I would assume so.
Given
, we can simplify the fraction to 
Both would obtain the same proportions, so I don't see why putting a half cup of sugar would make things any different.

Hello!
In this case, since we are asked to note down the complete molecular equation, complete ionic equation and the net ionic equation for the reaction between acetic acid (weak acid) and barium hydroxide (strong base), we proceed as shown below:
- Complete molecular equation:
- Complete ionic equation: in this case, since acetic acid is a weak one, it is not ionized, so we do this:
- Net ionic equation: in this case, we cancel out the barium ions as they are the spectators one because they are present at both reactants and products:

Answer:
7.6 days
Explanation:
Radon is a radioactive element and Radon-222 is it's most stable isotope. The half-life of Radon-222 has been found to be approximately 3.8 days.
Let, the initial amount of the Rn-222 = 1 = A
Final amount = = A'
We will use the following relation for calculating time elapsed in the decay
Thus,
We can write is as,
Since the base in both sides are equal, powers can also be equal and thus,
So, t = 7.6 days
