Why does wood float besides it being less dense

The only reason wood floats is because it is less dense and has big openings and gaps which allows air in.

Wood that sinks has very tiny openings. The ratio between weight and volume is called density. An object that is less dense than water can be held up by water, and so it floats.

Hope this helps! please mark me brainliest!

God bless :)

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

you gotta add the following molecules so we can give u an answer
