 ...
What is the bond angle in a water molecule? - Socratic
2015年11月15日 · 104.4776^@ You can derive the approximate angle by knowing that the oxygen in water has four electron groups, giving it a tetrahedral electron geometry, and a bent molecular geometry. From knowing that it has a tetrahedral electron geometry, but two lone pairs of electrons, one question should pop into your mind: "Why does water not have a 109.5^@ H …
Why is water a polar molecule? - Socratic
2018年5月16日 · Water #(H_2O)# is a polar molecule because the electrons of the hydrogen atoms get "pulled" towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom. Have a look here: This also allows for hydrogen bonding.
What is the mass of ONE water molecule? - Socratic
2017年4月30日 · You know that one mole of water, i.e. #N_A# water molecules, has a mass of #18.01*g#.And thus to get the mass of ONE water molelcule, we divide this molar mass by #N_A=6.022xx10^23#
What type of chemical bond holds atoms together within a water …
2016年4月4日 · Covalent Bond Hydrogen and oxygen are non-metals. They bonded together through covalent bonding. Instead of losing electrons, hydrogen and oxygen share their electrons so that they have full outer shells.
How many atoms are in one water molecule? + Example - Socratic
2016年11月3日 · The molecular formula for water is H_2O, meaning there are 2 hydrogen atoms and one oxygen atom. I found this by adding the subscripts. 2 is the subscript on hydrogen, and 1 is the subscript on oxygen, so 2 + 1 = 3 atoms total. For example, to count the number of atoms in one molecule of glucose, C_6H_12O_6, add the subscripts, so 6+12+6 is 24 ...
