Answer:
universal mass unit
<h2 />
The universal mass unit, abbreviated u (sometimes amu for atomic mass unit), is defined as one-twelfth of the mass of the 12C atom which has been defined to be exactly 12 u. The absolute mass of a 12C atom is obtained by dividing the value 12 by the Avogadro number (NA = 6.022 137 × 1023).
Answer:
Baking Soda, Vinegar, Ammonia
Explanation:
Half life is determined using the equation expressed as:
A = Ao e^-kt
First, we need to find for the value k.
A = .67Ao = Ao e<span>^-k(33 min)
k = 0.0121
The half-life is then calculated as follows:
</span>A = .5Ao = Ao e<span>^-0.0121(t)
</span><span>t = 57.28 min
</span>
