Why is water so effective at hydrogen bonding? a there are two hydrogens, doubling the positive charge on the water molecule. b hydrogen is more electronegative than oxygen, so it is more likely to donate its electrons to oxygen. c the hydrogens in water are ionically bonded to the oxygen. d oxygen is very electronegative and strongly attracts hydrogen's electron.

Here is your answer:                                                                                                                                                                                                                                                   formula for volume: base*width*height=                                                                                                 5*2*10=100                                                                                   your answer is 100cm.
