Answer:
C. increase to 7.
Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Thus, the molar relationship is 1 to 1, therefore, the moles are:

Thus, since the entire hydrogen ions are neutralized, the pH C. increase to 7.
Best regards.
Answer:
No they are not the same the are both di
That is called condensation
It mean it consisted of 1 g of lead and 0.077 g of O2.
divide these numbers by molar mas.
1/82=0.012 Pb /0.004 = 3
0.077/16= 0.004 O /0.004 =1
Pb3O
