The correct answer is False.
The density is 4 g/cm³ or 4000 kg/m³.
Density = mass/volume = 12 g/3 cm³ = 4 g/cm³
The measurement of 4 g/cm³ is already in <em>SI units</em>.
In SI <em>bas</em>e units,
Density = (4 g/1 cm³) × (1 kg/1000 g) × (100 cm/1 m)³ = 4000 kg/m³
Answer:
b
Explanation:
If a cell has transporters that are not well regulated, weak acids or weak bases can accumulate inside the cells and cause stress.
Nuclear chemist is most concerned with the study of radioactive isotopes.
<h3>What is radioactive isotopes?</h3>
- A chemical element in an unstable state that emits radiation as it decomposes and becomes more stable.
- Radioisotopes can be created in a lab or in the natural world. They are utilized in imaging studies and therapy in medicine. likewise known as radionuclide.
- For instance, soil and rocks contain naturally occurring radioactive isotopes of the elements Radium, Thorium, and Uranium.
- Water also contains trace levels of uranium and thorium. Air contains radon, which is a byproduct of radium's radioactive disintegration.
- There are 254 stable isotopes, although there are more than 3,000 radioisotopes, only roughly 84 of which are found in nature.
