EDTA stands for ethylenediamine tetra - acetic acid. It is a crystalline acid with a strong tendency to form chelates with metal ions.
Answer:
The answer to your question is Isotope
Explanation:
Isotopes are atoms with the same number of protons and electrons but their atomic mass is different due to their number of neutrons is different.
In this kind of elements, the number of protons stays the same.
Some isotopes are radioactive but others do not.
Some isotopes are used to know the age of fossils or ancient things.
Answer:
D they are quickly replenished. I get this question a good bit so i know the answer.
Explanation:
Answer:
Hope this helps
Explanation:
These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.
The first is the electron's energy level or "shell", used as n. (Principle QN)
The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)
The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)
The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)
Answer:
Mass = 90.1 g
Explanation:
Given data:
Number of moles of carbon dioxide = 3 moles
Mass of glucose produced = ?
Solution:
Chemical equation:
6H₂O + 6CO₂ → C₆H₁₂O₆ + 6O₂
Now we will compare the moles of CO₂ and C₆H₁₂O₆.
CO₂ : C₆H₁₂O₆
6 : 1
3 : 0.5
Mass of glucose:
Mass = number of moles × molar mass
Mass = 0.5 mol × 180.2 g/mol
Mass = 90.1 g
