The denser and thicker a liquid is, the higher the buoyancy of an object is. In other words, if the density of a certain fluid is greater than the density of an object. The object will have negative buoyancy. If the density of the fluid is less than the density of an object, then it will float so positive buoyancy. Is this true

It decreases by 4 is your answer mark brainliest 

Answerionic bond imfs are stronger than covalent;

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
