Answer:
modular
Explanation:
<em>The addition of extra liquid protein supplement to the tube feeding formula of Alice is an example of modular formula.</em>
<u>A modular formula consists of a deficient food supplements that is specifically rich in a particular macronutrient such as protein, carbohydrate, etc. </u>
The supplements in modular formula are usually in liquid from and are introduced into the tube feeding formula of a patient undergoing tube feeding.
In this case, the macronutrient in the liquid food supplement being given to Alice is protein.
Answer:
<h2>100°C is the boiling point of water in degrees Celsius</h2>
Answer:
d. Radon-222
Explanation:
²²⁶₈₈Ra → ²²²₈₆Rn + ⁴₂He
Alpha particle is a helium nucleus with mass number 4 and atomic number 2. According to the law of conversation of mass, the sum of the mass number and atomic number must be equal on both side of the reaction.
Since the mass number of Ra is 226 and that of He is 4. The mass number of the unknown element must be 226 - 4 = 222.
Since the atomic number of Ra is 88 and that of He is 2. The atomic number of the unknown element must be 88 - 2 = 86.
Now looking in the periodic table Radon is the only element with atomic number 86.
What part of it are you confused about
Answer:
k= 1.925×10^-4 s^-1
1.2 ×10^20 atoms/s
Explanation:
From the information provided;
t1/2=Half life= 1.00 hour or 3600 seconds
Then;
t1/2= 0.693/k
Where k= rate constant
k= 0.693/t1/2 = 0.693/3600
k= 1.925×10^-4 s^-1
Since 1 mole of the nuclide contains 6.02×10^23 atoms
Rate of decay= rate constant × number of atoms
Rate of decay = 1.925×10^-4 s^-1 ×6.02×10^23 atoms
Rate of decay= 1.2 ×10^20 atoms/s
