A beta particle is simply a high energy electron that is emitted from the nucleus. It DOES NOT affect the mass number of radioactive element TC, but affects the ATOMIC NUMBER by increasing it by 1 in Ru.
Thus mass number 99 remain the same in TC and Ru, but Atomic number increases from 43 to 44 due to beta decay
I believe the one with 2 cups of water will be saltier
Explanation:
When you change the fractions to a common denominator, which is 12, you see the recipe with 1 cup should be half of the recipe with 2 cups. But the one with 2 cups is more than double the recipe with 1 cup.
