HELP PLZ The formula for the pH of a solution of hydronium ions is given by the logarithmic equation pH=-log[H3O+] where [H3O+] is the hydronium ion concentration. Find the hydronium ion [H3O+] concentration for the substance with the given pH. Fruit juice, 3.2

Round to the nearest tenth, use scientific notation.

D-no effect on the rate

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is

Butterfly wingspan is 7.7

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
