Answer:
the 18th group or the zero group
Answer:
6
Explanation:
You divide the initial sample weight (155) by 2 until you get to 2.42.
Answer: the concentration of C6H5 NH3+ = 0.031M
Explanation:
From question pH= 5.47
pH+pOH= 14
pOH= 14-5.47= 8.53
Using the Henderson Hasselbalch equation
pOH =pKb + log (salt/base)
8.53 = 9.13 + log(salt/0.125)
8.53-9.13= log(salt/0.125)
-0.6= log(salt/0.125)
Antilog (-0.6)=salt/0.125
0.251= salt/0.125
Salt conc.= 0.125×0.251=0.031M
4320 inches
(Multiply the length value by 36)
CH3OH + O2 = CH2O + H2O
If you add number 2 before some of these elements, they will be balanced. So:
<u>2CH3OH + O2 = 2CH2O + 2H2O
</u>
On the left, there are 2 atoms of C, 4 atoms of O (2O + O2), and 8 atoms of H (2 * H3 + 2H = 8H), and on the left, the same number of atoms is present.
