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.
Explanation:
The light reactions of photosynthesis use water and produce Oxygen, NADPH.
The equation for photosynthesis :
→
The process of photosynthesis in two stages -
For a light reaction -
Net Input is of, ,
Net Output is of,
Number of moles is defined as the ratio of given mass in g to the molar mass.
The mathematical formula is:
Number of moles = (1)
Number of zinc atoms is equal to , by Avogadro number, number of moles can be calculated.
As, 1 mol= atoms, hence,
= 0.2822 mol
Now, from formula (1), calculate mass in g (molar mass of zinc = 65.4 g/mol)
0.2822 mol =
mass in g =
= 18.45588 g
Thus, by rounding off the above number, it will come near about 19 g approximately.
Hence, option (C) is the correct answer.
