Answer: The statement is true
Explanation:
The half-life of a radioactive isotope is the time taken for half of the total number of atoms in a given sample of the isotope to decay.
For instance
The half-life of radium is 1622 years. This means that if we have 1000 radium atoms at the beginning, then at the end of 1622 years, 500 atoms would have disintegrated, leaving 500 undecayed radium atoms
Thus, the statement is true
The answer is.............................................. plasma
Answer:
Molarity= 0.071M
Explanation:
Molar mass of NaNO3= 23+14+(16*3)=85
n= m/M = 30/85= 0.353mol
V= 5L
Applying
n= CV
0.353= C×5
Simplify
C= 0.071M
The answer is 546K. If you need the answer in degrees Celsius you subtract 273 from 546 and get 273 degrees Celsius. I included how I got the answer in the photo below. Hope this helps!

- <em>The overall reaction for the citric acid cycle is as follows: acetyl-CoA + 3 NAD+ + FAD + GDP + P + 2H2O = CoA-SH + 3NADH + FADH2 + 3H+ + GTP + 2CO2. </em>
- <em>Many molecules in the citric acid cycle serve as key precursors for other molecules needed by cells.</em>
