water and acids and bases

Question 1

benefits of ice having low denisty

Answer 1

water freezing at lakes, the low denisty of ice means the ice will remain on the surface, and the sruface layer of the ice insulates the water below from cold air temperatures, reducing the psssbility that the entire lake would freeze allowing aquatice life to survive

Question 2

what happened to cooled liquid water

Answer 2

the water molecules move slowl, a it freezes teh moelcules arrange in a way where each water molecule forms 4 hydrgoen bonds to 4 neighboruing water moleucles

Question 3

why does water form meniscus (when water at the top is curved)

Answer 3

molecules clinging on the glas cling to it and other water molecule cling to the molecules touching the glass forming the meniscus, they will travel up until gravity stops them.

Question 4

what are acids

Answer 4

acids produce hydrogen ions when dissolved inawter

Question 5

strong and weak aicds

Answer 5

strong acids are aicds that ionsise in water, hydrochloric ionises in water which fomrs hydrogen and clhorde ions
