Answer:
B
Explanation:
it's on the internet and I just know because I did this before too
Given that,
The concentration of
TRIS = 0.30 M
The concentration of
TRIS+ = 0.60 M
Kb = 1.2 x 10^-6
pKb = -log Kb = - log
(1.2 x 10^-6) = 5.920
Now, by using the
Hendersonn equation,
pH = pKa + log
TRIS+/TRIS = 5.920 + log (0.60/0.30) = 6.221
<span>pOH=14-pH=14-6.221 =
7.779</span>
Answer:
CO2 (s) -->Co2 (g) will be the answer
It basically works like this:
You dry out the food
put it in this ceramic oven thingy surrounded with water
burn the food
the water will heat up
measure the water temperature in f
= calories
Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints.
in this case, you're finding the amount of energy is contained within it when combusted
