How can a scientist assess whether a pure niobium (Nb) sample is responsible for contaminating the lab with radioactivity? Test the niobium sample to see whether it now contains other elements.
Test the niobium sample for the presence of niobium oxide compounds.
Heat the niobium, and see if the level of radioactivity in the lab increases.
Place the niobium under pressure, and see if the level of radioactivity in the lab increases.
Answers
The 2nd choice doesn't work because niobium oxides aren't radioactive (unless the niobium itself was radioactive, but you can't tell with this method).
The last 2 choices don't work because temperature and pressure don't affect the rate of decay.
A scientist can assess whether a pure niobium (Nb) sample is responsible for contaminating the lab with radioactivity by A. Testing the niobium sample to see whether it now contains other elements.
What is radioactivity?
It should be noted that radioactivity simply means the natural process through which atoms disintegrate.
In this case, the scientist can assess whether a pure niobium (Nb) sample is responsible for contaminating the lab with radioactivity by testing the niobium sample to see whether it now contains other elements.

Explanation:
In chemistry, internodes refer to the points in the structure of a molecule or molecular chain where carbon atoms are located. Internodes are carbon atoms that are directly connected by a single bond. These carbon atoms are often called "C" followed by a number indicating their position in the chain. Carbon atoms that are not internodes are called "terminal carbons" and are bonded to other atoms or chemical groups. The structure of internodes and terminal carbons is important for understanding the geometry and reactivity of organic molecules.

Answer:
The complete photosynthesis equation is:
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2
This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O), in the presence of light energy, react to produce glucose (C6H12O6) and oxygen (O2).
Final answer:
The photosynthesis equation is: 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen.
Explanation:
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. The equation for photosynthesis is:
6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
In this equation, carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of light energy.
During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The process takes place in the chloroplasts of plant cells, specifically in the chlorophyll-containing organelles called chloroplasts. Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose and oxygen.
