When a 13.0g sample of NaOH(s) dissolves in 400.0 mL water in a coffee cup calorimeter, the temperature of the water changes from 22.6C to 30.7C. Assuming that the specific heat capiacity of the solution is the same as for water, calculate:.
(a) the heat transfer from system to surroundings
(b) change in H for the reaction
NaOH(s) > Na+(aq) + OH-(aq)

The answer is tea due to the main ingredient being a herb that grows from the ground and sugar that grows from a stalk, i hope this : )     p.s.  can i be brainliest?

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
