What causes water molecules to be attracted to each other?

Chemistry

This polarity makes water molecules attracted to each other. The oxygen-hydrogen bond in the alcohol molecule is also polar. But, the carbon hydrogen bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared more or less evenly.

Answer:

Both polar covalent bonds inside each water molecule and hydrogen bonds inside each water molecule are liable for attraction between water molecules.

Explanation:

  • Water is a polar protic molecule.
  • Due to large difference in electronegativity between oxygen and hydrogen atom, two O-H bonds in water molecule are polar.
  • Due to the presence of polar covalent bonds in water molecule, water molecules attract each other through oppositely polarized ends.
  • In water molecules, H atom is attached with highly electronegative oxygen atom. Hence hydrogen bonding interaction arises between water molecules.
  • So, both option (A) and (B) are correct

By using the following reactions, calculate the heat of combustion of pentane:
Sergio [31]
To answer this problem, we use Hess' Law to calculate the overall enthalpy of the reactions. The goal is to add all the reactions such that the final reaction is C<span>5H12 (g) + 8O2 (g) → 5CO2 (g) + 6H2O (l) through cancellation adn multiplication. The first equation is multiplied by 5, the second one is multiplied by 6 and the third one is reversed. The final answer is -3538 J or -3.54 x10^3 kJ.</span>

How many grams of PbBr2 will precipitate when excess CuBr2 solution is added to 77.0 mL of 0.595 M Pb(NO3)2 solution?Pb(NO3)2(aq
Alexxx [7]

Answer:

16.89g of PbBr2

Explanation:

First, let us calculate the number of mole of Pb(NO3)2. This is illustrated below:

Molarity of Pb(NO3)2 = 0.595M

Volume = 77mL = 77/1000 = 0.077L

Mole =?

Molarity = mole/Volume

Mole = Molarity x Volume

Mole of Pb(NO3)2 = 0.595x0.077

Mole of Pb(NO3)2 = 0.046mol

Convert 0.046mol of Pb(NO3)2 to grams as shown below:

Molar Mass of Pb(NO3)2 =

207 + 2[ 14 + (16x3)]

= 207 + 2[14 + 48]

= 207 + 2[62] = 207 +124 = 331g/mol

Mass of Pb(NO3)2 = number of mole x molar Mass = 0.046 x 331 = 15.23g

Molar Mass of PbBr2 = 207 + (2x80) = 207 + 160 = 367g/mol

Equation for the reaction is given below:

Pb(NO3)2 + CuBr2 —> PbBr2 + Cu(NO3)2

From the equation above,

331g of Pb(NO3)2 precipitated 367g of PbBr2

Therefore, 15.23g of Pb(NO3)2 will precipitate = (15.23x367)/331 = 16.89g of PbBr2
