- Q2Salt and other compounds dissolve easily in water, this makes water a useful:cohesiveacidsolventbond agent30s
- Q3When water freezes, it becomes less dense, which causes what direct result:it dissolvesit floatsit becomes acidicit bonds to other elements30s
- Q4When a solution has an excess of hydrogen ions (H+), the solution is:basicacidicpolarsaturated30s
- Q5Water has a high heat capacity, this is important for life on earth because:it dissolves quicklyit boils quicklyit changes temperature slowlyit forms bonds30s
- Q6The cohesion of water creates:polarityacidic compoundsdissociationsurface tension30s
- Q7Water's polarity causes what additional property?dissociationhigh heat capacitynonpolar molecules do not dissolve in itcohesion30s
- Q8Why is the fact that ice floats important for life on earth?it keeps the earth rotatingit does not build up on surfacesit causes tectonic plate slideorganisms can survive under the ice30s
- Q9A solution with a pH of 9 would be considered:basicacidicneutral30s
- Q10Transpiration occurs in plants when water evaporates from their leaves and effectively pulls water up from the roots. This would not be possible if it weren't for which property of water?high heat capacitydensitypolaritycohesion30s
