the last one
Explanation:
one atom had a higher electronegativity than the atom it is sharing with.
They contain both carbon and hydrogen :)
Answer:
0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.
Explanation:
According to reaction, 1 mole of sulfuric acid reacts with 2 moles of sodium hydroxide.
Then 1.8 moles of sulfuric acid will react with:
moles of NaOH.
Molarity of NaOH = 4.0 M
Moles of NaOH= n = 3.6 mol
Volume of NaOH = V
0.9 liters of 4.0 M NaOH solution will react with 1.8 moles of sulfuric acid.
Answer:
a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.
