The pH unit has 10x as many hydrogens ions as the unit above.
Ex: A pH of 5 would have 10x more hydrogen ions than a pH of 6
and 100x more than if it had a pH of 7.
With a pH of 9 and 3, this is equivalent to 10⁶
So your answer should be:
1,000,000
Answer:
Actual yield = 20.52 g
Explanation:
Given data:
Theoretical yield = 25.3 g
Percentage yield = 81.1 %
Actual yield = ?
Solution:
Formula:
Percentage yield = Actual yield /theoretical yield × 100
81.1 % /100 = Actual yield / 25.3 g
0.811 = Actual yield / 25.3 g
Actual yield = 0.811 × 25.3 g
Actual yield = 20.52 g
Answer:
c
Explanation:
because u need the energy to be able to work
There are 7 digits from decimal to 1st digit, and it's coming from right, so exponent will be in negative 7
