Answer & Explanation:
The given number above, 0.002353, may be rounded to only two significant figures by adding 1 to the 3 which is in the fourth place of the decimal position. This becomes, 0.0024. Addition of 1 was done because the number that follows 3 in the original number is 5.
Answer:
I believe the answer is A, an Element.
Explanation:
It's a substance that cannot be broken down into simpler substances. If I'm wrong, let me know!
a laboratory for research in chemistry. chem lab, chemistry lab. lab, laboratory, research lab, research laboratory, science lab, science laboratory - a workplace for the conduct of scientific research.
Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies. Chemical properties- These are properties that can only be observed by changing the identity of the substance

The krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.
What is isotopes?
isotopes are defined as atoms with a constant number of protons but a variable number of neutrons. Despite having different masses and hence having different physical qualities, they have nearly identical chemical properties.
What is stable nuclide?
Since stable nuclides are not radioactive, they do not spontaneously decay into radioactive elements as happens with radionuclides. They are commonly referred to as stable isotopes when such nuclides are discussed in connection to particular elements.
The electron capture process will turn rubidium-83 into krypton-83. When a proton in the nucleus catches an inner electron and creates a neutron, this process is known as electron capture.
Therefore, krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.
